【Abstract】 The statistics and analysis of nationwide operation situation of protective relayings and automation devices configured in the 220kV and above power systems in 2003 are summarized. The development and occurred failures of primary components, the operation situation and statistic data of element protections (including generator protection, transformer protection, busbar protectin and reactor protection) and that of the main protections of transmission lines (including high frequency protection, distance protection, zero-sequence protection and auto-reclosing) are presented. The reasons causing the misoperation of the protections and the corresponding responsibility to be taken on are pointed out.更多还原
