摘　　要：针对小型孤立风力发电系统输出电压和频率易波动特点,采用空间矢量脉宽调制技术(Space Vector Pulse Width Modulation,简称SVPWM),设计了小功率变流器控制电路。在Matlab/Simulink环境下建立了适用于风力发电系统的整流器与逆变器的模型,并进行了仿真。仿真结果表明,基于SVPWM控制的变流器可以很好的平抑风电机组输出电压与频率波动,满足孤立风电系统的供电要求。Aimed at the fluctuate characteristics of isolated wind power system export voltage and frequency, apply the Space Vector Pulse Width Modulation technology, design the control system of small capacity converter. Build the rectifier and inverter model in Matlab/simulink environment and simulated. The results show that the converter base on the control of SVPWM can dampen the wind power system output voltage and frequency fluctuations, meet the power supply requirement of the isolated wind power system.
