Simulation Aspects of Thyristor Controlled Series Compensator in Power System

The Thyristor controlled series compensator (TCSC) is one of the important members of FACTS family that is increasingly applied with long transmission lines by the utilities in modern power systems.It can have various roles in the operation and control of power systems, such as scheduling power flow; decreasing unsymmetrical components; reducing net loss; providing voltage support; limiting short-circuit currents; mitigating sub synchronous resonance; damping the power oscillation and enhancing transient stability control of power systems, systems and procedures are used to compensate dynamically the detrimental effect of nonlinear loads.The compensation process should be carried out without important alteration of the signal quality along with some benefits like reduction of losses in distribution lines, harmonic content minimization and power factor improvement.The dynamic behavior of industrial load requires the use of that compensator which can be adapted to the load changes.Thyristor Controlled Series Capacitor (TCSC) is an important FACTS device which has been used in power system transmission networks; these few aspects of the TCSC operation which we are simulating in ORCAD and MATLAB (i) To calculate the various resonance points in the impedance characteristics of the TCSC w.r.t.various firing angle.(ii) Contribution of the TCSC to power system operation and control system and study by implementing the TCSC in small power model of power system using ORCAD and MATLAB.
