基于全寿命周期管理的电力设备状态检修成本研究

Study on Electrical Equipment Condition-based Maintenance Cost with Life Cycle Cost Theory

全寿命周期成本(LCC)管理是以设备、项目的长期经济效益为出发点,全面考虑设备或系统从规划设计直至报废的全过程,以使成本最小化。在综合分析LCC理论发展的基础上,结合状态检修策略,通过分析变压器、开关、高压电缆电网主设备运维检修阶段LCC模型构成及参数灵敏度分析,区分识别出运维阶段主要数据,为电力系统全寿命周期管理系统构建提供参考。

Life Cycle Cost（LLC） management takes long-term economic benefits as starting point, and the whole process from design to retirement is fully considered in order to minimize costs. The development of LCC theory is analyzed firstly in this paper. Then, combined with condition-based maintenance strategy, the LCC model and sensitivity analysis of the key equipment such as transformer, switch, high voltage cable are studied. Finally, the key data in the operation and maintenance process is identified to give reference to power system life-cycle management system building.
