摘要：

针对兆瓦级永磁同步发电机组并网的控制要求,基于三相电压型脉宽调制（PWM）整流器的数学模型,重点研究了直接电流控制双闭环级联结构的三相电压型PWM整流器和基于SVPWM的三相电压型PWM整流器的控制系统设计,提出基于双电压型PWM整流器（VSR）的风力发电机组的并网控制策略,并建立该控制策略的等效电路模型.通过对该并网控制策略等效电路模型的仿真分析,验证了PWM整流器的升压整流特性；同时,该等效电路输出的三相交流相电流总谐波畸变率仅为1.64%,电流波形正弦度良好.仿真结果验证了该并网控制策略的可行性．
Abstract:

For grid control of permanent magneticm synchronous generator, according to the mathematcalmodel of three-phase voltage source rectifier, this work emphatically studied the controller design of three-phase voltage source rectifier(VSR), which has double closed-loop and cascade structure based on the direct current control, and voltage source rectifier based on space vector pulse width modulation. The grid control strategy based on double voltage source rectifier for wind turbine generators was and proposed the corresponding equivalent circuit model was established. The simulation  to this grid control strategy's equivalent circuit proved the rising voltage speciality of pulse width modulation (PWM). The  current's total harmonic distortion of the grid side output's three-phase AC interphase was only 1.64%, and its waveform was batter. The new control strategy was proved feasible by Simulink simulation．
