An example is attached, where the current source is controlled via a DSL block. Three different possibilities are included in the example. Import the project in PowerFactory and run an EMT Simulation.…
Refer to attached project, in which a DSL block definition "PLL DSOGI EMT 3PH" contains this functionality. Along with other phase-locked loop (PLL) topologies, the DSOGI (double second order…
The attached project shows the energisation of the electrical grid and the active power load pick up with the voltage source converter (VSC) in EMT simulation. The DC capacitor is charged through a…
The idea of the initialisation is to preset the internal model signals by the results of an initial load flow. The key point is to first check for each DSL-model, which inputs/outputs are known and…
You will need to perform an EMT-type simulation for this purpose. To replicate the fault on the cable insulation, the cable must be explictly divided in two sections at the point where the faulty…
If you want to simulate the synchronisation of two different systems, you can model and simulate both systems as separate networks. After some seconds you can then connect them with a circuit breaker…
To model the initial conditions (voltage) of a capacitor bank, you should use a "parameter event" (SetParam) on the variables "uC_a", "uC_b", "uC_c" (signals of the "ElmShnt"). Please find attached an…
In the following example the switching in of a shunt capacitor is demonstrated (via an EMT-Simulation), with focus on the resulting capacitor inrush currents. The network model comprises a 6 kV…
Studies involving WAMS (Wide Area Measurement System) and PMU (Phase Measurement Units) are typically executed with RMS simulation as it is the faster than EMT simulation when dealing with larger…
In the provided PowerFactory project, a single phase line-to-ground fault in the middle of an overhead line can be analysed using EMT simulation. The simple network model contains a 110 kV overhead…
