摘　　要：有源电力滤波器APF(active power filter)是补偿电力系统谐波及无功功率的重要装置,其控制的实时性和准确性是实现有效补偿的一个关键,就目前所研究的几种有代表性的单相APF方法进行了一一分析,阐述了它们的原理,并指出了它们的缺点和优点。其中逆变器输出电压恒定控制,单周控制,基于有功能量平衡原理的并联型有源滤波器由于能够保持逆变器输出端电压恒定,并且电流畸变率(THDi)能保持在5%以下,因而具有广阔的发展前景,就最后一种方法在Matlab7.0中进行了仿真,仿真结果表明,此种方法实现的APF具有很好的谐波补偿效果。Active power filter（APF）is an important device to compensate harmonic and reactive current in power system and the key of the effective compensation lies in the real-time and accurate control. The paper analyzes some representative methods on single-phase APF, and introduces the principle, points out their demerits and merits. Around them constant control on inverter output voltage, one-cycle control, the active power filter based on the active power balance theory has a better development because they can hold the inverter output voltage a constant value and keep the THDi below 5%. The paper simulates the last method in the Matlab7.0, which the result shows is quite simple and performs good harmonics compensation.
