摘要
基于瞬时无功功率理论,提出了一种适用于三相三线制和三相四线制电力系统谐波、负序以及无功电流的复合补偿策略。数值仿真结果表明,该复合补偿策略的投入使用,可使电力系统综合补偿装置运行在有源电力滤波器和静止无功发生器功能相结合的复合工作模式,从而实现具有不对称非线性负载的电力系统的谐波抑制、无功补偿以及负载不平衡抑制等综合控制任务。
Based on the theory of instantaneous reactive power, this paper proposes a novel combined compensation strategy of harmonic, negative and reactive current for threephase three-wire and three-phase four-wire power system. The arithmetic simulation indicate that the strategy can make power system combined compensation devices working in the APF and SVG joint mode, so as to realize harmonic suppression, reactive power and load imbalance compensation simuhaneonsly under unbalanced non-linear load conditions.
