Abstract

TCSCs are used in power systems to improve the profile of Voltage, flexibility and overall power flow capacity of power systems. The basic concept of TCSC usages is that by changing transmission line's impedance, increasing the power transfer capability is reachable and also changing the voltage profile of the system and affecting the stability is possible as well. In this paper, a full study has been done on affects of using Thyristor Controlled Series Capacitors on Voltage profile, Stability and Distance protection of the Power System. Simulations have been done on IEEE Standard model to verity the results. Results show that TCSC will improve Voltage profile and stability on system, But will decrease the accuracy on Distance protection operation since it changes the level of impedance and hence effect on the distance protection relay operation. References suggest using FCL technique to reduce effects of TCSC on Distance Protection. So, first a study on TCSC effects is done. Then, Voltage collapse possibility on stability discussions of power system will be studied. TCSC Simulation Results over stability and Voltage profile show that voltage collapse could be delayed in case of using a TCSC on transmission line. Simulation results on 14 Bus Standard IEEE system verify proposed theory.
