一种基于输配电定价成本监审建模的电网设备技改大修策略

A grid equipment technical overhaul strategy by modeling pricing cost supervision and audit of power transmission and distribution

该文研究了输配电定价改革背景下输配电价定价成本监审方法的数学模型及设备技改大修策略.通过对输配电定价成本监审办法的建模,分析了影响输配电定价的影响因子及其约束条件;指出有效资产原值与有效资产净值是影响电价的主要因素,且设备年龄结构是影响有效资产净值的主要因素;根据监审约束条件,进一步指出充分利用资产原值和运维费用增长空间是老旧设备技改大修处置中的努力方向.基于此,针对电力设备资产全寿命周期成本检修策略,改进了原有设备技改大修决策模型,对需要进行大修或技改的设备给出了更加明确的选择,有利于提升电网公司的经济效益.

In this paper,the mathematical model of pricing cost monitoring method for power transmission and distribution,along with overhaul strategy of equipment in the context of transmission and distribution pricing reform are investigated.By modeling pricing cost supervision and audit of power transmission and distribution,influence factors and their constraints of power transmission and distribution pricing are analyzed.It points out that the original value of effective assets and the net value of effective assets are the main factors influencing power prices,and the age structure of equipment is the main factors influencing the net value of effective assets.According to the supervision and auditing constraints, it is further pointed out that making full use of the original value of assets and the space for the increase of operation and maintenance costs is the direction of efforts in the disposal of old equipment technical reform and overhaul. Based on this, for the whole life cycle cost maintenance strategy of power equipment assets, the original equipment technical overhaul decision model is improved, which can give a clear choice whether equipment needs to be overhauled or technically modified, and help improve the economic efficiency of state grid companies.
