It is possible to increase line transmission capacities and to control these systems by providing reactive power compensation. In the recent years, FACTS (Flexible Alternative Current Transmission System) devices have been used as reactive power compensation elements. The study utilized rapid responding TCSC (Thyristor Controlled Series Capacitor) and SSSC (Static Synchronous Series Compensator) FACTS devices that are formed by power electronics elements. The effects of these devices on voltage stability, on the powers carried on the lines and the losses that occur on the lines were investigated with the simulation and its results. © 2011 Chamber of Turkish Electric.eninfo:eu-repo/semantics/closedAccessConference ObjectI127I131
