【摘要】 介绍了混合型有源电力滤波器(HybridActivePowerFilter,简称HAPF)的工作特点。基于该混合型有源电力滤波技术,并针对大容量谐波与无功补偿,提出了采用HAPF和电容器组并联补偿的方法;分析了由二者构成系统运行时,改善谐波补偿效果的电流检测方法和补偿特性;实现了HAPF与电容器组并联挂网运行,使总谐波畸变率下降约50%,功率因数由0.65提高到0.9以上。更多还原

【Abstract】 This paper introduces the characteristics of a hybrid active power fil ter first.For harmonic suppression and reactive power compensation of high power nonlinear load,a method of parallel operation of hybrid filter and capacitor banks is proposed.The compensating characteristics and current detection methods to improve the performance of harmonic suppression are also analyzed.It was rea lized to run the hybrid active power filter with capacitor banks in parallel,wh ich makes the total harmonic distortion rate decreasing by about 50 precents and the power factor raiding from 0.65 to more than 0.9.更多还原
