Developed of Real Time Simulator for Wind Energy Systems

This paper proposes a developed real time simulator for variable speed wind energy system using two devices of dSPACE real time interface (RTI), one of them contains the wind turbine and the other contains the rest of power circuit with the control circuits, due to lake of real model of wind turbine and a permanent magnet synchronous generator. The results of the real time simulation provide that, maximum power generation control technique at the converter of generator side has been achieved, the voltage of DC-link has been kept constant, finally the grid unity power factor has been attained using a simple PI controller cascaded with a hysteresis current controller on the voltage source inverter (VSI) at the grid side. The suggested developed real time simulator design gives more benefits for both research and application of wind energy system whereas the testing in the field is expensive and consuming time.
