Effects of Including SVC and TCSC in an Existing Power System Under Normal Operating Condition A Case Study
TLDR
A Newton-Raphson method-based load-flow program has been developed using existing standard software packages in which models of SVC as well as TCSC have been incorporated and the system performance under no-compensation, after SVC connection and after TCSC connection have been compared.Abstract:
This paper presents a case study on the effects of inclusion of Static VAR Compensator (SVC) and Thyristor Controlled Series Compensator (TCSC) on the impedances seen by different relays, present in a power system, under a variety of loading conditions. Newton-Raphson method-based load-flow program has been developed using existing standard software packages in which models of SVC as well as TCSC have been incorporated. A 5-bus and 7-line system ([1], [2]) has been examined with the developed program and the results have been presented through appropriate figures and tables. The system performance under no-compensation, after SVC connection and after TCSC connection have been compared.read more
