Abstract

Due to adaptation of new lifestyles, energy demand in the power sector rapidly increased day-by-day. To overcome this energy gap Flexible Alternating Current Transmission System (FACTS) controllers are the most reliable option irrespective to upgradation of power networks. Static Synchronous Series Compensator (SSSC) is one of a series family, second generation FACTS controller used in power networks to enhance power transfer capacity. In this paper, a new SSSC based indirect controller is proposed for a 500kV grid station. In SSSC, multilevel, 48pulse, Neutral Point Clamped (NPC) based Voltage Source Converter (VSC) is implemented that injects a controllable compensating voltage in series with transmission line. Almost 20% enhanced power flow can be achieved by using proposed cost-effective SSSC controller. The aim of this paper is to find drawbacks associated with previously designed controller and design a new controller for power flow improvement. Also compare their results for power flow in 500kV grid station using MATLAB/Simulink 2017 (a).
