1. INTRODUCTION The phases phase X within the X Gas Field Development project are designed to process the incoming hydrocarbon fluid by the sub-marine sub marine pipelines. The refinery is located at X Village, about 270 km South East of X city. The Temporary Electrical Power required for phases X Gas Plant shall be supplied from Power Plan Plant of Mobin Mobin Petrochemical Complex through 132kv 132 v underground cable line and a 132kV/33 132kV/33kV,, 100MVA power transformer. Six generators that are connected to the X National grid are assumed to supply electric power through circuit that contains 132kV cable and 13 132/33kV 2/33kV transformer. The temporary supply relay setting and coordination studies are described in this document.
2. SCOPE The objective of this document is to do relay settings and coordination analysis for temporary supply up to the 33KV outgoing to the Gas plant relays that are coordinated by another vendor and made available to us in document VP 6340S 1600 LG 0001 077. 077 The results of this study provide the exact settings of the concerned relays of the temporary supply which must be tuned before commissioning of the plant.

3.2. System Analysis Software PASHA (Power Apparatus and System Homological Analysis), Version 2008,, was used for performing the studies. The software is product of TOM and serving the electrical utilities and the industries for twenty three years worldwide.
3.3. Electrical System Representation 3.3.1. Network Topology Single line diagram of the involving plants are used to produce the study power system. Figure 1 shows hows a view of the overall electrical network represented in the present studies. Gas plant is analyzed and equalized in Appendix I. For the purpose of the equalization, the Gas Plant, single line diagram as represented in drawing DW 6340S 120 1633 0001 is represented in PASHA software. Documents NC 6340S 999 1630 0020, 0020, NC 6340S 999 1630 002 0021 are used to provide the required data. Here, 11 KV motor loads are represented separately based on their dynamic models. Some of 6 KV motor loads are also represented separately based on their dynamic models models. Other 6KV motors and 400 V induction motor loads are summed and represented as equivalent m motor otor loads on their corresponding bus bars. Static loads are lumped represented on their appropriate locations. Please refer to appendix I for detailed representation of GAS PLANT electrical systems. Figure 2 shows the electrical network representation whe where re the static and dynamic equivalent of the GAS PLANT is represented inside the network, please see also drawing DW 6340S 550 1600 0002, and DW 6340S 550 1600 0001 000 at the end of this report inside appendix I. The dynamic loads of this plant are represented as equivalent induction motor motors and loads loads.. The parameters of the equivalent induction motors are selected such that the static power requirment and the dynamic behaviour of the load matches those comes from the overall loads and induction motors existing iin n the Gas Plant. Equalization, makes documentation and reportings easiear. The Gas plant equivalent valent is shown in GASEQUAL area in Figure 2. In n fault and relay coordination studies we need to consider the maximum planed and in operation fault level levels and their their contributions in device setting studies. The neighboring factories play important rule in this regard. Therefore, they are included in the representation of the electrical networks as it is shown in Figure 2. In this report the neighboring factories are called External xternal plants plants.. The external plants are represented by their lumped loads equivalence. For these lumped loads 80% motor loads is considered. One incoming transformer of these plants is also considered in the studies. This is because the bus bars o on 20KV or 33KV side of the external plants cannot be closed together. Maximum aximum fault current contribution contributionss of these plants are imposed in their respective board when a bus coupler is closed while one incomer is opened. Therefore all the motor fault contributions contributions to short circuit are congregated in the coupled bus. The external plants are shown in EXTERNAL area in Figure 2.

The existence of the connection of MOBIN MOB power generation plant to X National GRID is also considered. This is shown in Figure 2 in GRID area.. The detailed representation of the X national power grid is already represented in PASHA software elsewhere. The 1990 deck of the 400KV, 230KV, and 132KV of the X network which includes the 63KV of the Esfahan is used to provide the equivalent of th the e power grid as represented in this report. The box RELAY is introduced inside the Gas plant equivalent to consider for the outgoing 33KV relays that feeds the various substations inside the Gas plant. The bahaviour of 33KV relays protecting the 11KV motors motors of the Gas plant is also considered. The selected equivalent motors are intdicated in Figure 2 in 11KV area. As mentioned the equalization is just made to simplify the reporting, the actual 33KV relays behavior is also considered inside the Gas plant but it does not included in the reports.

4. CALCULATION CRITERIA a) PASHA dynamic fault studies and transient stability calculations b) Software PASHA version 2008 c) Calculation procedure for short circuit analysis (i)
Maximum considerable short circuit current is depicted in the analysis
(ii)
Generators saturated reactances are considered in the analysis as the clien clientt request However in dynamic fault studies the actual reactances considering the saturation will be used by PASHA
(iii)
Pre-fault fault voltages are shown in input data table tables and their values depend to load flow results
(iv)
Maximum fault current is attained when six generators connected to the GRID GRID, are supplying the power required for G Gas plant and 33KV Bus Bus-coupler coupler is closed and dual feeding by incomer transformers are not considered (i.e. one incoming circuit is considered) considered).. Since other connected external plants loads and the future reinforcement of the MOBIN generation station are considered, the maximum fault current is obtained when all the external plants are in action.
(v)
Minimum fault current is attained when two generato generators rs are supplying the Gas plant through one temporary circuit that feeds the Gas plant. In this situation a two phase fault in the outgoing 132KV cable can not be cleared by the present relay settings before the trip of MOBIN two generators. The problem can be solved with extra signaling if required required.
(vi)
Therefore, In the above special occasions of L L-L L faults, Minimum is considered with three generators or two generators generators and the GRID in action in the present report.
(vii)
For high set relays and the transformer inrush current consideration the fault is calculated instantaneously. For other relays settings the actual current up to the time of operation of the relays will be considered by software.

5. LOAD FLOW AND FAULT RESULTS Load flow of the network considered is already reported in document NC 6340S 550 1600 0002. 0002 Short circuit analysis of the plant is reported in document NC 6340S 550 1600 000 0003.. For the sake of simplicity of the reviewing of the results, maximum load flows o off the plant and the maximum fault contribution of the plants are shown in the following figures (Figures (Figure 3,, 4 and 5 show the load flow results and Figure 6 and 7 show the fault results results).. Here since PASHA dynamic short circuit study is used for the relay settings, se the short circuit results shown in Figure Figures 6 and 7 outcome the result of using such a method. In document NC 6340S 550 1600 000 0003 3, IEC909 method has been used. There is however a small difference in the result results, s, but the dynamic fault is more reliable reliable for the purpose of relay coordination coordination. Please lease refer to the pa paper pers published in IEEE Transactions on Industrial ndustrial Application pplication: 1-- “A Comparison of Static and Dynamic Short Circuit Analysis Procedures”,1990 pp463 2--“Simulation “Simulation of Protective Relay Performance Under Short Circuit and Transient Swing Conditions” ,1990, pp1108 Also please note that document NC 6340S 999 1630 0020 short circuit study is based on 1314MVA maximum Short Circuit Capacity (SCC) of the incoming supply. This would not be the ccase ase for 100MVA, 10% transformer used in the temporary incoming supply.

7. RELAY SETTINGS The current practice of relay coordination and settings which are reported in IEC standard standards and other practical text books are adopted in this report to obtain the best possible function of the relays during the operation. Both short circuit studies and transient stability studies have been performed and the relays actions were observed to act iin n desired performance. The manual of the manufacturer are reviewed in order to consider the special function and treatment of the relays. The 33KV outgoing relays including the 33KV bus tie relay coordinated in document VP 6340S 1600 LG 0001 077 are the basis basis of the incoming relay relays settings that are reported in the present document. Note that; that the earth faults fault 51 1G and 50G of the bus tie have some settings setting in the mentioned document, but its core balance CT is not specified. Therefore, with reference to document DWG VP 6340S 1600 LG 0001 077 sheet 12 from 35 35, it is recognized that the earth current obtaines from residual phase currents. currents Therefore, the CT ratio is 2500:1. The setting values (IDMT-SI SI 0.1In , TMS=1 for 51G)) and (I>>1In I>>1In , tI>>0.05 tI for 50G) 50G reported in document VP 6340S 1600 LG 0001 077 for this bus tie can not protect the system againt LG fault; since for LG short circuit current (i.e. 400A 3I0) its operation time is aboutt 14sec which is too high. But this setting settings have not been changed in tthe e present report,, because it is out of the scope of the report. report Note also that;; the phase fault 51 and 50 relays of the bus tie do not have appropriate settings in document VP 6340S 1600 LG 0001 077. 077 The setting values ((IDMT ( IDMT-SI 0.8In In , TMS=1 for 51 51)
and (I>> I>>8In , tI>>0.6 0.6 for
50) 50 can not protect the system even againt three phase fault. Its operatiom time for a three phase fault in even in 33KV busbars is abot 3200msec. which is too high. But this settings settings have not been changed in the th present report, report because use it is out of the scope of the report report. Note also those comments written in section 9 of this report about undervoltage relay settings of document VP 6340S 1600 LG 0001 077. 077 Note also on the comments comment written in section 4, 4, i.e. Minimum fault current in the present document is attained when two generators are supplying the Gas plant through one temporary circuit that feeds the Gas plant. In this situation a two phase fault in the outgoing 132KV cable can not be cleared by the present relay settings before before the trip of MOBIN two generators. The problem can be solved with extra signaling if required.Therefore, required.Therefore, In the above special occasions of L-L L L faults, Minimum is considered with three generators or two generators generators and the GRID in action.

9. TRANSIENT ACTIONS The relays set in section 8 and the relays set by other vendors are all put under investigation, in this section section. 10.1 TRANSIENT ACTION OF THE RELAYS WITH TRANSIENT STABILITY In order to accept the relay action during the fault, the entire network is subjected to the following Transient ransient Stability tability TS (or frequency dynamic FD) scenarios: scenarios
(1) Three phase fault are applied in the 33KV busbars and outgoing lines, lines, and cleared by primary prima protection which are already tuned in document VP 6340S 1600 LG 0001 077, 077, in order to investigate the plant recovery. PASHA considers the relay action automatically in its transient stability and frequency dynamic simulation. Some of the results are sho shown wn in the following sections. sections (2) Three phase fault are applied in the 33KV busbars and outgoing lines, and cleared by back up protection, in order to investigate the plant recovery.
and the switching actions are reported in the followings.
9.1.1
33KV UNDER VOLTAGE RELAY ACTION IN TRANSIENT STABILITY SIMULATION
A fault lasting for 300 msec. long (Starts from 100msec) applied in the external factories in its 20KV substation side. side The TS output results shown in Figure 9 and its table, table, indicate that Under voltage voltage relay (P922) set in document VP 6340S 1600 LG 0001 077 ; (The e setting is 0.8P.U. P.U. and 0.2 sec sec) will operate and disconnects all the outgoing lines and black outs the entire Gas as plant. It is obvious that this relay has not been set properly, since the 300msec long duration fault in the neighboring factory is a usual interruption time considering the relay and circuit breaker actions in these factories. In order to investigate other transient transient runs runs,, the setting settings of under voltage relay set in the mentioned document are inhibited. In fact they are set at 0.7 P.U., 1100 msec. sec. which is our suggestions. However, the responsibility of the action of this relay is out of the scope of the present do document cument.

Under nder voltage, Bus Transfer
Document VP 6340S 1600 LG 0001 077 has tuned undervoltage/overvoltage undervoltage/overvoltage relay for 6KV busbars at 0.8P.U. 0.2sec. and undervoltage for 400V busbars at 0.8P.U. 0.2 sec. These have the same problem as already mentioned in section 7.2. No bus transfer schemes has been recognized and no automatic rest restart has been defined for system loads. Therefore, in the present document we have assumed that all undervoltage relays are inhibited.
9.2 TRANSIENTS CHECKS
The following figures (Figures 10,11,12,13 10,11,12,13 and 14) 14 show the relays action and time of opening of the circuit (Including Cicuit Breaker Intrruption Intr uption time), for a specified three phase fault. Please note that, these are different from those shown in relays action lists reported in section 8 of the present document. Those lists are using short circuit analysis and these are due to transient stability analysis. The latter is more reliable, since all the transient actions of the induction motors, angle diviation of the supply, AVR and Governor actions and many other factors that do not usually consider in short circuit studies will be considered in transient stability runs. For example if you do apply a three phase fault in 20KV of neighboring factory in short circuit analysis, the voltage in 1S11A would be more than 0.9 P.U. (and it does not show the problem already mentioned in section 9.1) 9.1),, while the reality is that; that the voltage in 1S11A will pass below 0.7 P.U. during the induction motors recovery from fault. In all the following figures, we have assumed that some 400V sma smallll induction motors will be disconnected from the system due to their AC contactor action actions.. As indicated before, the undervoltage relays actions in 6KV and 400V of Gas plant have been ignored, ignored, due to their incorrect settings settings. The induction motors switching actions are shown with L/OUT (Lock out) times in these these figures. Also note that the INTERLOCK between upstream and downstream circuit breakers of the temporary supply has not introduced in simulations. In figure 14, although the fault will be cleared in 23 230msec., 0msec., MOBIN generator relays disconnect the supplying generator in 2.106 106sec. sec. This is because we have not considered the Under Voltage and AC contactors of the external plants that the MOBIN generator plant is supplying them. This might not be happened in the real situation. However the consideration of this phenomena is out of the scope of this report. As far as this report is concern, the three phase fault in the 132KV cable is cleared as fast as possible, i.e. 230 msec.

The following figures (Figures 15, 16, 17,18,19,and 17,18 20)) are snapshots of relay operating times (excluding Circuit Breakers opening times) in PASHA protection checking studies studies.. In this section we have used PASHA short cicuit analysis to find the operating times of the relays. They are shown in the figures and iin the lists. In these figures the symbols PH indicate the phase relay action and symbols Ea indicates the earth relay actions. The unit protections protections are checked against operating for inside fault and not to operate for the fault through the devices (outside fault).. The operation and no operation of them are shown in figure 21.

A.I.1 A.I. GAS PLANT ELECTRICAL NETWORK REPRESENTATION
Gas plant single line diagram as represented in drawing DW 6340S 120 1633 0001 is represented in PASHA software. Drawings DW-6340S-550 550-1600-0001 0001,, which is included in the last pages of this appendix, shows the Gas plant electrical network topology as represented in PASHA. Here the type and lengths of cables are also shown. Documents NC 6340S 999 1630 0020 0020, and NC 6340S 999 1630 002 0021 are used to provide the required data. Here, 11 KV moto motorr loads are represented separately based on their dynamic models. Some of 6 KV motor loads are also represented separately based on their dynamic models models. Other 6KV motors and 400 V induction motor loads are summed and represented as equivalent motor loads on their corresponding bus bars. Static loads are lumped represented on their appropriate locations. The tie switched position and the amount of loads are set according to worst condition situation as addressed in document NC 6340S 999 1630 0020 0020.
