Analysis of TCSC for Real and Reactive Power Control using MATLAB/SIMULATION

Authors(4) :-Mohammad Shoaib, Shruti Fundkar, Ashish Vaidhya, Aniket Ladekar

A Thyristor controlled series capacitor (TCSC) belongs to the flexible alternatingcurrent transmission systems (FACTS). It is a variable capacitive and inductive reactance device that can be used to provide series compensation in power transmission lines. One of the significant advantages that a TCSC has over other series compensation devices is that the TCSC's reactance is instantaneously variable. This means that the TCSC can be used not only to provide series compensation but can also be used to enhance the stability of the power system. In this paper, performance of TCSC is analyzed. Initially, Real and reactive power flow through the transmission line have been analyzed for fixed and then after the same parameters are evaluated by inserting controllable capacitor in the same transmission network. The considered topology of TCSC consists of back to back thyristors that controls the reactance of the TCSC. By changing the firing angle of these back to back thyristors it is possible to vary the reactance of the TCSC. As per the TCSC characteristics, in inductive region at the firing angle 0 ? ? ? ?Llim the power flow decreasing and in capacitive region at the firing angle ?Clim ? ? ? 90 hence the power flow increase. For the simulation 1-phase model degree of compensation and the ratio of XC/XL is so adjusted to increase power transfer capability. The simulation is carried out by using MATLAB /simulink.
