Power grid equipment life cycle cost calculation method

Abstract

The invention discloses a power grid equipment life cycle cost calculation method, which comprises a step of building a power grid equipment life cycle constitution model and a step of forming a peak shaving gap cost analysis and calculation method, wherein peak shaving gap cost analysis and calculation method further comprises the steps of dividing the life cycle cost into one-time investment cost and operation and maintenance cost, determining operation and maintenance cost best-fit distribution by adopting a grey system theory analysis method so as to acquire an operation and maintenance cost distribution relation, synthesizing the two parts of cost by combining a time allocation based one-time investment cost calculation method and taking the lowest LCC (Life Cycle Cost) as a target so as to form the power equipment life cycle cost analysis and calculation method. The power grid equipment life cycle cost calculation method achieves the purposes of reducing resource consumption and realizing effective control for the cost.

Description

technical field [0001] The invention relates to the technical field of combining engineering economics and power grid equipment in a power system, in particular to a method for calculating the life cycle cost of power grid equipment. Background technique [0002] The improvement of power grid asset management level is an effective guarantee for the national strategic energy security and the smooth lifeline of the national economy. It is the basis for power grid enterprises to improve quality services and fulfill social responsibilities. It is an important means to increase the income of state-owned assets and realize the scientific development goals of enterprises. With the deepening of my country's electric power market reform, the competition among electric power enterprises is intensifying, and all enterprises will face huge competition and challenges. In the past, domestic power grid enterprises only paid attention to the performance of equipment assets while ignoring th...

Problems solved by technology

In the past, domestic power grid enterprises only paid attention to the performance of equipment assets while ignoring the value of assets, and the traditional concepts and practices that valued input and neglected output benefits can no longer meet the requirements of power grid development under the new situation. While ensuring equipment reliability, extend the service life of equipment and reduce the cost of the whole life cycle, realize "strong power grid and excellent assets", reduce costs and improve efficiency to win competition and challenges

[0003] However, the current equipment management model usually only considers the cost from the early stage of the project to the completion and handover of the project, that is, the initial investment cost, and does not fully consider the operation and maintenance costs after the power equipment is put into operation. Incrementally, the proportion will also become larger and larger
