STATCOM Design for Voltage Control using Synchronous Vector PI Controller

Abstract

The objective of this paper is to improve Voltage profile of the system by controlling reactive power using a synchronous vector PI controller. Voltage in a power system is mainly affected by reactive loads and faults. This paper proposes modeling of a STATCOM (STATic+ COMpensator) with a synchronous vector PI controller under a nonlinear load. The prototype has been programmed in MATLAB/SIMULINK environment which has been tested on a standard IEEE 14 bus system. It has been observed that after installing STATCOM the voltages of the buses are found to be within the acceptable limits.
