Yi Wang · East China Electric Power · 2009
It is of highly practical importance for modern power system to build smart grid diagnosis system in order to diagnose fault intelligently,improve fault identification validity,minimize blackout time and relieve dispatching people from high pressure.The upgrading and improved EMS and SCADA system make it possible to establish real time,automatic and intelligent fault diagnosis system.The system is based on the switch on-off information,SOE,relay protection information,PMU dynamic data,PMU recording data and the fault recording data of PMU.The author analyses the function of the system and presents the design of the data flow procedure,the interface and the displaying model for practical use.
