基于广义无功功率理论的静止有源补偿

A Method of Static Active Compensation Based on Generalized Reactive Power Theory

在广义无功功率理论的基础上，采用正文变换，推导出综合电流表达式，提出静止有源补偿的构成和工作原理．采用最优脉宽调制技术（ＰＷＭ），实时、连续、动态补偿负载基波无功，抑制高次谐波，实现三相系统对称运行．仿真试验结果表明，理论分析和补偿方案是正确和有效的．

Based on generalized reactive power theory and the orthogonal transfor-mation,the expressions of comprehensive current are derived,and the constitution andoperation principle of the static active compensation are put forward.Using PWM technique,we can compensate fundamental wave reactive power of electric Ioad,restrainhigher harmonics,and realize the balance of three-phase systems timely,continuallyand dynamically. Simultation tests proved that theory analysis and compensation planare correct and effective.
