    摘要: A wind turbine generator system fault processing method and a wind turbine generator system fault processing system are provided. The method comprises: receiving a detection signal sent by a detection element for detecting a running state of a part of a wind turbine generator system, and setting a fault bit corresponding to the part of the wind turbine generator system in a fault state or a non-fault state according to the detection signal; detecting whether the fault bit corresponding to the part of the wind turbine generator system is in the fault state; acquiring a fault control word corresponding to a fault bit of the fault state; and determining whether a part corresponding to the fault bit of the fault state has non-halting fault according to the fault control word, and if so, performing fault reset processing on the fault bit of the fault state.
