摘要：
A fuzzy logic controller is designed to implement variable series capacitor compensation in the transmission network of interconnected power systems. This compensation scheme is one of the most widely accepted as a solution to limitations created by overstretched generation and transmission systems. This is one facet of flexible AC transmission systems (FACTS) employed to enhance the stability of the system. The effectiveness of the fuzzy logic controller to properly control such a variable series capacitor under different types of system disturbance is demonstrated through simulation studies on a single-machine infinite-bus system. The results of these simulation studies show that the controller can contribute tremendously to the enhancement of power system transient stability during such disturbances. Considerable increase in power throughput and significant improvement in the damping of the electromechanical oscillations are achieved by implementing this device in the transmission system.
