Abstract :
Developing a high performance control strategy for grid side PWM converter of DFIG wind power generation system is a significant point. In this paper, first, deriving and analyzing the mathematical model of grid side PWM converter, a vector control strategy is proposed. Second, the voltage vectors influence on the active power change and the reactive power change was analyzed, a direct power control based on a new switching table was proposed. At last, comparative experiments were tested for vector control and direct power control strategy. The feasibility and correctness, advantage and disadvantage of the control strategy are verified by experimental results.
