    • 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.
    • 提供了风力发电机组故障处理方法和风力发电机组故障处理系统。 该方法包括:接收由检测元件发送的用于检测风力涡轮发电机系统的一部分的运行状态的检测信号,并将与风力涡轮发电机系统的该部分相对应的故障位设置为故障状态或非故障状态 - 根据检测信号的故障状态; 检测对应于风力发电机系统部分的故障位是否处于故障状态; 获取与故障状态的故障位对应的故障控制字; 并根据故障控制字确定与故障状态的故障位相对应的部分是否具有非停止故障,如果是,则对故障状态的故障位进行故障复位处理。
