摘要
双馈风力发电机的并网是PWM整流器控制的主要目标,其并网控制性能的优劣直接影响到电网电压的稳定。网侧PWM整流器,主要研究PWM整流器的有功功率、无功功率解耦控制,并维持直流电压的恒定。本文主要针对电压型PWM整流器(VSR)进行研究,并对其dq模型进行改进,更有利于三相VSR控制系统设计,并在MATLAB/Simulink环境下进行了模型搭建和运行仿真。
The grid connection of the doubly fed induction generator （DFIG） is the main target of the PWM rectifier control. The control performance of the grid connected wind power will directly affect the stability of the grid voltage. The grid side PWM Rectifier mainly studies active and reactive power decoupling control and maintains a constant DC voltage. This paper mainly studies for voltage PWM Rectifier （VSR） and carried out improvements to its dq model, and then it＇ s more conducive to a three-phase VSR control system design, and the model is built and run in the MATLAB/Simulink environment.
