specific Embodiment approach

[0029] Aiming at the operation and maintenance cost of power grid enterprises, the present invention constructs a distribution network power equipment cost accounting method based on the life cycle cost theory, so that the power grid enterprises can accurately and reasonably estimate the cost of distribution network power equipment, and facilitate the power grid enterprises to effectively formulate the most good investment strategy. The specific implementation method comprises the following steps:

[0030] (1) Composition and estimation of upfront costs. The initial cost of distribution network power equipment reflects the one-time cost invested by power grid enterprises in purchasing the distribution network power equipment, which can be divided into distribution network power equipment purchase fees, distribution network power equipment installation and commissioning fees, etc.

[0031] The initial cost of the distribution network power equipment is expressed as:

[0032] ...

Abstract

The invention discloses a method for calculating the cost of distribution network power equipment based on the life cycle cost theory. At present, the distribution network power equipment market is not perfect, so it is difficult to infer the cost of distribution network power equipment through reasonable market transactions. The present invention includes: 1) composition and estimation of early-stage costs, including distribution network power equipment purchase fees and distribution network power equipment installation and commissioning fees; 2) mid-term cost composition and estimation, mid-term costs include operating costs and maintenance costs 3) Composition and estimation of late cost: late cost refers to the disposal costs and environmental protection costs generated by the scrapping of distribution network power equipment after the end of its life cycle; 4) The composition and estimation of the total cost of distribution network power equipment The sum of the costs in the three phases of , mid-term and later stages is taken as the total cost of the life cycle of distribution network power equipment. The invention is convenient for the power grid enterprise to effectively manage and control the cost of distribution network power equipment, and formulate the best investment strategy.

Description

technical field [0001] The invention belongs to the technical field of power grid operation cost management, in particular to a cost accounting method for distribution network power equipment based on the life cycle cost theory. Background technique [0002] The investment in distribution network power equipment is an important part of the fixed asset investment of power grid enterprises. The success or failure of investment decisions in distribution network power equipment is related to the cost of power grid enterprises, the efficiency of capital use, and even the competitiveness and viability of power grid enterprises in the market. At present, the distribution network power equipment market is not perfect, so it is difficult to infer the cost of distribution network power equipment through reasonable market transactions. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a distribution network power equipment co...
