Combination Of Shunt Connected Converters To Synchronize Voltage And Harmonic Current Suppression

Kbvsr. Subrahmanyam, M. Praveen Kumar


This project presents the growing installation of distributed generation (DG) units in low voltage distribution systems has popularized the concept of nonlinear load harmonic current compensation using multi-functional DG interfacing converters. It is analyzed in this paper that the compensation of local load harmonic current using a single DG interfacing converter may cause the amplification of supply voltage harmonics to sensitive loads, particularly when the main grid voltage is highly distorted. The second converter is used to mitigate the harmonic current produced by the interaction between the first interfacing converter and the local nonlinear load.
