Facts Placement for Maximum Power Transfer Capability And Stability in a Transmission Line

Maximum power transfer capability in the transmission line is the utmost important consideration in power systems. Facts devices are very effective and capable of increasing power transfer capability of a line, as thermal limit permits, while maintaining the same degree of stability. So, as to transfer maximum power to the consumer through a transmission line. Shunt FACTS devices are placed at the midpoint of the transmission line and degree of series compensation is provided to get the maximum possible benefit. It is observed that the optimal location of facts devices deviates from the centre of the line towards the generator side with the increase in the degree of series compensation.This paper presents a two stage approach a conventional method is used to determine the optimal location of shunt facts device in a series compensated line and then Fuzzy logic is used to determine the optimal placement. The proposed method is considered for 13.8KV Base, 6*350 MVA, 360 km long transmission line.
