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...

TCSC (Thyristor-Controlled Series Compensator) has been used in modern power systems to increase power transfer and system stability. Besides, due to its controllable feature, TCSC has been used to work as a solution to sub-synchronous resonance (SSR) problems. However, it is not clear so far whether TCSC’s inherent characteristic can avoid SSR and its effectiveness for SSR damping. In this pap...

This paper proposes an investment cost recovery based efficient and fast sequential optimization approach to optimal allocation of thyristor controlled series compensator (TCSC) in competitive power market. The optimization technique has been used with an objective to maximizing the social welfare and minimizing the device installation cost by suitable location and rating of TCSC in the system....

TCSC is equipment used to regulate and improve power flow in power system. The method used in this study was GSA. TCSC were the implemented on 500kV Java-Bali Power System. Loadflow results before optimization using Newton ...

Two-component signaling systems are widespread in bacteria, but also found in fungi. In this study, we have characterized TcsC, the only Group III two-component sensor kinase of Aspergillus fumigatus. TcsC is required for growth under hyperosmotic stress, but dispensable for normal growth, sporulation and conidial viability. A characteristic feature of the ΔtcsC mutant is its resistance to cert...

TCSC has been proposed to enhance the voltage stability by changing the reactive power distribution in the power system. Authors have discussed the effect of TCSC on steady state voltage stability and small-signal voltage stability. This paper discusses the TCSC’s enhancement on transient voltage stability. A TCSC model that is suitable for transient voltage stability analysis is proposed. This...

This paper describes a method to construct a linear model of a Thyristor-Controlled Series Capacitor (TCSC) by analyzing its time domain response when it is disturbed. All simulations are done in instantaneous value mode. With this technique, low-frequency dynamic behaviors of the TCSC are included in the linear model for both time domain simulations and linear analysis of the power system. How...

A basic conceptual study of TCSC device on Simulink is a teaching aid and helps in understanding the rudiments of the topic. This paper thus stems out from basics of TCSC device and analyzes the impedance characteristics and associated single & multi resonance conditions. The Impedance characteristics curve is drawn for different values of inductance in MATLAB using M-files. The study is also h...

This paper discusses control design issues for the existing thyristor controlled series compensation (TCSC) device at Slatt substation on the Slatt–Buckley 500-kV transmission line owned by BPA. The controls were developed at Washington State University (WSU) in a project funded by Bonneville Power Administration (BPA). The project has been carried out in close collaboration between the WSU tea...

This paper describes, in a tutorial manner, TCSC control aspects illustrated through simulation results on a small power system model. The analysis and design of the TCSC controls, to schedule line power and damp system oscillations, are based on modal analysis. and time and frequency response techniques. Transient stability results are included, to validate and refine the TCSC controller desig...
