摘要
分析了基于矢量控制技术的PWM整流器的控制理论,给出了矢量运算模型和矢量图,并比较了电压闭环、电流开环和电压、电流双闭环控制方式的优劣,最终选择了电压、电流双闭环的控制方案。经过仿真验证,证明理论分析是正确的。可以广泛的应用在高压直流输电、电力传动系统、电力系统补偿装置中,并已获得良好的效益。
This paper analyzes PWM rectifier control theory based on the technology of vector control, given the vector operation model and the vector graph, and compare the voltage loop, open loop current and voltage, current pros and cons of double closed loop control mode, finally, using the voltage and current double closed loop control mode. Simulation results show the theoretical analysis is correct. Can be widely used in HVDC transmission, power transmission, power system compensation device and has obtained good results.
