Technical Losses Reduction Using Static VAR Compensator

Abstract

One of serious problems in power systems that can threaten the concept of power system reliability and security is voltage instability and losses. Improving the systems reactive power handling capacity via Flexible AC Transmission system (Facts) devices is a remedy for prevention of voltage. The main objectives of this research are to investigate the methods of reduction the technical losses and corona losses in transmission line. And apply these methods in transmission line Marawi-Elmarkhiat as case study. Neplan Program was used to reduction these losses by static var compensator (SVC).And improved voltage. results show that the total losses about 22.017 MW, losses are reduced to 19.02 MW when installed static var compensator in main bus bar of kabashi substation.
