In allusion to the increasing risk of cascading failures occurred in large-scale power grids and considering actual power grid operation conditions, operation characteristics of domestic large-scale power girds and existing risk factors of cascading failures, such as the risk of power system security and stability control devices, the risk of tie-line power flow control for UHV power grids, risk of power grid structure, risk of operating modes and risk of event of small probability and so on, are analyzed in depth. Based on analysis results and proceeding and from the viewpoint of operation and management of large-scale power grid, several generally suitable countermeasures are proposed according to different features of various types of risks, for instance building WAMS and risk early warning system, constructing power grid scheduling system for disaster prevention and speeding up the construction of integrated dispatching-control system, etc. Finally, the development of large-scale power girds in China is prospected.
