A relevant example is provided in the attached project. Please refer to the attached pdf document for a description of the model aggregation principles.…
There are many definitions of coincidence available from different publishers and communities [1]. In most cases, the data is only available or published as a curve on a graph, making it difficult…
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…
To simulate the charging behaviour of electric vehicles in PowerFactory the template “DIgSILENT Electric Vehicle” from the global library can be used. This is done by using a QDSL (Quasi-Dynamic…

According to VDE/IEC in standard system fed directly from generators without transformer units, the corrected generator impedance defined in following equation has to be used. Z_GK = K_G x Z_G = K_G x…
An UPFC (Unified Power Flow Controller) is a FACTS (Flexible AC Transmission System) device, which consists of two VSCs (Voltage-Sourced Converters). The VSCs are interconnected with each other on…
This can be defined in the load-flow page of the transformer. The attached example shows how to use a phase-shift transformer to control the active power shared between several transformers feeding a…

The example attached includes a measurement file drive in a 3-phase load. Import the project, save the data file loadmeas.txt to the hard disk and select this file in the measurement file object of…
In the attached example, the output power of a single-phase load is controlled via an external file element (ElmFile). Import the project, save the text file to the hard disk, and select this file in…
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…
