Comparative Analysis of TCSC and STATCOM in Power System

摘要

The demand for electrical power has grown at faster rate due to increasing population. The recent progressions in power electronic area have presented Flexible AC Transmission Systems (FACTS) control equipment and these modules enhance the power transfer capability, improves stability, security of the power system. The principle operating modes and applications of FACTS equipment in power system such as Static Synchronous Compensator (STATCOM), Thyristor controlled series capacitor (TCSC) are discussed here. TCSC and STATCOM, in which one is series compensator and another is shunt compensator respectively, Main objectives in this work are to control the active and reactive power flow, voltage regulation in the network using above FACTS devices and Comparative study of TCSC and STATCOM using SIMULINK/MATLAB is carried out. A case study of IEEE standard five-bus system is modelled in the Mi-power, different cases have been worked out and comparative results are tabulated. Finally the best suited FACTS device is suggested for the application in transmission lines.
