Performance Comparison between STATCOM and SVC to Enhance Power System Stability

Article Preview

Abstract:

This paper will discuss and demonstrate how FACTS controllers shunt Static Synchronous Compensator (STATCOM) and Static VAR Compensator (SVC) have successfully been applied to power system for effective regulating system voltage. One of the major reasons for installing a STATCOM or SVC is to improve dynamic voltage control and thus increase system load ability. In this paper a STATCOM and SVC are used to regulate voltage in a power system. When system voltage is low they generate reactive power (capacitive). When system voltage is high they absorb reactive power (inductive). In this paper comparison is also performed between SVC and STATCOM under fault condition and it is show that STATCOM have the ability to provide more capacitive power during a fault over SVC. All the simulations for the above work have been carried out using MATLAB/SIMULINK environment.
