Power Balance and Control of Transmission Lines Using Static Series Compensator

Abstract

Parallel of transmission line system can be utilised for flow the power from a generating units to the load center in a meshed lines of power system grid. Distribution line currents flow in these parallel transmission depends on impedance value of line. Lowest value of impedance will reach maximum rating of transmission earlier than other transmission that in parallel paths and, while other transmission paths are not reached to its maximum rating. In this paper, a modeling and of parallel transmission lines is presented also series compensator SC inserted for regulating the flow power. The adaptive fuzzy logic control scheme is proposed, Takagi-Sugeno TS type is trained off line in this controller. The simulation results of this study show the ability of SC to regulate the flow of power in the controlled transmission between 50 to 100 percent of rated power.
