Modelling and Analysis of TCSC Controller For Enhancement of Transmission Network

The method of series compensation is used since long back for improvement of power transfer capability of transmission line with the development of power electronics devices and control engineering TCSC becomes a multitasking controller to improve overall characteristic of an electrical power network in normal as well as faulty condition. In this paper, TCSC controller has been modeled and its performance has been analyzed for various events such as fault on long transmission line, sub synchronous resonance. The behavior of TCSC is analyzed for open and close loop modes. The results are verified by different power system parameter values using software package PSCAD 4.2.
