Abstract

We have developed a digital real-time simulator of power electronics systems by using MATLAB/SIMULINK. This paper describes the modeling and the calculation accuracy of STATCOM models. Hence the simulator operates at a large time step of 50 μs, in order to improve simulation accuracy, a correction processing is implemented in the STATCOM model. Calculation accuracy of the real time STATCOM model is the same level as EMTDC results. We confirm stable operation of the developed simulator with connecting a commercial real time digital simulator (RTDS).
