How can I control the power of a 3-phase load in a dynamic simulation using an external file?

Dynamic Simulation

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 the Composite Model for Load Measurement.

The Composite Model frame connects the first two outputs of the file (y1, y2) to the active power input signal Pext and the reactive power input signal Qext of the load model. The load flow data of the load has to be adapted to the values of the measurement file. The online help explains the use of measurement files, refer to the Measurement File (ElmFile) technical reference.
