Abstract
The cost of power network operation and maintenance is affected by many factors, which will affect the cost. Among the many influencing factors, the geographical environment is one of the more important factors. The influence of geographical factors on cost is realized by geographical conditions including distance, topography, climate, etc. . When the distance is longer, the topography is more complex, and the climate change is more severe, for the operation and maintenance costs will have a higher increase in the effect.This paper analyzes the process that the internal and external composing mechanism of Power Grid Enterprise's operation cost is affected by geographical factors, and analyzes the influence way and result of geographical factors on power grid's operation cost.
Highlights
The study of power grid cost is always an important research hotspot
Operation and maintenance cost is the main cost of power grid operation, its cost management was extensive in the past, in 27 provincial companies management differences, did not form a unified and efficient company-level management system
For the operation and maintenance of substations and lines located in the mountains, hills and plains outside the city, geographical factors will be a major factor affecting the cost of operation and maintenance, so it should be explored from the inside and outside of the impact of geographical factors on the type of power grid cost
Summary
The study of power grid cost is always an important research hotspot. For the enterprise management, the cost determines the final business results of the important output indicators: The level of profits. Guided by China's domestic power reform policies, the power industry sector, especially grid enterprises, needs to deal with the regulatory authorities: The Energy Bureau's Electricity Price Regulation, in order to limit the monopoly profit of power grid, which is a natural monopoly, the supervision of transmission and distribution cost is an important part of the price supervision. The price of electricity directly depends on the transmission and distribution cost of power grid enterprises, especially the cost of operation and maintenance. The closed-loop Cost Management of power grid enterprises has not formed a perfect management system, and the current management level still can not meet the high requirements of accurate management and control costs. The objectivity of the evaluation method is often considered in the traditional evaluation, and the combination weight method is used to make the weight calculation process objective, delphi, AHP, FAHP, principal component method, entropy weight method, grey correlation method, sequence synthesis-g1 method, matter-element extension method and other methods are used to improve the objectivity of weight, but the consistency of different methods is ignored
