摘要
在对电力系统有源无功与谐波补偿的原理进行理论分析的基础上 ,运用有关分析结果主要讨论了一种电力有源滤波器主电路及变结构非线性控制系统的组成和工作原理 ,给出一种变结构非线性电流跟踪控制的思路 ,通过 PSPICE软件对单相和三相系统进行了仿真研究 ,仿真结果证实了该系统及控制方法的正确性与可行性。
According to the theory of power active VAR and harmonic compensation,the contr ol scheme and principles of a power active converter circuit and its variable st ructure nonlinear control system for an active VAR and harmonic compensator are discussed.On this basis,a nonlinear variable structure control method of curren t track is proposed.Some simulation for single-phase and three-phase system w as carried out with the Pspice program package.Validity of the system is confir med with the simulation results.
