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…
There are two possibilities to work with user defined variables in a dynamic simulation: Using the option ’User Defined Signal’ included within the PltDataseries. This allows calculation of additional…
In the attached example a ramp modeled in DSL is used to reduce the turbine power pt from its initial value to zero. You also may use a similar block structure to impose a ramp on any other machine…

In the example attached, a Register and a Sample and Hold are included within the model to show their behave. The Sample and Hold stores it's sampled input signal at the output until the next rising…

Refer to the 2 example projects:The first example 'EvtSwitchExt' shows, how to call a switch event (EvtSwitch) out of a DSL model (general model). In this example the switch events are predefinided in…
For load flow calculation, static analysis, the three phase voltages can only be altered by specifying the amplitude and the phase lag in the positive, negative and zero sequence system of the voltage…

For RMS simulations the load type has to be set to 100% dynamic load, this means constant impedance Z. Additionally in the RMS dialogue of the load type the voltage dependency of P and Q can be set.…
The attached example shows how an AC current source (ElmIac) is controlled during a RMS simulation. In the first study case the amplitude and the angle of all phases are equally controlled, requiring…

There are several ways of modelling an SVC system: Using the SVS Interface in PowerFactory: A number of standard controls for SVS are available in the global library. There, you can also find…

A simple moving average discrete time filter is provided for your reference. It can be used for both RMS and EMT type simulations. The register model (ElmReg) could be used to calculate a moving…
