摘要：随着电力电子器件和控制技术的迅猛发展，三相PWM整流器已经广泛应用于风光储等各类新能源发电领域。本文基于三相电压型PWM整流器(VSR)拓扑和电网电压定向矢量控制策略，分析了三相VSR全工作过程中负载突变不同时刻的暂态工作特性，提出了一种交流侧电感和直流侧电容的工程设计方法；有针对性地阐述了考虑负载突变下三相VSR的软件和硬件设计原则。通过建立仿真模型，仿真分析结果验证了分析的正确性。

Abstract: With the rapid development of power electronic devices and control technology, three phase PWM rectifier has been used widely in windsolarstorage energy generation. The transient performance of threephase PWM rectifier (VSR) whole work process under load mutation was studied based on the topology of threephase voltage PWM rectifier and grid voltage oriented vector control strategy, and a method for AC side inductance and DC side capacitance was proposed. The design principle of threephase PWM rectifier considering load mutation was explained. The correctness of the analysis was verified by the simulation model.
Key words: PWM rectifier; whole work process; transient performance; design principle; result verification
