Effect of electronic load in increasing shunt capacitor bank current

Abstract

This paper studies effect of power electronic load and its current harmonics in increasing current of shunt capacitance in the distribution network. Analytical method is done to show the effect of power electronic load on the current harmonic In order to show the proposed method effectiveness, a simple power electronic load is used including a rectifier bridge, a smoothing capacitor filter and a resistance. It has been shown that by increasing power electronic load, the shunt capacitance current is increased where the rate of current variation is related to the structure of power electronic load. MATLAB and PSCAD software's are used to simulate the proposed distribution network.
