【Abstract】 The scheme design and hardware structure of a new integrative fault location system for UHV Transmission Line are presented. Different fault location techniques based on the traveling wave and fundamental frequency components are integrated to provide a reliable and accurate fault location. In addition, the operating principles of specially designed traveling wave detector and high speed sampler based on GPS are also introduced. The new fault location system has been tested in the laboratory environments and satisfactory results are achieved.更多还原
