摘要:

旨在构建科学合理的电网设备更新决策方法,以实现电网企业的健康可持续经营。基于全寿命周期成本理论,引入威布尔模型计算成本,结合资金时间价值建立优化模型,求解最佳经济寿命与最低全寿命周期成本。从经济性、技术性和安全环保性3个方面构建综合效能评估体系,涵盖全寿命周期成本、可用性等6个指标,通过层次分析法和标准化处理完善指标量化。以A公司通信线路设备为例,更新设备数量较预期减少329 km,设备更新预算降低26.45%。结果表明所提模型有效降低了电网企业的运营成本,提升了设备综合性能,为设备更新决策提供了有力支持。

Abstract:

Aims to develop a scientific and rational decision-making method for power grid equipment renewal to achieve the healthy and sustainable operation of power grid enterprises.Basing on the theory of total life cycle cost (LCC),the Weibull model is introduced to calculate costs,and the time value of money is incorporatd to establish an optimization model.Thereby the optimal economic life and the minimum total life cycle cost are derived.A comprehensive performance evaluation system is constructed from the perspectives of economy,technology,and safety.It covers six indicators such as total life cycle cost and availability.The indicators are quantified through the Analytic Hierarchy Process (AHP) and normalization.Taking the communication line equipment of Company A as an example,the number of the renewal equipment is reduced by 329 km compared with the expected amount,and the equipment renewal budget is decreased by 26.45%.The results show that the proposed model effectively reduces the operating costs of power grid enterprises and enhances the comprehensive performance of the equipment,providing strong support for the equipment renewal decisions.

Key words: power equipment, total life cycle cost, comprehensive performance, equipment renewal decision
