Improvement of Power System Transfer Capabilities Using Thyristor Controlled Series Capacitor Compensation (TCSC)

Abstract

Electric power system faces many issues that limits their capability to work with max. Power transfer one of these issues are the faults that can occur on the inter connected power system which make some disturbance on the power system stability and control. In order to increase the power system transfer capabilities, the Flexible Ac transmission, system (FACTS) can be a solution with its different categories. One of categories is called thyristors controlled series capacitor (TCSC) which is connected in series with the network and used to increase the power transfer capability by controlled the overall effective transmission line impedance. TCSC shows great ability to control the real and reactive power along with voltage magnitude. But there is a leak of in information about the operation of TCSC during faults conditions. In this thesis, the operation of TCSC during fault conditions is taken in consideration. To do that, two-test systems was modelled using two Matlab software and Neplan program, the simulation results shows a great effect of TCSC on the operation of test systems.
