This paper investigates the performance of the single TCSC and proposed split TCSC on transmission system where India’s first TCSC project is installed in Kanpur Ballabhgarh (KB) line to ensure the fine tuning of line reactance by proposed split TCSC in place of existing KB TCSC. A three phase KB transmission system is developed in MATLAB/Simulink (SimPowerSystems) for a) without any compensati...

Series compensation of transmission lines increase the risk Sub-Synchronous Resonance (SSR) problems. Use Thyristor Controlled Compensators (TCSC) in place Fixed Capacitors (FSC) has benefited terms damping SSR. SSR Damping with TCSC can be achieved supplementary controls or through its inherent capability. discrete time models for small signal stability analysis is well established. This paper...

This paper presents a study of the performance of numerical distance relay for a 400 kV electrical transmission line compensated by series Flexible AC Transmission System (FACTS) i.e. Thyristor Controlled Series Capacitor (TCSC) is connected in the middle of the transmission line and can be used in voltage mode control or reactive power injection mode, and damping of power system oscillations i...

Flexible AC Transmission Systems (FACTS) controllers with its ability to directly control the power flow can offer great opportunities in modern power system, allowing better and safer operation of transmission network. In this paper, in order to find type, size and location of FACTS devices in a power system a Dedicated Improved Particle Swarm Optimization (DIPSO) algorithm is developed for de...

The problem regarding the optimal placement and sizing of different FACTS (flexible alternating current transmission systems) in electrical distribution networks is addressed this research by applying a master–slave optimization approach. analyzed correspond to unified power flow controller (UPFC), thyristor-controlled shunt compensator (TCSC, also known as thyristor switched capacitor, or TSC)...

For the improvement of transient stability the general methods adopted are fast acting exciters, circuit breakers and reduction in system transfer reactance. The modern trend is to employ FACTS devices in the existing system for effective utilization of existing transmission resources. These FACTS devices contribute to power flow improvement besides they extend their services in transient stabi...

Inter-area oscillation is a serious problem that threatens power system. Appropriate damping control of the inter-area would ensure grid stability and maintain tie-line transfer capability. In this paper, novel reinforcement learning (RL) based (POD) controller proposed uses Thyristor Controlled Series Compensators (TCSC) to damp oscillations. By leveraging unbiased gradient direction estimatio...

This paper presents an approach to find the optimal location of thyristor-controlled series compensators (TCSC) in a power system to improve the loadability of its lines and minimize its total loss. Also the proposed approach aims to find the optimal number of devices and their optimal ratings by using genetic algorithm (GA) with taking into consideration the thermal and voltage limits.
