基于有限状态机的变桨系统状态监测模型

摘要

Finite state machine in theory of discrete event system (DES)is used for modeling on wind power generation pitch system. According to operational process of the pitch system,the system is divided into eight operational states,transition of states is driven by nine events and events are triggered by variational parameters of the wind power generator. Stateflow module in Simulink is used for simulation and results indicate that this model is able to correctly reflect changes of working states of the pitch system in its operational process and state transition is intuitive and clear.%运用离散事件系统理论中的有限状态机对风力发电变桨系统建模，根据变桨系统的运行过程将其分为8个运行状态，状态的转移通过9个事件驱动，事件由变化的风机参数触发。运用 Simulink 中的 Stateflow 模块进行仿真，仿真结果表明，此模型可以准确反映变桨系统运行过程中工作状态的变化，状态转移直观、清晰。
