The protection device is connected to the line according to the following diagram: Procedure (Overview) -Set-up communication parameters to manage TCP-IP communication (ethernet) between PCM 600 and the IED. -Perform and understand the on-line synchronisation (upload options and function selector). -Configure the virtual analog inputs, virtual outpus and the connections to the earth fault relay (CAP531) -Associate physical inputs outputs to the virual signals (SMT) -Set CT and VT data, virtual analog input data, relay data (PST) -Test your design (for instance use On-line Debug (CAP 531) and test equipment). SA-T Training, SEP-6012007-09-05Page 2 of36 ABB AB Power Automation & Substation Vsters - Sweden Training Course SEP-601EXERCISE 1 Substation Automation & Protection Training Procedure (Detailed) 1.Start PCM 600 and create a new project containing one IED 670 terminal (answer that you have no filesat questions from the Wizard). Give to the project the name you wish. Avoid to use spaces in your project1: Insert one IED 670 IEC version 1.1 device under your bay (example is for REL 670):

1 Even if PCM 600 works with spaces, REMEMBER not to use spaces as they are not allowed in IEC 61850 files (SCL files). SA-T Training, SEP-6012007-09-05Page 3 of36 ABB AB Power Automation & Substation Vsters - Sweden Training Course SEP-601EXERCISE 1 Substation Automation & Protection Training The wizard will pop-up: Rename the IED name, to remove SPACES: 2. Set the IP address of the PC to be compatible to the IP address of your device (in the example, the PC IP-address is 10.1.150.99, with Subnet MASK 255.255.255.0) SA-T Training, SEP-6012007-09-05Page 4 of36 ABB AB Power Automation & Substation Vsters - Sweden Training Course SEP-601EXERCISE 1 Substation Automation & Protection Training 3. Check that the PC has contact with the IED by using the PING command (PING 10.1.150.1 and see the answer): SA-T Training, SEP-6012007-09-05Page 5 of36 ABB AB Power Automation & Substation Vsters - Sweden Training Course SEP-601EXERCISE 1 Substation Automation & Protection Training 4. Start Application Configuration (CAP531) for the IED (password is ABB ): 5. UNDERSTANDING UPLOAD OPTIONSand FUNCTION SELECTOR . Insert one (empty) worksheet in CAP 531and call it ANALOG_IN: SA-T Training, SEP-6012007-09-05Page 6 of36 ABB AB Power Automation & Substation Vsters - Sweden Training Course SEP-601EXERCISE 1 Substation Automation & Protection Training Double click on the worksheet to open it. Click somewhere inside the empty worksheet: Try to insert a function block (open the function library available in CAP 531: SA-T Training, SEP-6012007-09-05Page 7 of36 ABB AB Power Automation & Substation Vsters - Sweden Training Course SEP-601EXERCISE 1 Substation Automation & Protection Training Have a look to the lastfunction 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 library2:

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 ModulesReconfigure SA-T Training, SEP-6012007-09-05Page 8 of36 ABB AB Power Automation & Substation Vsters - Sweden Training Course SEP-601EXERCISE 1 Substation Automation & Protection Training at this point, the CAP 531 library has been synchronized to the IED library. Try now to open the ANALOG_IN function block, open the library and verify if the same functions are available. SA-T Training, SEP-6012007-09-05Page 9 of36 ABB AB Power Automation & Substation Vsters - Sweden Training Course SEP-601EXERCISE 1 Substation Automation & Protection Training FUNCTION SELECTOR (SYNCHRONIZING THE HARWARE LIBRARY) Run Edit / Function Selector : SA-T Training, SEP-6012007-09-05Page 10 of36 ABB AB Power Automation & Substation Vsters - Sweden Training Course SEP-601EXERCISE 1 Substation Automation & Protection Training Do now File / Load / Uploaded data: you have now synchronized the hardware library in CAP 531 with hardware set-up of the IED. REMEMBER TO DO SAVE, before you exit from FUNCTION SELECTOR: SA-T Training, SEP-6012007-09-05Page 11 of36 ABB AB Power Automation & Substation Vsters - Sweden Training Course SEP-601EXERCISE 1 Substation Automation & Protection Training at this point you can EXIT from Function Selector window and go back to CAP 531:

SA-T Training, SEP-6012007-09-05Page 12 of36 ABB AB Power Automation & Substation Vsters - Sweden Training Course SEP-601EXERCISE 1 Substation Automation & Protection Training SA-T Training, SEP-6012007-09-05Page 13 of36 ABB AB Power Automation & Substation Vsters - Sweden Training Course SEP-601EXERCISE 1 Substation Automation & Protection Training 6. Start to do your application configuration. Open the WorkSheet called ANALOG_INand insert the virtual analog inputs3 for current measurement and for voltage measurement (SMAI)4:

3 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 msfunction, and it must be served by 8 mspreprocessing blocks! SA-T Training, SEP-6012007-09-05Page 14 of36 ABB AB Power Automation & Substation Vsters - Sweden Training Course SEP-601EXERCISE 1 Substation Automation & Protection Training 7. Create following configuration 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. SA-T Training, SEP-6012007-09-05Page 15 of36 ABB AB Power Automation & Substation Vsters - Sweden Training Course SEP-601EXERCISE 1 Substation Automation & Protection Training 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-6012007-09-05Page 16 of36 ABB AB Power Automation & Substation Vsters - Sweden Training Course SEP-601EXERCISE 1 Substation Automation & Protection Training function block is used called Fixed Signals. Pick-it up from the function library: and assign a fixed value to the variables FALSE (logical zero) and REAL_ZERO (real value =to zero): 8.Close the Worksheet ANALOG_IN and create a new Worksheetcalled PROTECTION : SA-T Training, SEP-6012007-09-05Page 17 of36 ABB AB Power Automation & Substation Vsters - Sweden Training Course SEP-601EXERCISE 1 Substation Automation & Protection Training SA-T Training, SEP-6012007-09-05Page 18 of36 ABB AB Power Automation & Substation Vsters - Sweden Training Course SEP-601EXERCISE 1 Substation Automation & Protection Training 9. Open the Protection Worksheetand insert the Directional Earth Faultfunction. Supply the function block with voltage and current measurements.

draw the following configuration: SA-T Training, SEP-6012007-09-05Page 19 of36 ABB AB Power Automation & Substation Vsters - Sweden Training Course SEP-601EXERCISE 1 Substation Automation & Protection Training 10. Close the Worksheet PROTECTIONand create a new Worksheetcalled V_IO(Virtual Input Outputs): 11. Open the V_IOWorksheet and assign the trip and start signals to a virtual output block, the external blocking signal to a virtual input block. SMBO is the name for the virtual outputs, and SMBI is the name for the virtual inputs. SA-T Training, SEP-6012007-09-05Page 20 of36 ABB AB Power Automation & Substation Vsters - Sweden Training Course SEP-601EXERCISE 1 Substation Automation & Protection Training IMPORTANT! THIS CONFIGURATION IS SIMPLIFIED! ALL TRIP SIGNALS 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 configuration and download it (write it) into the device. Do File / Close All and then: Notice that there are no stars close to the Worksheet names, because the application SA-T Training, SEP-6012007-09-05Page 21 of36 ABB AB Power Automation & Substation Vsters - Sweden Training Course SEP-601EXERCISE 1 Substation Automation & Protection Training configuration is compiled: 13.Download (write) the configuration into the IED: SA-T Training, SEP-6012007-09-05Page 22 of36 ABB AB Power Automation & Substation Vsters - Sweden Training Course SEP-601EXERCISE 1 Substation Automation & Protection Training 14.Exit from CAP 531 ( File/ Exit ) and go back to PCM600: SA-T Training, SEP-6012007-09-05Page 23 of36 ABB AB Power Automation & Substation Vsters - Sweden Training Course SEP-601EXERCISE 1 Substation Automation & Protection Training 15.Open SMT for your IED: 16. Associate physical CTs and VTs to VirtualCTs and VTs. Write (download) the SMT configuration into the IED: SA-T Training, SEP-6012007-09-05Page 24 of36 ABB AB Power Automation & Substation Vsters - Sweden Training Course SEP-601EXERCISE 1 Substation Automation & Protection Training SA-T Training, SEP-6012007-09-05Page 25 of36 ABB AB Power Automation & Substation Vsters - Sweden Training Course SEP-601EXERCISE 1 Substation Automation & Protection Training 17. Associate the virtual blocking input to a physical binary input. 18. Associate physical binary outputs to the virtual ones. Assign also the HMI LEDs. 19.Write (download) the SMT information into the IED. Exit from Signal Matrix and go back to PCM 600. SA-T Training, SEP-6012007-09-05Page 26 of36 ABB AB Power Automation & Substation Vsters - Sweden Training Course SEP-601EXERCISE 1 Substation Automation & Protection Training 20. In the next steps we will use Parameter Setting (PST) to set all the function blocks involved in the application configuration. Open Parameter Setting Tool (PST): Setting of CTs and VTs5 :

5 This is very important, because all function blocks in IED 670 think in primary values. Settings are also in SA-T Training, SEP-6012007-09-05Page 27 of36 ABB AB Power Automation & Substation Vsters - Sweden Training Course SEP-601EXERCISE 1 Substation Automation & Protection Training Acording to what we have done in SMT and to the single line diagram at the beginning of the exercise: write (download) the CT and VT settings into the IED: primary values, so CT and VT data are absolutely the first settngs that we should think about. SA-T Training, SEP-6012007-09-05Page 28 of36 ABB AB Power Automation & Substation Vsters - Sweden Training Course SEP-601EXERCISE 1 Substation Automation & Protection Training Pre-processing block settings: J ust have a look at the actual settings available in PST for the preprocessing blocks: SA-T Training, SEP-6012007-09-05Page 29 of36 ABB AB Power Automation & Substation Vsters - Sweden Training Course SEP-601EXERCISE 1 Substation Automation & Protection Training you can see that the signal names (comments) you have defined in CAP 531, are NOT THERE in PST! But you have downloaded the configuration in the IED, so to get that information you should now do read from PST: SA-T Training, SEP-6012007-09-05Page 30 of36 ABB AB Power Automation & Substation Vsters - Sweden Training Course SEP-601EXERCISE 1 Substation Automation & Protection Training We need to change the base value for the pre-processing blocks. Other settings can be kept as default because we are not going to do any frequency tracking algorithm but just require the Fourier Transform to be centered on fixed frequency (50 Hz or 60 Hz): SA-T Training, SEP-6012007-09-05Page 31 of36 ABB AB Power Automation & Substation Vsters - Sweden Training Course SEP-601EXERCISE 1 Substation Automation & Protection Training Write the settings for pre-processing blocks into the IED.
