How can I execute a calculation command in all the study cases?

Find attached in the proejct (ExecuteCalculation.pfd) a DPL (DIgSILENT Programming Language) script that performs the following tasks: Activation of the study cases, one by one. Search and execution…

How can I adjust the tap positions of a 3-winding transformer during the simulation?

To change the tap position of a 3-winding transformer during a simulation define a parameter event (EvtParam) using the appropriate variable: e:nntap_int_h which corresponds to the tap-position HV…

How can I simulate a load event?

To simulate a load event you have to use the EvtLod. The load event works as follows:1. Incremental change Certain percentage of current value, P = P + P*dP/100 (same for Q)2. Absolute change Absolute…

How can I switch on and off a switch or element during a dynamic simulation?

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…

How can I change the voltage set point of an External Source to simulate a voltage drop?

It is not possible to change the voltage set point of an external grid during a simulation. The work around is to replace the external grid by an AC voltage source (ElmVac) and then use one of the…

Do you have an example on capacitor switching?

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…

Do you have an example of modelling a lightning strike on overhead line?

The following example shows how a lighting strike on an overhead line can be modelled in PowerFactory. The network model comprises a small part of a substation and the overhead line. The overhead line…

How can I create events based on a breaker status?

The attached project shows how events can be created based on the status of the breaker. Please note that this works only if the breaker is set to "detailed for calculation". Else the breaker may be…
