Network side PWM converter voltage regulator control method

Wind energy as a clean and renewable energy has got the rapid development and it is one of the most important energy. In this paper, proposed the fuzzy control methods. That is through the fuzzy control method research, combined with direct-drive wind power system and the inverters characteristics in wind power system and using fuzzy control strategy to improve the system adaptability and fast in the network side of the system. This paper firstly introduced general fuzzy control method, secondly using fuzzy PI regulation to control voltage regulator loop and analysis the principle catachrestic of the fuzzy controller. Finally we simulate the practice. Simulation results show that the control system performance has been improved by using the method.
