Easy maintenance inspection type fault-tolerant operation of wind turbines

The present invention discloses a convenient maintenance inspection operation of the fault-tolerant type of wind turbine, including wind turbines, wind turbine fault-tolerant, modular power converter, multi-sensor signal detector, an electrical fault determination apparatus and an indicator, the whole Winds optimal torque outer loop controller, Fault Tolerant inner loop controller, a logic switch the pulse width modulator drive. The present invention having fault-tolerant operation capability and low torque ripple of the wind turbine structure and driving control, it is possible under certain electrical fault appears unit case, and continued safe operation of power generation near rated capacity, and has a simple mechanical structure, strong electric reliability, a high degree of modularity and ease of assembly inspection and maintenance.
