摘要
For the problem of hack-to-hack PWM converter open circuit fault in wind power generation system, the operation principle and fault classification standard of MN' converter arc introduced. Based on the hardware redundancy, a fault tolerance strategy for hack-to-hack PIVM converter open circuit fault is presented in this paper. According to the symmetrical structure, using the switching device, the grid side converter and rotor side converter compensate each other's function well, and the fault tolerant feature of back-to-back PWM converter is realized. The simulation results verify the validity of the proposed method.
