Generally in power transmission system, the power transfer capacity of a given transmission line should be increased so as to consume most of the power generated at power stations and at the same time controlling of reactive power has to be employed in order to increase the power transfer capability of a given transmission line. This could be achieved by installing certain FACTS (Flexible AC Transmission System) devices like TCSC (Thyristor Controlled Series Capacitor), STATCOM (STATic synchronous COMpensator) in the transmission lines. Further, attention should be paid as installation of such devices could affect the operation of distance relays.
