摘　　要：本文基于电压型超导电磁储能系统(Superconducting Magnet Energy Storage,简称SMES)的基本结构和工作原理,结合脉冲宽度调制(Pulse Width Modulation,简称PWM)整流器的应用,建立了三相电压型PWM整流器控制的超导电磁储能系统的数学模型.设计了具有前馈解耦控制的PWM整流器双闭环控制系统,并运用Mat-lab/Simulink仿真分析软件对基于PWM整流器的超导电磁储能双闭环控制系统进行了仿真研究.仿真结果表明PWM整流器双闭环控制策略应用于SMES电压型SMES功率控制器比直接电流控制等传统的控制策略反应速度更快,向电网注入谐波电流更小,有利于提高了电网的稳定性.Based on the principle of Superconducting Magnet Energy Storage （SMES） and the usage of the rectifier with control mode of Pulse Width Modulation （PWM）, a kind of mathematical model, in which a SMES is controlled by a three-phase voltage source PWM rectifier, is established and a PWM rectifier double close＆loop control system with the control mode of fee＆forward decoupling is designed. Simulation results using Matlab/Simulink software reveal that such a system has some advantages such as quicker response and higher stability compared with conventional system.
