Wind energy conversion system under a supervisor deterministic finite state machine

This paper presents a simulation of an onshore energy conversion system connected to the electric grid and under a strategy of a supervisor control based on deterministic version of a finite state machine. The simulation is planned to address an analysis on performance due to the action of the supervisor. The supervisor is included at the higher level, having the objective of analyzing the operational states according to the wind speed. The energy conversion system is equipped with a doubly-fed induction generator and a variable speed variable pitch wind turbine. The analysis is carried by computer simulations and the obtained results allow assessment to the performance of the system. A comparison of the wind energy conversion system performance with or without the supervisor is carried out in order to access the influence of the strategy on the performance.
