Power Transfer Capacity Achievement using Thyristor Controlled Series Capacitor

Abstract

Power system is the assembly of electrical networks, generating stations and different load centers. Load demand on the power system varies with respect to time parameter. Therefore more and more power requirements occur due to the power consumption. This can be achieved either by increasing the power carrying capability or by the re-evaluation of the electrical networks. It is observed that re-evaluation of the power system network is costlier than that of increasing the power transfer capability. In this research work a review of the salient features of power flow with thyristor controlled series capacitors are elegantly discussed. PSCAD-4.0 / MATLAB Program are used to observe how active and reactive power flow varied with different variable parameters and set of data. For each set of data, output result is obtained. Load flow solution of a 6-bus network by using Newton-Raphson method for control of power flow with TCSC (thyristor controlled series capacitor), in which the original 6-bus network is modified to 7-bus network to accommodate one TCSC / two TCSC. The load flow solution is found for the modified 6-bus / 7-bus network. The result of load flow solution shows that active power flow is controlled by TCSC. The salient feature of the research work is the fact that MATLAB and PSCAD-4.0 has been thoroughly used to investigate the different aspects of power flow control.
