Performance improvement of IEEE-30 bus system using UPFC and TCSC on PSAT

摘要

Due to rapid growth in industrialization and urbanization more capable transmission and distribution system is required to overcome the growing demand for electricity. So to meet up the demand of increasing power recent new technology, i.e., Flexible AC Transmission System devices (FACTS), has been developed in recent decades. The goal of the paper is to improve the voltage of a test system and compare the performance of two FACTS devices UPFC and TCSC. In this paper, we have used an IEEE- 30 bus as a test system and modeled it using PSAT software. First, we find the critical bus having a low voltage profile and then by trial and error method we searched for more efficient FACTS device at the appropriate location for maximum voltage enhancement of that critical bus.
