摘要

为了实现以设备状态为基础、系统运行风险最低为目标的先进检修模式

根据我国输变电设备状态评估的打分制体系

建立了估计设备故障率的最小二乘数学模型; 分析了现有用灵敏度指标来评价设备重要度的方法

提出以设备当前状态给系统带来的风险增量作为重要度评价指标; 考虑系统负荷和设备状态的时序变化

建立了以系统电量不足期望最小为目标函数的输电设备检修计划模型.对RTS-79标准系统的计算分析表明

风险增量指标的评价结果比灵敏度指标合理

据此所制定的检修计划可使检修规划期内的系统风险最低.

Abstract

Aiming at the perfect maintenance with the lowest system risk based on equipment condition

the scoring system for transmission and substation equipment state evaluation is referenced to establish a least squares model for estimating the equipment failure rate. By analyzing the sensitivity index

the risk increment index is introduced for assessing equipment importance. Taking sequential changes of system operation state and equipment condition into account

a transmission equipment maintenance scheduling model is proposed

which minimizes the total risk in the planning period. The risk increment index and the maintenance scheduling are verified by analyzing the IEEE RTS-79 standard system.
