The modular assembly-type fault-tolerant operation of the wind turbine

The present invention discloses a wind turbine a modular assembly-type fault-tolerant operation, comprising a wind turbine, wind turbine fault-tolerant, modular power converter, multi-sensor signal detector, and determining an electrical fault indicator device, most whole Winds excellent torque control outer loop, the inner Fault Tolerant controller, logical 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.
