There are several reasons for this error message. It is issued when - at PowerFactory startup - no licence is found. * In case you are using a USB dongle licence, please make sure that the USB dongle…
The number of nodes does vary depending on the specific setup when a calculation is executed. For a given instant, you can check the number of nodes by doing the following: - Have a project and…
The attached project shows all three different possibilities the DSL event command offers. The three loads are disconnected by a DSL model. The event is triggered in this case fixed at 2s via the…
The Thevenin and Norton equivalents are characterized by their open-circuit voltage and short circuit current. The inner voltage source of the Thevenin equivalent equals the open circuit voltage,…
