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...

The process of selecting optimal settings for directional over-current relays (DOC relays) is a selection time dial setting (TDS) and IP (backup current), So that changes in the system electrical power distribution. In this work, breeder genetic algorithm (BGA) has been applied to DOC with multisystem D-FACTS devices. simulation consists two network operation scenarios, scenario without which c...

Power system engineers are currently facing challenges to increase the power transfer capabilities of existing transmission system. This is where the Flexible AC Transmission Systems (FACTS) technology comes into effect. With relatively low investment, compared to new transmission or generation facilities, the FACTS technology allows the industries to better utilize the existing transmission an...

This paper presents a framework to carry out an novel method based Optimal Power Flow (OPF) for transmission congestion management in deregulated power system using Thyristor Controlled Series Capacitor (TCSC) and Generation Rescheduling. In the deregulated environment, some generators may not be willing to participate in the congestion management process for their own economic interest or some...

Accumulated evidence suggests that in addition to hematopoietic stem cells (HSC), bone marrow (BM) also harbors endothelial stem cells (ESC), mesenchymal stem cells (MSC), multipotential adult progenitor cells (MAPC), pluripotent stem cells (PCS) as well as tissue committed stem cells (TCSC) recently identified by us. In this review we discuss the similarities and differences between these cell...

Instead of building new substations or transmission lines, proper installation of flexible AC transmission systems (FACTS) devices can make the transmission networks accommodate more power transfers with less expansion cost. In this paper, the problem to maximize power system loadability by optimally installing two types of FACTS devices, namely static var compensator (SVC) and thyristor contro...
