Embodiment Construction

[0056] The present invention will be described in further detail below in conjunction with the description of the drawings and specific embodiments.

[0057] see figure 1 , an equipment cost verification method based on LCC model, the method includes the following steps:

[0058] S1. Obtain N source cost data sets of N substation equipment in the same full life cycle, each source cost data set includes initial investment data, operation and maintenance cost data, maintenance cost data and fault cost data for the substation equipment , N≥2;

[0059] If there are two substations, the two devices can be divided into one indoor substation and one outdoor substation; if there are four substations, the four substations can be divided into two indoor substations and one outdoor substation. Two substations located outdoors;

[0060] The initial investment data and failure cost data of the substation equipment are transferred from the ERP system to the designated folder, and the ope...

Abstract

The invention discloses an equipment cost verification method based on an LCC model, and the method comprises the following steps: obtaining a single-source cost data set of power transformation equipment in the same whole life cycle, and carrying out the time sequence subentry calculation of the single-source cost data set through a preset equal-year cost calculation model, and obtaining a single equal-year cost set of the power transformation equipment in the whole life cycle; then, through a preset life cycle LCC model, respectively carrying out time sequence summarization on the equal-year cost sets to obtain a total cost sequence of the power transformation equipment in the life cycle; dividing the total cost sequences into first total cost sequences and second total cost sequences; and then performing advantage and disadvantage test on the second total cost sequences according to the first total cost sequences. According to the design, advantages and disadvantages of the whole life cycle cost of the power transformation equipment can be verified, simplicity, reliability and applicability are achieved, and a decision basis is provided for deployment of the power transformation equipment in the future.

Description

technical field [0001] The present invention relates to the technical field of power equipment, and in particular, to a method and device for verifying equipment cost based on an LCC model. Background technique [0002] The whole life cycle usually refers to the entire life stage of a project or product from design to scrapping. The life cycle cost usually refers to the total cost of the project or product in the whole life cycle. The LCC model usually refers to the Mathematical model for estimating life cycle cost. [0003] For the field of power equipment, the cost management method generally calculates the life cycle cost of power equipment by constructing and using the corresponding LCC model, which can not only improve the cost control efficiency of power equipment, but also provide certain decision support for the overall planning and lean management of power equipment. . Some power equipment is different in terms of equipment type, geographical environment, deployme...
