Modeling a Synchronous Generator with Real-Time Hardware

A model of a synchronous generator including saturation and the oscillation of rotor caused by changes in the applied mechanical power is realized on a real-time hardware. Therefore it is possible to build a closed-loop system consisting of an excitation device as device under test and a simulated synchronous generator as test tool, which offers the opportunity for setting-up, testing and designing excitation devices. The model reads the excitation voltage from the excitation device and calculates in real-time the stator voltages and currents as output values depending on the parameters "applied mechanical power" and "voltage of the supply network".
