有源电力滤波器(APF)是补偿电力系统谐波的重要装置,其控制策略与谐波检测方法对其性能有很大影响。介绍了滞环电流控制、空间矢量控制等多种有源电力滤波器的控制策略;分析了基于频率运算的谐波检测及瞬时空间检测等各种检测方法,指出了各种技术的优缺点。展望了有源电力滤波器的发展方向,近期主要集中在对谐波理论、控制系统的简化和数字化及补偿装置的多功能化等方面的研究。
Active power filter (APF) is an important device for compensation of power system harmonic waves, its control strategy and test method have great impact on its performance. Introduction was made to hysteresis current control, space vector control etc many kinds of active power filter control strategies; analysis was made to harmonic wave test and instantaneous space test based on frequency calculations, pointed out advantages and disadvantages of each technique. Looking forward to the development direction of APF, in the recent period, it is centralized in studying harmonic wave theory, simplification and digitize of the control system, multi-functionalization of compensation devices etc aspects.
