电力有源补偿及滞环电流跟踪控制研究

本文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,运用其有关分析结果主要讨论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,给出了一种变结构滞环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。

Research on Power Active Compensation and Hysteresis Current Track Control

According to the theory of a power active VAR and harmonic compensation,the control scheme and principles of a power active converter circuit and its variable structure nonlinear control system for an active VAR and harmonic compensator are discussed.On this basis,a nonlinear variable structure control method of current track is proposed.Some simula- tions for single-phase and three-phase system are carried out with the Pspice program package.Validity of the system is confirmed with the simulating results.
