摘　　要：简述了并联型电能质量控制器(SPQC)的基本原理,为使SPQC实时有效的工作,可采用空间电压矢量脉宽调制(SVPWM)控制方法。介绍了SVPWM的传统算法。引入了一种SVPWM的算法,用Matlab6.5/simulink下的电力系统模块集把新算法实现的SVPWM应用到逆变器中。在此基础上,对三相SPQC进行建模仿真,仿真结果验证了该算法的正确性和其在SPQC中应用的可行性。SPQC （Shunt power quality controllers） is a new kind of power electronic device for suppressing harmonic. In this paper, the basic principle of SPQC was introduced. For the sake of real-time and validity of SPQC, control method of SVPWM can be adopted. A novel algorithm for SVPWM was introduced. A three-phase SPQC applied the novel control method of SVPWM was simulated by using power systems block set in Matlab 6.5/ simulink. The simulation results proved the accuracy of the novel algorithm and verified the feasibility of it in SPQC.
