Michael Igel 6 Network Simulation and Diagram Viewer 61 61 ATP Data: Simulation Data ATPDesigner – Design and Simulation of Power Networks Hochschule für Technik und Wirtschaft des Saarlandes University of Applied Sciences Prof. Dr.- Ing. Michael Igel Before Starting the Simulation it is necessary to specify some settings, which are related to the simulation process. Time Overall Length of the Calculated Data in Cycles Prefault Time before a Line Fault occurs dt Sampling Rate of the Data stored in the .PL4 – File Out Repetition of the Test Step, related to CMC Test System Step Number of Calculation Steps between two Samples stored in the .PL4 - File 62 62 ATP Data: Simulation Data ATPDesigner – Design and Simulation of Power Networks Hochschule für Technik und Wirtschaft des Saarlandes University of Applied Sciences Prof. Dr.- Ing. Michael Igel Advantage of dt and Step It is often a must to use a high internal sampling frequency caused by complex and high-sophisticated numerical models e.g. LINE CONSTANTS. On the other hand it is often sufficient to write the sampling values of voltages and currents in the .PL4 – file using a low sampling frequency. Both requirements can be set independent from each other with the both settings dt Step. Example: Testing Protection Relays The typical sampling frequency of protection relays is about 1000Hz. If a test engineer uses e.g. an Omicron CMC Test System, it is sufficient to use an output sampling frequency of about 5000Hz = 0.2ms in the .PL4 – file. Therefore the settings dt should be set to dt = 0.2ms. The internal ATP related sampling frequency can now be set dependend on the requirements of the used numerical models. 63 63 First Calculating Voltages, etc. ATPDesigner – Design and Simulation of Power Networks Hochschule für Technik und Wirtschaft des Saarlandes University of Applied Sciences Prof. Dr.- Ing.
