EXERCISE 1 Task Purpose of this exercise is to learn and understand: - TCP-IP communication between PCM 600 and the IED - CAP 531 and SMT tools - On-line library synchronisation between PC and IED Goal of the exercise is to design a configuration from scratch where the IED 670 will behave as an earth-fault relay. The protection device is connected to the line according to the following diagram:

Procedure Procedu re (Overvi (Overview) ew) -

Have a look to the last function block names (ZM etc) you can find in the library:

Press “Cancel” after you have looked at the library. Do “file” / “close all” and then run “Online” / “upload options” to synchronize the CAP 531 function library with the IED function library 2: 2

Eventually you need to run “Reconfigure” from the HMI in order to be sure that you will get the correct hardware information during upload options. “Reconfigure” is found on the HMI under this path: “Settings” / “General settings” / “I/O Modules”  “Reconfigure” Substation Automation & Protection Training SA-T Training, SEP-601

6. Start to do your application conf iguration. Open t he WorkSheet called “ ANALOG_IN” and insert the “ virtual analog input s” 3 for current measurement and for volt age measurement (SMAI)4:

“Virtual analog input” is not the correct technical word, even if it well explains the main purpose of those function blocks. They are called PREPROCESSING BLOCKS. 4 For voltages use the block PR13 (8 ms). For currents use block PR14 (8ms). WHY “8ms blocks” ? Because earth fault protection is a “ 8 ms” function , and it must be served by “ 8 ms” preprocessing blocks! Substation Automation & Protection Training SA-T Training, SEP-601

7. Create following configur ation for Voltage and Current Inputs. Here below you have the configuration:

For voltage inputs we have chosen NOT to physically connect to the device the line 3U0 voltage (open delta transformer). For this reason in the pre-processing block you see “Not used” under input n. 4 of the pre-processing block. When the pre-processing block “sees” that no physical signal is connected to its input n. 4, it calculates the 3U0 voltage from the given inputs n.1, 2 and 3. This signal is sent out from the out signal “AIN”, and we will use it for the connection to disturbance recorder (variable “3Uo_Line (c)” where “c” means computed signal). The same we have done for the residual current in pre-processing block PR14. We intend to calculate the residual current from signals IL1, IL2 and IL3.

Remember the signal ”TYPE” in the pre-processing block. For voltages it must be ”1, for currents it must be ”2”.

The final configuration for pre-processing block will look like this:

We need now to define the variables “FALSE” and “REAL_ZERO”. For this a special SA-T Training, SEP-601

IMPORTANT! THIS CONFIGURATION IS SIMPLIFIED! A LL TRIP SIGNAL S FROM PROTECTION SHOULD OPEN THE CIRCUIT BREAKER THROUGH THE SO CALLED “ TRIP FUNCTION” , THAT WE ARE NOT USING HERE FOR SIMPLICITY! NEVER BYPASS THE TRIP FUNCTION IN A REAL CONFIGURATION!

Your application configuration in CAP 531 is finished now. Notice that, even if a simple one, we have done the following: - definition of virtual voltages and virtual currents (pre-processing blocks, PR) - definition of virual inputs and virtual outputs (SMAI and SMBO blocks) - connection of virtual signals to protection function in order to satisfy our application (directional earth fault protection)

the application configuration has been designed without considering the physical hardware set-up of the device. This will be done later, by using Signal Matrix (SMT). We need now to compile the configuration and write (download) it into the device. 12. Compile the graphic conf iguration and downl oad it (write it) into t he device. Do “File” / “Close All” and then:
