POWER LOSSES IN A WIND POWER PLANT WITH MAXIMUM POWER POINT TRACKING AND VECTOR CONTROL OF A SYNCHRONOUS GENERATOR

Ensuring the optimal speed of rotation of the turbine, at which the maximum electric power is extracted from the wind energy, is achievable using the maximum power point tracking and vector control of the synchronous generator. The mechanical losses in the gearbox and in the synchronous machine are determined, the steel losses in the synchronous machine and the switching losses in the voltage source inverter are taken into account. The dependences of the efficiency of a gearbox, a synchronous machine, a voltage source inverter and the overall efficiency of a wind power plant on the speed of rotation of a wind turbine rotor are obtained.
