摘　　要：在总结已有的研究成果基础之上,将瞬时无功功率理论应用于提高功率因数和补偿三相不平衡的静止无功功率补偿装置控制之中,简化了瞬时无功功率算法,提出了更为有效的滤波器结构,推导出补偿电纳的表达公式,动态模拟试验和仿真试验证明了算法的有效性和可行性。Based on the research findings obtained before, instantaneous reactive power theory is applied in the control of static var compensator （SVC） to increase power factor of power supply system and compensate unbalanced three-phase current. Firstly, this paper analyzes mode of voltage and current phasor motion, thereby to propose the tactics of separating the key variable. And the mean value filter is put forward after comparing the impact of different filters. At last, to reduce calculation amout, a simple expression of compensation susceptance is deduced. And the dynamic simulation experimentation proves the availability and feasibility of the method.
