Performance analysis of three leg DSTATCOM under distributed generation and fault scenario

Abstract

In modern power distribution system, use of nonlinear loads has increased drastically. Due to these nonlinear loads, power quality of the system is decreasing. Hence there is necessity of improving power quality of the system. Distribution Static Compensator (DSTATCOM) is a shunt connected custom power device, used in distribution system for performance improvement. DSTATCOM will maintain constant voltage at load terminals and maintains the shape of current and voltage by reducing the distortions. This paper presents a case study on investigation of performance of DSTATCOM at different operating scenarios. IEEE 13 bus industrial system is used to study the performance of three leg DSTATCOM. Voltage control mode with PI control is used to control RMS voltage at point of common coupling (PCC). � 2017 IEEE.
