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…

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…

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…
Refer to the attached example. In order to understand the interface of the controller with the transformer, the following information needs to be considered: Based on the fact that we consider a…

It is possible to monitor the breaker status in a DSL model. The switches (StaSwitch) that are to be monitored must have the flag "detailed for calculation" enabled. This option is located in the…
Refer to the attached example. It describes an induction generator with the necessary dynamic models. The reactive power is balanced using a switched capacitor. The dynamic models are a shaft model…

An example is provided attached depicting a linear and a non-linear dynamic load model.…
Refer to the attached Digexdyn_Description_and_Example.zip. In PowerFactory the digexdyn interface allows for linking discrete-time models in RMS or EMT simulations: This interface can be used for…
