jee.11.1.13676 Modelling and Analysis of D-Facts Device: Enhanced Power Flow Controller Dheeraj Kumar Dhaked Mahendra Lalwani Journal on Electrical Engineering 2230–7176 11 1 41 49 https://doi.org/10.26634/jee.11.1.13676 D-FACTS, FACTS, Power Flow Control, TCSC Flexible AC Transmission System (FACTS) controllers control the power flowing through transmission lines to improve utilization of power system, transmission loop flow control, reliability and relieve congestion. High cost, reliability and land restriction issues have limited their use in the power system. The Distributed-FACTS (D-FACTS) controller is presented as a new approach to recognize economic power flow control through compound, small, fixed series impedance injections. A new device which is distributed version of Thyristor Controlled Series Capacitor (TCSC) controller, Enhanced Power Flow Controller (EPFC), connects directly to the existing high voltage or extra high voltage lines. It can be manufactured at a lower price than FACTS controllers from conventional low-grade components. This EPFC is distributed over whole transmission line as modules at every short span of length of transmission lines to attain the required power flow control functionality by changing the transmission line reactance dynamically or statically. It uses the concept of DFACTS to control the power flow. The results from an EPFC MATLAB/Simulink model are presented in this paper on a transmission system which is connected with EPFC controller modules.
