N-1 Reliability of 220kV Power Grid Under Maintenance
Currently,large-scale power outage may occur the fault of some out-of-operation device in grid may result in.Based on the full reference to the N-1 reliability of 220kV power grid under maintenance of other provinces and cities,this paper proposes the criteria for Shanghai Grid.The N-1 reliability criteria has been verified by analyzing the load loss of Shanghai 220kV power grid when its lines,channels or transformers are under maintenance.
