This paper describes the system aspects of 1100 kV AC transmission technologies with the UHV transmission project in Japan. For realization of technical and economical optimization throughout the design of the transmission line and the substation, solutions for network problems and insulation coordination specific to UHV AC transmission systems were studied in Japan. They include fast multiphase reclosing systems by HSGS (High Speed Grounding Switch) and overvoltage control by the application of surge arresters and circuit breakers with closing/opening resistors. These sophisticated technologies provide highly reliable and economical 1100 kV substations and transmission lines. Copyright © 2009 Institute of Electrical Engineers of Japan.
