Embodiment 1

[0053] figure 1 The flow chart of the optimal evaluation method for the cost of electric equipment based on the whole life cycle cost provided by the embodiment of the present invention.

[0054] refer to figure 1 , the optimal evaluation method of power equipment cost based on the whole life cycle cost, including:

[0055] Step S101, acquiring historical data of grid equipment;

[0056] Step S102, calculating the life-cycle cost of grid equipment according to historical data;

[0057] Step S103, establishing an economic life model of power equipment according to the full life cycle cost of power grid equipment;

[0058] Step S104, calculate the total cost of the grid equipment at any calculation time according to the economic life model, and obtain the economic life and life cycle cost of the grid equipment.

[0059] Specifically, the power grid equipment includes switchgear, transformers, power transmission equipment and secondary side equipment, wherein the switchgear i...

Embodiment 2

[0098] refer to Figure 4 , the optimal evaluation system of power equipment cost based on the whole life cycle cost, including:

[0099] An acquisition unit 10, configured to acquire historical data of grid equipment;

[0100] The first calculation unit 20 is configured to calculate the full life cycle cost of the power grid equipment according to historical data;

[0101] A model building unit 30, configured to establish an economic life model of power equipment according to the full life cycle cost of power grid equipment;

[0102] The second calculation unit 40 is used to calculate the total cost of the grid equipment at any calculation time according to the economic life model, and obtain the economic life and the whole life cycle cost of the grid equipment.

[0103] The optimal evaluation system of power equipment cost based on the whole life cycle cost provided by the embodiment of the present invention has the same technical characteristics as the optimal evaluation ...

Embodiment 3

[0105] For further understanding, this embodiment provides a specific calculation example analysis reference.

[0106] In this embodiment, a certain type of circuit breaker in a 35kV substation of Bazhou Power Grid is used for the application analysis of the life cycle cost of electric equipment. In the case simulation analysis in this paper, part of the fault data comes from the test data of the manufacturer, and part of it comes from the fault statistics data in the actual production of the unit; the operation data and cost data all come from the statistical data in the actual production of the unit.

[0107] First, the instantaneous dynamic cost distribution type of the circuit breaker is solved by collecting the historical fault data of this type of circuit breaker, and then the LCC model of the circuit breaker can be solved.

[0108] By collecting historical data of circuit breakers produced by manufacturers, the statistical results shown in Table 2.3 can be obtained.

Abstract

The invention provides a power equipment cost optimal evaluation method and system based on full life cycle cost. The power equipment cost optimal evaluation method comprises the steps of obtaining historical data of power grid equipment; calculating the whole life cycle cost of the power grid equipment according to the historical data; establishing an economic life model of the power equipment according to the whole life cycle cost of the power grid equipment; and calculating the total cost of the power grid equipment at any calculation moment according to the economic life model, and obtaining the economic life and the full life cycle cost of the power grid equipment. The power equipment cost is effectively measured through the method based on the full-life-cycle cost, the scientific reference of physical asset replacement, maintenance and investment is provided for a power grid enterprise, and the power grid enterprise is helped to scientifically develop physical asset management.

Description

technical field [0001] The invention relates to the technical field of power systems, in particular to an optimal evaluation method and system for power equipment cost based on full life cycle costs. Background technique [0002] In recent years, with the rapid development of modern industry and the continuous improvement of residents' electricity consumption level, while the investment and construction scale of power equipment and technology is increasing, the cost of power investment and construction is also increasing year by year. How to effectively control the power Cost control will be directly related to the healthy development of the power industry. [0003] However, the existing technology still lacks a method that can effectively measure the life cycle cost of power grid equipment, thus affecting a series of processes such as power equipment maintenance, renewal, and investment based on cost calculation, and causing serious damage to the management of power grid ph...
