Power Quality Enhancement using Hybrid Filter in Interconnected Grid System

Kavitha.D ^[2] | K. Rajangam

Abstract: The power quality problems have been paid a great attention because of their economical impacts on both utilities and customers. The most common problem for power quality is current harmonics, voltage sag and swell. The main objective of this paper is the mitigation of current harmonics to the grid side from non linear load, ensuring power factor correction and the protection of point of common coupling from voltage distortions. A transformerless hybrid series active filter is considered as a combination of H-Bridge and passive filter. Hysteresis current controller is proposed which will reduce the current harmonics and is used due to simple, fast dynamic response and insensitive to load parameters.
