Performance analysis of series hybrid active power filter

Abstract

In the area of active power filtering, the Series Hybrid Active Power Filter (SHAPF) has been taken into account increasingly. Existing methods used for controlling SHAPF are either based on detecting source current harmonics or load voltage harmonics. Generalised Instantaneous Power Theory (GIPT) gives simple and direct method of defining power quantities under sinusoidal and non-sinusoidal situations. In this paper the definition of GIPT is used to decompose voltage vector into different components, which represents different parts of the power quantity. The separated components of voltage vector are used to derive reference signal for the SHAPF. This paper presents a study on performance analysis of SHAPF where the method used for calculating reference is based on the GIPT. Steady state and transient performance of SHAPF used for compensating current type harmonic producing load and voltage type harmonics producing load are evaluated by the simulation study. © 2013 Springer Science+Business Media Dordrecht.
