高速铁路接触网系统风险评估与维修计划优化
Research on optimization of maintenance plan for high-speed railway catenary system based on risk assessment
摘要
Abstract
Because of the lack of comprehensive consideration of power supply equipment condition and fault loss in the catenary system maintenance management, a quantitative risk assessment model is proposed by using the fault Petri nets method and the loss level classing for counting failure rate. Taking the minimum maintenance cost as the optimization objective and the restrictions of risk cost and limited repair resources as the constraints, an optimization model for the risk-based high-speed railway catenary system maintenance program is built. To solve the optimization problem, a genetic particle swarm optimization algorithm with good convergence is designed. Simulation results show both reliability and fault risk of the high-speed railway catenary system can be controlled and the model can be used in actual operation.关键词
