摘要
An equal risk maintenance decision model based on minimum cumulative risk is proposed from the perspective of risk balancing of power grid. The scheduled load loss caused by power grid maintenance and unscheduled load loss caused by faults are comprehensively taken as the risk measure criterion of power grid, and an equal risk maintenance model is built with the objective of nearly equal risk during each period of power grid maintenance period. The calculation methods of fault probability of power grid and load loss are proposed, the contribution of each equipment to be examined to power grid risk under current operation mode is determined by the risk tracing method, and thus the decision sequence of equipments to be examined is determined by large to small order. The heuristic method based on minimum cumulative risk is adopted to solve the model for determining the maintenance interval of each equipment. Case shows that the proposed model can realize the objective of risk balancing and obtain small total risk during the maintenance period. © 2017, Electric Power Automation Equipment Press.
