摘要
Abstract
Detecting reactive and harmonic currents highly precise and real-time makes important influence on active power filter. In this paper, an improved method is proposed in order to detect the reactive and harmonic currents in single-phase power systems. It can detect the grid voltage phase angle based on the orthogonal characteristics without using the phase lock loop ( PLL ) and complex hardware circuit . The improved method can not only decrease the calculation capacity, but also detect the sum harmonic currents or the specific harmonic currents according to different requirements. It can be directly used in three-phase three-wire or three-phase four-wire systems to detect the reactive and harmonic current.关键词
