摘要：
To solve engineering application defects such as lack of assessment details and risk information in the risk index system, this paper presents a power grid operation risk assessment and rating system. Firstly, redefine the risk structure as a set of risk grade, risk kind, risk probability, risk severity, reason set and consequence set, while classifying risk categories as loss of load, overload, voltage deviation, grid splitting, blackout of plant/station, and blackout of important users. Secondly, design the rating method of risk probability grade, risk severity grade and risk grade. Finally, divide the system flow into five parts as information collection, risk identification, risk assessment, risk rating and risk warning, and illustrate the system application effects in Dispatch and Control Center of State Grid Anhui Electric Power Company. ©2015 State Grid Electric Power Research Institute Press
