thyristor-controlled series compensator (tcsc) is one of the electric power lines series compensators. tcsc increases transmission system capacity and improves system dynamic and voltage stability. several controllers have been proposed, but most of them generally improve one of tcsc capabilities. in this paper a tcsc robust controller is designed based on nonlinear quantitative feedback theory...

In this paper, a novel approach to analyse, extract and validate the key characteristics of the fault transient phenomena on a thyristor controlled series capacitor (TCSC) compensated transmission line is introduced. This method relies on utilising discrete wavelet transform (DWT) to decompose the traditional busbar voltages and line currents obtained from a single terminal into a series of tim...

In this paper a novel method for finding the fault zone on a Thyristor Controlled Series Capacitor (TCSC) incorporated transmission line is presented. The method makes use of the Support Vector Machine (SVM), used in the classification mode to distinguish between the zones, before or after the TCSC. The use of Discrete Wavelet Transform is made to prepare the features which would be given as th...

This paper gives a brief review of fast and flexible control of power flow in transmission lines. Special emphasis is on SVC, TCSC and UPFC looking towards their benefits for improving the operation of an electrical power system. Performance comparison of these FACTS controllers has been discussed. In addition, some of the utility experience have been reviewed and summarized. Applications of FA...

Algorithm (GA) approach to tune the parameters of a Thyristor Controlled Series Compensator (TCSC), for power system stability improvement. Pareto method type of selection is used in the present multi-objective GA approach, which gives a set of solutions from which the best one can be chosen according to the requirements and needs. The design problem of TCSC controller is formulated as a parame...

This paper presents a methodology to assess the voltage stability status combined with optimal power flow technique using an instantaneous two-bus equivalent model of power system incorporating static var compensator (SVC) and thyristor controlled series compensator (TCSC) controllers. There by, a generalized global voltage stability indicator being developed has been applied to a robust practi...
