Development of FACTS operation technology to the KEPCO power network-installation and operation

KEPRI, the research institute of Korean Electric Power Corporation (KEPCO), has been investigating the feasibility of applying inverter type FACTS equipment into the local power system through a series of research projects. Based on the results, KEPCO has been working on a 80 MVA UPFC pilot plant (PP) project to be applied to the 154 kV system with a consortium formed with Hyosung Corporation, Siemens, and local research institutes since April, 2000. Through the knowledge and experience gained in application, installation, and operation of inverter type FACTS equipment on an actual 154 kV power system, KEPCO plans to derive the specifications and operation strategies needed to apply similar equipment to the 345 kV transmission system which is the backbone of the Korean power system.. This paper introduces the distinct features of the Korean power system, characteristics of the surrounding power system near the pilot plant installation site, equipment specifications, construction methods for application and operation of FACTS equipment to the local system, and future research plans.
