风力发电系统工作状态复杂多变，存在很多非线性的因素，常规模型难以展现其运行过程的变化。为了研究风力发电系统的状态转移，提高风电机组状态监控可靠性，运用事件驱动控制理论中的有限状态机建模方法，对机组工作状况与运行规则进行分析，把系统潜在的工作状态、风机运行参数以及状态转移条件等元素搭建成一个由外部条件触发事件，事件驱动状态转移的有限状态机模型。运用Matlab中的Stateflow模块进行仿真，仿真结果表明，此模型可以准确反映风力发电系统的运行状况，状态转移情况直观清晰，在风电机组的状态监控可以良好应用。

The wind power generation system is complex and variable, and many nonlinear factors exist under working condition. Due to the reason mentioned above, it is difficult for the conventional model to demonstrate the change of its operation process. To study the state transition process of wind turbine generator system and improve the reliability of wind turbine state monitoring system, with the method of finite state machine model, which is based on the event - driven control theory, the working cortditions and operation rules of the unit are analyzed. Meanwhile, by combining the elements of work...
