基于寿命周期成本管理的输变电设备状态检修策略研究

Study on policies of condition based maintenance of transmission and distribution equipments combined with life cycle cost management

针对目前电力系统中的输变电设备大多采用计划检修体制,存在着临时性维修频繁、维修不足或维修过剩、盲目维修等严重问题,引入输变电设备状态检修的方法,并结合寿命周期成本管理进行了理论推导。提出利用周期成本管理和设备风险总值计算出优先检修系数进行状态检修,在完成整个设备状态检修的风险决策的同时将输电设备的使用与维护成本最小化,具有工程实用性。

The current maintenance of electrical transmission and distribution equipments is time based maintenance.It always causes frequent temporary repair,inadequate or excess maintenance,blind repair and other serious problems.According to these,the paper introduces condition-based maintenance approach,and conducts theoretical derivation combined with life cycle cost management.Using the life cycle cost and equipment risk-value to calculate the priority maintenance factor and carry out the condition-based maintenance can not only accomplish the whole risk decision but also minimize the use and maintenance cost of transmission facilities.It is of the great practicality in the field of engineering.
