Abstract

A solution developed for power quality conditioning (PQC) applied in distributed generation system is presented. The method is exploiting the capabilities of the DC/AC converter of a system that has been developed to generate electric power by utilizing alternative, renewable and waste energies. The power quality conditioning is based on the application of space vector theory, using an algorithm easy to implement. The paper describes a control structure that is capable of both power factor correction and elimination of negative sequence components in the mains current. The theoretical analysis is confirmed by computer simulation results
