A novel wind turbine simulator for wind energy conversion systems using an permanent magnet synchronous motor

A wind turbine simulator (WTS) for wind energy conversion systems has been developed with a view to design, evaluate, and test of actual wind turbine (WT) drive trains including generators, transmissions, power-electronic converters and controllers. The simulator consists of a 11.5-kW permanent magnet synchronous motor (PMSM) which drives a generator and real-time control software. In this simulator, DSP, a PC interfaced to LAB Windows I/O board, and an permanent magnet synchronous motor are used instead of a real wind turbine to supply shaft torque. The torque characteristic of real wind turbine use 6th order polynomial expression to represented, then according to a given wind speed and rotation speed of PMSM, the theoretical shaft torque of a real wind turbine is obtained. The experimental results of the proposed simulator show that this scheme is viable and accurate. This paper reports the operating principles, theoretical analyses, and test results of this wind turbine simulator.
