Power Quality Improvement by D-STATCOM in Distribution under Various Fault Conditions

Abstract

We know during fault condition power quality problem occur in system so for improvement of power quality we use different type of FACT device , but generally we used D-STATCOM . in this paper addresses the modelling and analysis of custom power controllers, power electronic-based equipment aimed at enhancing the reliability and quality of power flows in low voltage distribution networks using DSTATCOM. A new PWM- based control scheme has been proposed that only requires voltage measurements the operation of the proposed control method is presented for D-STATCOM. Simulations and analysis are carried out in MATLAB/SIMULINK with this control method for two proposed systems.
