| Abstract: | A serious fault was occurred in Shanghai Nanqiao Substation on Feb.19,2002 due to a monitoring system failure of P13 station,which caused a frequent close/open actions of circuit breakers and tripping of line and transformer protection relays,then finally the step out of Yanggao 220 kV system and the 500 kVsystem.With the fault recording document of the oscillograph and field test,an analysis was carried out on relay protection action during the accident process to provide important evident for failure analysis. |
