中文摘要：
为了补偿电力系统中的无功功率和谐波，给出了基于瞬时功率理论的ip-iq法检测无功功率；而对谐波的检测，采用基于单相电路的检测方法。并对2种方法进行理论研究和仿真分析。最后对目前常用的无功功率和谐波的静态和动态补偿装置进行了分析对比。
英文摘要：
To compensate reactive power and harmonic in electric power system, reactive power is detected via ip - iq method based on instantaneous power theory;and harmonic is detected via the method based on single- phase circuit analysis. Two methods are researched in theory and analyzed in simulation. Finally, the static and dynamic compensator for reactive power and harmonic are analyzed and compared. To compare advantages and disadvantages of compensator can give certain guidance for their design and selection in actual production.
