PowerFactory offers intrinsic DSL 2-dimensional approximation functions: lapprox2 and sapprox2. The attached project contains two DSL models for these two functions. The Common Models is stored inside…

There are several possibilities to calculate the initial conditions. Consider the example y=a*u+b, where y is the output and u the input signal of the model. The initial value of y is known (=0),…
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…
In the attached example, a 20Mvar STATCOM provides dynamic reactive power compensation for a set of motors connected to a weak network. The study case "Fault Stability Simulation (RMS)"…
The order of the signals defined in a slot and block definition is not relevant for the model. PowerFactory doesn't assign the signals by order, but it does it using the names. Therefore the name is…

Although both look very similar, there is an important difference between the frame and the block diagram. The frame does consist of slots and signals connecting them. In the slots only the inputs and…

The slots in the standard frames are predefined slots for the different elements a synchronous machine controller may have, i.e. the element Power System Stabilizer (ElmPss), etc. The names of the…
In the attached example a random signal is generated using the sample and hold noise generator (ElmNoise) within a DSL model. The generated random signal is defined to change every 1/Frequency…
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 a counter is implemented in DSL using the event function. This function creates in this case a parameter event over the same DSL model every time the input signal changes sign…
