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 oper...
