Problems solved by technology

[0004] But the disadvantage is that due to the different functions that each power transmission and transformation project can achieve, it plays a different role in the entire power grid, and thus has different impacts on the safety, stability and reliability of the entire power grid. The equipment in the power transformation project is different, so the probability of failure is also different. It can be seen that the accuracy of the above method to control and allocate the operation and maintenance costs of each power transmission and transformation project is low

Embodiment 1

[0032] see figure 1 , the embodiment of the present invention provides a method for controlling the operation and maintenance fee of a power transmission and transformation project. Generally, a power transmission and transformation project mainly includes two parts: a substation and a transmission line. Therefore, the operation and maintenance of a power transmission and transformation project in this embodiment Cost control methods include:

[0033] Step S1: Obtain the operation and maintenance data of the reference power transmission and transformation project in previous years, and obtain the operation and maintenance fee of the unit capacity substation and the operation and maintenance fee of the unit length transmission line according to the operation and maintenance data of the previous years;

[0034] Step S2: Obtain the main transformer capacity of the substation of the current power transmission and transformation project, and obtain the operation and maintenance fee...

Embodiment 2

[0089] see Figure 4 , the embodiment of the present invention provides a control system for the operation and maintenance fee of a power transmission and transformation project. The control system includes a data processing unit 100 , a fee calculation unit 200 and a fee data output unit 300 connected in sequence. Among them, the data processing unit 100 is used to obtain the operation and maintenance data of the reference power transmission and transformation project in previous years, and obtain the operation and maintenance fee of the unit capacity substation and the operation and maintenance fee of the unit length transmission line according to the operation and maintenance data of the previous years; the cost calculation unit 200 is used for Obtain the main transformer capacity of the substation of the current power transmission and transformation project, and obtain the operation and maintenance fee of the substation of the current power transmission and transformation p...

Abstract

The invention provides a method and system for controlling the operation and maintenance cost of a power transmission and transformation project, and relates to the technical effect of power transmission and transformation, so as to improve the control accuracy of the operation and maintenance cost of the power transmission and transformation project. The method comprises the steps: obtaining the historical operation and maintenance data of a reference power transmission and transformation project, and obtaining the operation and maintenance cost of a transformer substation with a unit capacity and the operation and maintenance cost of a power transmission line with a unit length; obtaining the main transformer capacity of a transformer substation of a current power transmission and transformation project, and obtaining the operation and maintenance cost of the transformer substation of the current power transmission and transformation project through combining with the result of the former step; obtaining the length of a power transmission line of the current power transmission and transformation project, and obtaining the operation and maintenance cost of the power transmission line of the current power transmission and transformation project through combining with the result of a first step; and obtaining the operation and maintenance cost of the current power transmission and transformation project. The method provided by the invention is used for controlling the distribution control of the operation and maintenance cost of the power transmission and transformation project.

Description

technical field [0001] The invention relates to the technical field of power transmission and transformation engineering, in particular to a method and system for controlling operation and maintenance fees of power transmission and transformation projects. Background technique [0002] The power grid is a network system that can realize functions such as power transmission and power distribution. The core project of power grid construction is the power transmission and transformation project, and the power transmission and transformation project mainly includes two parts: substations and transmission lines. [0003] In order to ensure the reliability and economy of power supply during the operation of the entire power grid, it is necessary to invest a certain amount of operation and maintenance fees in each power transmission and transformation project. Usually, the method of controlling and allocating the operation and maintenance fee of a certain power transmission and tra...
