MiCO MiCOM M P13 P139 Time Overcurrent Protection and Control Unit Application and scope The MiCOM P139 is a cost effective one box solution for integrated numerical distance protection and control. The protection functions provide selective short-circuit protection, ground fault protection (UK: earth fault) and overload protection in medium, high and extra high voltage systems. The systems can be operated as solidly grounded, low impedance grounded (UK: solidly earthed/resistance earthed), resonant grounded (UK: Petersen Coil) or insulated neutral systems. The multitude of protection functions incorporated into the device enable the user to cover a wide range of applications in the protection of cable and line sections, transformers and motors. The control functions are designed for the control of up to six electrically operated switchgear units equipped with electrical check back signalling located in the bay of a medium voltage substation or a non-complex high voltage station. External auxiliary devices are largely obviated through the integration of binary inputs and power outputs that are independent of auxiliary voltages, by the direct connection option for current and voltage transformers and by the comprehensive interlocking capability. This simplifies handling of the protection and control technology for a switchbay from planning to commissioning.
During operation, the user friendly interface facilitates setting of the device and promotes safe operation of the substation by preventing nonpermissible switching operations. The P139 has the following main functions:
Control functions • Control and monitoring of up to 6 switchgear units • Selection from over 200 predefined bay types or download of customised bay type • Thermal overload protection (with true rms value measurement)
• Bay interlock • Local control and LCD display with a selection between the diagrams and lists of the bay panel, measured value panel and signal panel.
Protection functions • Four pole measurement (A, B, C, N) • Definite time overcurrent protection, 3 stages, phase selective • Inverse time overcurrent protection, 1 stage, phase selective • Short circuit direction determination • Protective signalling • Autoreclosing control • Over/underfrequency protection • Directional power protection • Motor protection (with true rms value measurement)

• Unbalance protection • Over/undervoltage protection • Switch-on-to-fault protection • Circuit breaker failure protection • Ground fault direction determination using steady state values • Transient ground fault direction determination (optional) • Measuring circuit monitoring • Limit value monitoring • Programmable scheme logic. All main functions are individually configurable and can be disabled or enabled by the user as desired. By means of a straight forward configuration procedure, the user can adapt the device flexibly to the scope of protection required in each particular application. Due to the powerful, freely configurable logic of the device, special applications can be accommodated.
In addition to the features listed above, as well as comprehensive self monitoring, the following global functions are available in the P139:
The maximum configuration of binary inputs and outputs provide the signalling of 10 switchgears whereas 6 of them are controllable.
• Parameter subset selection (4 alternative setting groups)
The nominal voltage range of the optical coupler inputs is 24 to 250V dc without internal switching.
• Operating data recording (time tagged signal logging) • Overload data acquisition • Overload recording (time tagged signal logging) • Ground fault data acquisition • Ground fault recording (time tagged signal logging) • Measured fault data
The auxiliary voltage input for the power supply is a wide range design with a nominal voltage range of 48 to 250V dc and 100 to 230V ac. An additional version is available for the lower nominal voltage range of 24V dc. All output relays are suitable for both signals and trip duties.
• Fault recording (time tagged signal logging together with disturbance recording of the three phase currents, residual current, three phase-ground voltages and the neutral displacement voltage).
Control and display
The P139 is of modular design. The pluggable modules are housed in a robust aluminium case and electrically connected via an analogue and a digital bus printed circuit board.
• Communication interface (optional).
The P139 has the following inputs and outputs: • 4 current measuring inputs • 4 voltage measuring inputs • 8 or 14 additional output relays with freely configurable function assignment for individual control or protection applications
• Local control panel • 17 LED indicators, 12 of which allow freely configurable function assignment • PC interface
Information exchange is via the local control panel, PC interface and the optional communication interface. The communication interface conforms alternatively to IEC 60870-5-103, IEC 60870-5101, DNP3.0 or MODBUS. Using this information interface, the P139 can be integrated into a substation control system.
Main functions Main functions are autonomous function groups and can be individually configured or disabled to suit a particular application. Function groups that are not required and have been disabled by the user are masked completely (except for the configuration parameter) and functional support is withdrawn from such groups. This concept permits an extensive scope of functions and universal application of the device in a single design version, while at the same time providing for a clear and straight forward setting procedure and adaptation to the protection and control task under consideration. Control functions For the acquisition of switchgear positions, the P139 uses up to 20 binary inputs for the signalling of up to ten two-pole switching positions and up to twelve binary outputs for controlling of up to six switchgear. The acquisition of further binary inputs is in the form of single-pole operating signals; they are processed in accordance with their significance for the substation (circuit breaker readiness, for example). For each switchgear input and each free input a separate debounce and chatter time may be set. For the acquisition of a binary count, a binary input may be configured. In the event of loss of operating voltage, the count is stored. Upon the following start-up of the unit, counting is continued with the stored value as initial value.
• 6 binary signal inputs (optical couplers) and 6 output relays for the control for 3 switching devices or • 12 binary signal inputs (optical couplers) and 12 output relays for the control of 6 switching devices
The P139 issues switching command outputs with the integration of switching readiness and permissibility tests; subsequently the P139 monitors the intermediate position times of the switchgear units. If a switchgear malfunction is detected, this fact will be indicated (eg. By an appropiately configured LED indicator).
• 4, 8 or 28 additional binary signal inputs (optical couplers) with freely configurable function assignment for individual control or protection signals
3
Before a switching command output is executed, the interlocking logic of the P139 will check whether the new switchgear unit state corresponds to a permissible bay or substation topology. The interlock logic is set out for each bay in the default setting as bay interlock with and without station interlock. By means of a straight forward parameter setting procedure, the interlocking equations can be adapted to the prevailing bay and substation topology. The presentation and functioning of the interlocking system correspond to those of the programmable logic. For integration of the P139 into an integrated control system, the equations for the bay interlock with station interlock form the basis of interlock checking. Without integration into the substation control system, the bay interlock without station interlock is used in interlock checking; external ring feeders may be included in the interlocking logic. If the bay or station topology (as applicable) is permissible then the switching command is issued. If a nonpermissible state would result from the switching operation then the switching command is rejected and a signal to this effect is issued. If the bay type does not require all binary outputs then the remaining outputs are available for free configuration. In addition to the switching command output, a triggering of binary outputs by continuous commands is possible.

Definite time overcurrent protection The definite time overcurrent protection (DTOC) operates on the basis of a four-pole measurement (A,B,C,N) with separate evaluation of the three phase currents and the residual current. Three stages each are provided for the two measuring systems. Each of the stages operates with phase selective starting. The timer stages measuring in the residual path affect the general starting signal. This effect can be suppressed if desired. Starting of the phase current stage I> can be stabilised under inrush conditions if desired. The ratio of the second harmonic component of the phase currents to the fundamental wave serves as the criterion. This stabilisation is either phase selective or effective across

all three phases depending on the chosen setting. The phase current stages I>> and I>>> are never affected by this stabilisation procedure. Intermittent startings of the residual current stage IN> can be accumulated over time by means of a settable hold time. If the accumulated starting times reach the trip limit value (which is also adjustable by setting) then a trip with selective signaling ensues. Additionally, the operate values of all overcurrent stages can be set as dynamic parameters. For a settable hold time, switching to the dynamic operate values can be done via an external signal. Once the hold time has elapsed, the static operate values are reinstated.
Inverse time overcurrent protection The inverse time overcurrent protection operates on the basis of a four-pole measurement (A,B,C,N) just as the DTOC protection does. Additionally, however, the negative sequence current is determined from the filtered fundamental wave of the three phase currents. The three phase currents, the negative sequence and residual current are evaluated in separate, single stage measuring systems. The effect on the general starting signal of the stages measuring in the residual path and in the negative sequence system, respectively, can be suppressed if desired. For the individual measuring systems, the user can select from a multitude of tripping characteristics (see the table below). Starting of the phase current stage and the negative sequence current stage can be stabilised under inrush conditions if desired. The ratio of the second harmonic component of the phase currents to the fundamental wave serves as the criterion. This stabilisation is either phase selective or effective across all three phases depending on the chosen setting. The negative sequence current stage is subject to all phase current stabilisations. Intermittent startings of the phase, negative sequence or residual current stage can be accumulated
on the basis of the set tripping characteristic by means of a settable hold time. Tripping is also performed in accordance with the relevant tripping characteristic. Additionally, the operate values of all overcurrent stages can be set as dynamic parameters. For a settable hold time, switching to the dynamic operate values can be done via an external signal. Once the hold time has elapsed, the static operate values are reinstated. Short circuit direction determination Due to the short circuit direction determination function, the P139 can be used as a directional time overcurrent protection device. For each overcurrent timer stage the user may select whether the stage shall be forward directional, backward directional or nondirectional. Direction determination is performed in separate measuring systems for the phase current and residual current timer stages, respectively. In the direction-measuring system for the phase current timer stages, the phase-to-phase voltage opposite to the selected phase current is used for direction determination as a function of the type of fault, and an optimum characteristic angle is employed (as shown in the table below).
In the direction measuring system for the residual current timer stages, direction is determined using the internally computed neutral displacement voltage; the characteristic angle is adjustable taking account of the various neutral point treatments in the system. The direction measuring system for the residual current timer stages is not enabled until a set value for neutral displacement voltage is exceeded. The user may select whether the triggering preorientation for a non-enabled direction measuring system for residual current timer stages shall be blocked in the event of phase current starting. Protective signaling Protective signaling can be used in conjunction with short circuit direction determination. For this purpose the protection devices must be suitably connected by pilot wires on both ends of the line section to be protected. The user may select whether teleprotection will be controlled by the direction measuring system of the phase current timer stages only, by the direction measuring system of the residual current timer stages only, or by the direction measuring systems of the phase current and residual current timer stages. For protection devices on the infeed side of radial networks, teleprotection can also be controlled without the short-circuit direction determination function.

Auto reclosure control The auto reclosing control (ARC) operates in three phase mode. ARC cycles with a high-speed reclosure (HSR) and multiple (up to nine) subsequent time delay reclosures (TDR) are possible. Reclosuring cycles without prior HSR is possible. For special applications, tripping prior to an HSR or TDR can be delayed. HSR and TDR reclosures are counted and signaled separately. A test HSR can be triggered via any of the unit’s interfaces. Over/underfrequency protection Over/underfrequency protection has four stages. Each of these can be operated in one of the following modes: • Over/underfrequency monitoring • Over/underfrequency monitoring combined with differential frequency gradient monitoring (df/dt) for system decoupling applications
• Over/underfrequency monitoring combined with medium frequency gradient monitoring • (∆f/∆t) for load shedding applications Directional power protection The directional power protection monitors exceeding the active and reactive power limt, a power drop and the reversal of direction at unsymmetrically operated lines. Evaluation of the power is performed using the fundamental wave of the phase voltages and of the neutral displacement voltage. Motor protection For the protection of directly switched h.v. induction motors with thermally critical rotor, the following specially matched protection functions are provided: • Recognition of operating mode • Rotor overload protection using a thermal motor replica • Choice of reciprocally quadratic or logarithmic tripping characteristic
6
Thermal overload protection Using this function, thermal overload protection for lines, transformers and stator windings of HV motors can be realised. The highest of the three phase currents serves to track a first order thermal replica according to IEC 60255-8. The tripping time is determined by the set thermal time constant τ of the protected object and the set tripping level Θtrip depending on the accumulated thermal load Θp: I 2

A warning signal can be issued in accordance with the set warning level Θwarning.
Unbalance protection
Switch-on-to-fault protection
The negative sequence current is determined from the filtered fundamental wave of the three phase currents. The evaluation of the negative sequence current is performed in two time overcurrent stages with definite time delay.
Closing of a circuit breaker might inadvertently lead to a short circuit fault due to a maintenance ground clamp not yet removed, for example.
Over/undervoltage protection The over/undervoltage time protection function evaluates the fundamental wave of the phase voltages and neutral displacement voltage, as well as the positive sequence voltage and negative sequence voltage obtained from the fundamental wave of the three phase-ground voltages. Two definite time delay overvoltage stages each are provided for evaluation of the neutral displacement voltage and negative sequence voltage. Two additional definite time delay undervoltage stages each are provided for evaluation of the phase voltages and positive sequence voltage. Phase voltage evaluation can be performed using either the phase-phase voltages or the phase-ground voltages as desired. For evaluating the neutral displacement voltage, the user may choose between the neutral displacement voltage formed internally from the three phase-ground voltages and the neutral displacement voltage formed externally (from the open delta winding of the voltage transformer, for example) via the fourth voltage measuring input.
The function ‘switch-on-to-fault protection’ provides for an undelayed protective tripping during a settable time after a manual close command has been issued. Depending on the operating mode, a trip command with initialisation of the fault detection logic results. Circuit breaker failure protection With the trip command, a timer stage is started for the monitoring of the circuit breaker action. If the timer elapses due to the persistence of the general starting, a ‘circuit breaker failure’ signal is issued. This serves to issue a second trip command (retrip) or, according to the users choice, to trip neighbouring protection device (upstream breaker). The input of a ‘circuit breaker failure’ signal via an appropriately configured binary input while the general starting persists, effects an undelayed trip command. Ground fault direction determination using steady state values The ground fault direction is determined by evaluating the neutral displacement voltage (eg. from the open delta winding of the voltage transformer) and the residual current (eg. from a core balance or window type current transformer). The directional characteristic can be set to suit the method of system grounding (cos ϕ measured for Petersen Coil and sin ϕ circuit for insulated neutral).
7
In the cos ϕ circuit, the adjustable sector angle also has an effect so that faulty direction decisions (resulting, for instance, from the phase angle error of the current and voltage transformers) can be suppressed effectively. Operate sensitivity and sector angle can be set separately for the forward and backward direction, respectively. Alternatively, an evaluation based on current only can be performed. In this case, only the magnitude of the filtered residual current is used as ground fault criterion. Both procedures operate with either the filtered fundamental or the fifth harmonic component in accordance with the chosen setting. Transient ground fault direction determination (optional) The ground fault direction is determined by evaluating the neutral displacement voltage, calculated from the three phaseground voltages and the neutral current on the basis of the transient ground fault measuring procedure. The direction decision is latched. The user may select either manual or automatic resetting after a set time delay. Measured data output The protection device provides the options of operating data output and fault data output. The user can select an output in BCD-coded form through relay contacts or an output in analogue form as load independent current (0 to 20 mA). For an output in BCD-coded form, an appropriate number of free output relays need to be available. For the current output, a special analogue I/O module is required.
Measuring circuit monitoring
Programmable logic
Clock synchronisation
Measuring circuit monitoring includes the monitoring of the phase currents and phase-phase voltages.
User configurable logic enables the user to set-up logic operations on binary signals within a framework of Boolean equations. By means of a straightforward configuration procedure, any of the protection device signals can be linked by logic ‘OR’ or ‘AND’ operations with the possibility of additional negation operations.
The devices incorporate an internal clock with a resolution of 1ms.
Phase current monitoring is based on the principle of maximum allowable magnitude unbalance, whereby the arithmetic difference between the maximum and minimum phase currents, as referred to the maximum phase current, is compared to the set operate value. Even with an economy type CT connection (CTs in only two phases) it is possible to monitor the phase currents given appropriate settings. Phase-phase voltage monitoring is based on a plausibility check involving the phase currents. If a low current threshold setting is exceeded by at least one phase current, the three phase-phase voltages are monitored for a set minimum level. In addition to magnitude monitoring, phase sequence monitoring of the phasephase voltages may be activated. Limit monitoring A multitude of currents, voltages and the measured temperature are monitored to aid operation of the protected line. This function is not intended to be used for protection purposes, as it has an inherent one second delay. For example, for the 3-phase currents, the phase-ground voltages and the phase-phase voltages the highest and lowest value is determined. These are evaluated using an operate value and time delay set by the user. Thereby, these currents and voltages can be monitored for exceeding an upper limit or falling below a lower limit.
The output signal of an equation can be fed into a further, higher order equation as an input signal, thus leading to a set of interlinked Boolean equations. The output signal of each equation is fed to a separate timer stage with two timer elements each and a choice of operating modes. Thus the output signal of each equation can be assigned a freely configurable time characteristic. The two output signals of each equation can be configured to each available input signal after logic OR linking. The user configurable logic function is then able to influence the individual functions without external wiring (block, reset, trigger, for example). Via non-storable continuous signals, monostable trigger signals and bistable stored setting/resetting signals, the Boolean equations can be controlled externally via any of the device’s interfaces.
Global functions Functions operating globally allow the adaptation of the device’s interfaces to the protected power system, offer support during commissioning and testing, providing continuously updated information on the operation, as well as valuable analysis results following events in the protected system.
8
All events are time tagged based on this clock, entered in the recording memory appropriate to their significance and signalled via the communication interface. Alternatively, two external synchronisation signals can be used according to the selected communication protocol: using one of the protocols MODBUS, DNP3.0, IEC 60870-5-103 or IEC 60870-5-101 the device will be synchronised by a time telegram from a higher level substation control system or in any other case, it will be synchronised using the IRIG-B signal input. The internal clock will then be adjusted accordingly and operate with an accuracy of ±10ms if synchronised via protocol and ±1ms if synchronised via IRIG-B signal. Parameter subset selection The function parameters for setting the protection functions are, to a large extent, stored in four independent parameter subsets. Switching between these alternative setting groups is readily achieved via any of the device´s interfaces. Operating data recording For the continuous recording of processes in system operation or of events, non-volatile ring memory entries are provided. The relevant signals, each fully tagged with date and time at signal start and signal end, are entered in chronological sequence. Included are control actions such as enabling or disabling of functions as well as local control triggering for testing and resetting. The onset and end of events in the network, as far as these represent a deviation from normal operation (overload, ground fault or short circuit, for example) are recorded.
Overload data acquisition
Ground fault recording
Fault recording
Overload situations in the network represent a deviation from normal system operation and can be permitted for a brief period only. The overload protection functions enabled in the protection and control units recognise overload situations in the system and provide for acquisition of overload data such as the magnitude of the overload current, the relative heating during the overload situation and its duration.
While a ground fault condition persists in the power system, the relevant signals, each fully tagged with date and time at signal start and signal end, are entered into a non-volatile memory in chronological sequence.
Fault recording comprises event and disturbance recording along with the stored fault measurands. While a fault condition persists in the power system, the relevant signals, each fully tagged with date and time at signal start and signal end, are entered into a non-volatile memory in chronological sequence.
Overload recording While an overload condition persists in the network, the relevant signals, each fully tagged with date and time at signal start and signal end, are entered into a non-volatile memory in chronological sequence. The measured overload data, fully tagged with the date and time of acquisition, are also entered. Up to eight overload situations can be recorded. If more than eight overload situations occur without interim memory clearance then the oldest overload recording is overwritten. Ground fault data acquisition While a ground fault in a network with isolated neutral or resonant grounding represents a system fault, it is usually nevertheless possible, in the first instance, to continue system operation without restrictions. The ground fault determination functions enabled in the protection device recognise ground faults in the system and provide for the acquisition of the associated ground fault data such as, the magnitude of the neutral displacement voltage and the ground fault duration.
The measured ground fault data, fully tagged with the date and time of acquisition, are also entered. Up to eight ground faults can be recorded. If more than eight ground faults occur without interim memory clearance then the oldest ground fault recording is overwritten. Fault data acquisition A short circuit within the network is described as a fault. The short circuit protection functions enabled in the devices recognise short circuits within the system and trigger acquisition of the associated measured fault data such as, the magnitude of the short circuit current and the fault duration. As acquisition time, either the end of the fault or the start of the trip command can be specified by the user. Triggering via an external signal is also possible. The acquisition of the measured fault data is performed in the measuring loop selected by the protective device and provides impedances and reactances as well as current, voltage and angle values. The fault distance is determined from the measured short circuit reactance and is read out with reference to the set 100% value of the protected line section. The fault location is output either with each general starting or only with a general starting accompanied by a trip (according to the user’s choice).
9
The measured fault data, fully tagged with the date and time of acquisition, are also entered. Furthermore, the sampled values of all analogue input variables such as phase currents, neutral current, phase-ground voltages and neutral displacement voltage are recorded during a fault. Up to eight faults can be recorded. If more than eight faults occur without interim memory clearance then the oldest fault recording is overwritten. Self monitoring Comprehensive self monitoring procedures within the devices ensure that internal hardware or software errors are detected and do not cause malfunctions of the protective devices. As the auxiliary voltage is turned on, a functional test is carried out. Cyclic self monitoring tests are run during operation. If test results deviate from the default value then the corresponding signal is entered into the non-volatile monitoring signal memory. The result of the fault diagnosis determines whether a blocking of the protection device will occur or whether a warning only is issued.
Control All data required for operation of the protection and control unit are entered from the integrated local control panel. Data important for system management is also read out from here. The following tasks can be handled via the local control panel: • Control of switchgear units • Readout and modification of settings • Readout of cyclically updated measured operating data and state signals

• Readout of operating data logs and of monitoring signal logs • Readout of event logs (after overload situations, ground faults or short circuits in the power system) • Resetting of the unit and triggering of further control functions designed to support testing and commissioning tasks The local control panel shown in Figure 2 comprises the local control elements and functions described below. Display (1) The integrated local control panel has an LCD display with 16 x 21 alphanumeric characters (128 x 128 pixels). 17 LED indicators are provided for signal display. (2) 5 LED indicators are permanently assigned to signals. (3) The remaining 12 LED indicators are available for free assignment by the user. A separate adhesive label is provided for user defined labeling of these LED indicators according to the chosen configuration.

Menu tree (4) By pressing the cursor keys and guided by the LCD display, the user moves within a plain text menu. All setting parameters and measured variables as well as all local control functions are arranged in this menu which is standardised for all system devices. Changes to the settings can be prepared and confirmed by means of the ENTER key which also serves to trigger local control functions. In the event of erroneous entries, exit from the EDIT MODE with rejection of the entries is possible at any time by means of the CLEAR key . When the EDIT MODE is not activated, pressing the CLEAR key has the effect of resetting the indications. Pressing the READ key provides direct access to a preselected point in the menu. Switchgear control (5) The control of switching devices from the local control panel can only be done via the bay panel. Switchgear units can be controlled from the local control panel provided that the device has been set to ‘local control’.

This setting may be selected either via the password protected local/remote key or via an external key switch. Once the intended switching device has been selected with the help of the selection key , the switching device may then be controlled via the close key or open key . Pressing the page key results in leaving the display of the bay or the menu tree and switching to the panel display mode. The panel type being displayed may be switched by pressing the page key consecutively. From the panel display, the user can return to the menu tree display at any time by pressing the enter key. Device identification, ports (6) The upper covering flap is labelled with the device type designation. Located under the flap is the type identification label with information on the order number, serial number and the nominal electrical values.
Password protection Access barriers protect the enter mode in order to guard against inadvertent or unauthorised changing of parameters or triggering of control functions
(7) Located under the lower covering flap is the serial interface for connecting a PC. (8) To prevent unauthorized opening of the lower flap, it can be sealed using the attached eyelets. Display panels With the help of the display panels, the user is able to carry out a quick and up to date check of the state of the bay. The device provides the following display panels:
On the bay panel the selected bay is displayed as a single pole equivalent network (single line diagram) with the updated switchgear states. This panel is always displayed following startup or after a defined period of time after the most recent local control action. Moreover, ancillary information such as the position of the remote/local switch, the operating state of the interlock functions and (optionally) a measured value are displayed as text and bar displays.
Selected measured values are displayed on the measured value panels. The type of measured values shown (such as measured operating data or measured fault values) will depend on the prevailing conditions in the substation. Priority increases from normal operation to operation under overload conditions, operation during a ground fault and finally to operation following a short circuit in the system. The measured value sequence in the measured value panel is user configurable. The signal panel displays the most recent events such as the opening of a witchgear unit. A list presentation of the operating data recording complete with time tagging is displayed.

Mechanical design
Processor module P
Bus modules B
The device is supplied in two case designs.
The processor module performs the analogue/digital conversion of the measured variables as well as all digital processing tasks.
Bus modules are printed circuit boards (PCBs) without any active components. They provide the electrical connection between the other modules. Two types of bus modules are used, namely the analogue and the digital bus PCB.
• Surface mounting case • Flush mounting case With both case designs, connection is via threaded terminal ends. Flush mounting cases - taking into account the differing case widths can be combined to form a complete 19” mounting rack. Figure 4 shows the modular hardware structure of the device. The plug-in modules can be combined to suit individual requirements. During each startup the number and type of fitted modules are identified and checked for compliance with the permissible configurations.
