摘　　要：针对直驱型风力发电不控整流+Boost+PWM逆变器并网拓扑结构,利用Matlab/Simulink软件平台,搭建了整个并网系统的仿真模型,并对网侧PWM逆变器进行了控制策略的研究。仿真结果表明,这种控制策略能稳定直流电压,使风电机组能正确地并入电网,实现了有功、无功的解耦及单位功率因数控制。Aiming at the topology structure of un-controlled rectifier＋Boost＋PWM inverter in the direct drive wind power,a simulation model is build up based on the toolbox of Matlab/Simulink software,and a control strategy for PWM inverter is researched.The simulation results show that this control can stabilize the DC voltage,and make wind turbine be properly connected to the grid,achieve active,reactive decoupling and unity power factor control.
