Modeling and Analysis of SVC, TCSC, TCPAR in Power Flow Studies

The paper mainly deals about the application of flexible AC transmission system (FACTS) to increase the power transfer capabilities for new operating scenarios in the bulk power systems. With the effect of FACTS technology improves transmission capabilities to reduce the system losses, and also improves the loadability of the power system. FACTs technology allows a better utilization existing transmission and generation reserve margins in the deregulated electricity market for various stability margins. In this paper discusses about the study state models of SVC (Static VAR Compensator), TCSC(Thyristor Controlled Series Compensator) and TCPAR (Thyristor Controlled phase angle regulator) is investigated for load flow environment to enhance the power transfer limits. A proposed algorithm has been tested on IEEE – 5 bus and 30 bus system in a specified line under voltage stability limits and results are tabulated. The proposed technique is simple and able technique to improve the system operation under study state condition.
