基于AHP-熵权法的配电网设备资产运检成本优化配置模型

电网公司已形成了输变配电设备资产运维检修标准成本体系,为适应成本监审、科学配置资源投入奠定了基础。由于配电网设备资产规模大,运维检修作业内容及频次繁琐,运维检修成本结构模糊,导致运维检修成本配置合理性仍存在不足,尚无法支撑成本精益管理。针对配电网运维检修成本配置问题,提出了基于层次分析法(analytic hierarchy process,AHP)-熵权法的配电网设备资产运维检修成本优化配置模型。基于配电网运维检修成本关键影响因素,建立了成本优化配置评价指标体系;兼顾成本投入合理性和有效性,采用熵权法对优化配置评价指标赋权重,构建区域配电网设备资产运维检修成本优化配置模型,合理有效分配各区域运维检修成本;以某省14家地市单位为例,验证了该模型的有效性及实用性。该模型能够较为合理地对配电网运维检修成本分配进行优化,并对比发现现有分配比例存在的问题,对配电网实际运维检修成本策略的制定有一定的参考借鉴作用。

AHP-Entropy Weight Method Based Optimal Allocation of Operation and Maintenance Cost of Distribution Network Equipment Assets

In recent years, power grid companies have formed a standard cost system for the operation and maintenance of transmission, transformation and distribution equipment assets, which lays the foundation for adapting to cost supervision and auditing and scientifically allocating resource input. However, the assets of distribution network equipment are large, the content and frequency of operation and maintenance work are cumbersome, and the cost structure of operation and maintenance is ambiguous. As a result, the rationality of operation and maintenance cost allocation is still insufficient, and it is still unable to support lean cost management. Aiming at the problem of distribution network operation and maintenance cost allocation, an optimal allocation model of operation and maintenance cost of distribution network equipment asset, which is based on AHP and entropy weight method, is proposed. Firstly, according to the key influencing factors of the distribution network operation and inspection cost, an evaluation index system for cost optimization configuration is established. Then, taking into account the rationality and effectiveness of the cost input, the entropy weight method is used to weight the optimal configuration evaluation index, and an optimal configuration model of operation and maintenance cost of equipment assets in the regional distribution network is constructed to reasonably and effectively allocate the regional operation and maintenance cost. Finally, taking 14 prefecture-level units in a province as an example, the validity and practicability of the model are verified. The model can reasonably optimize the distribution of operation and maintenance cost in the distribution network, and find the problems in the existing distribution ratio, which has a certain reference for the formulation of the actual operation and maintenance cost strategy of the distribution network.
