摘要
针对直驱风力发电系统的特性,并与传统的交—直—交系统作比较,提出了采用脉宽调制(PWM)方法的一种新型整流器。本文对PWM整流器的原理进行了介绍,通过电压矢量跟踪控制,实现了机侧的整流,最后得出了仿真结果,验证了PWM整流器取代传统交-直-交系统的可行性。
In view of the characters of the direct-drive wind power system,and compared to the AC-DC-AC in the regulation, a novel controllable-PWM rectifier had been proposed. The principle of the PWM rectifier is introduced in this paper,then realizes commutate in side of the generator by controlling the AC voltage of the generator. Finally, the results of simulation are given. Feasibility of the PWM rectifier is validated in this paper.
