摘要
文中介绍了三相VSR的拓扑结构,给出了其在三相abc坐标系下和两相同步旋转dq坐标系下的的数学模型,并在此基础上引入了基于电流前馈解耦的双环控制系统。在分析了SVPWM的原理和实现方法后,给出了在SIMULINK下建立的模型并进行了相应的仿真研究,仿真结果表明,基于双环控制的系统具有动态响应快,抗扰性能好的特点。
This paper introduces the topology of the three - phase VSR, gives out the system model under the three - phase abc stat- ic coordinate axis and under the two - phase rotating coordinate dq axis. Then, the double loop control which based on the current feedforward decoupling method is introduced to control the three - phase VSR. On the analysis of the principle and realization meth-od of SVPWM, this paper builds the simulation of the system in the SIMULINK environment. The results suggest that the three - phase VSR based on the double loop control has fast dynamic response and good performance.
