Problems solved by technology

[0003] Due to the different functions of power transmission and transformation projects in the power grid, their evaluation indicators and evaluation standards should be focused and different. Electricity demand projects have high requirements for load rate, and use unified indicators and standards to evaluate all projects, ignoring the functional attributes of projects, and cannot provide targeted suggestions for the follow-up construction of such projects. This evaluation method It cannot fully reflect whether the fundamental goal of project construction is realized; the other is to divide power grid engineering projects into public network projects, special power transmission and transformation projects, and networking projects, and divide their roles in the power grid from the spatial and physical aspects of the project

Embodiment 1

[0067] Such as figure 1 As shown, the electric railway power supply network engineering operation benefit evaluation method proposed by the present invention includes the following contents:

[0068] 1. Collect the actual operating power data that needs to be evaluated.

[0069] 2. Evaluate the performance of the electric railway power supply project according to the collected power data. The project performance evaluation indicators include the system proportion of the number of new lines, the system proportion of the length of new lines and the buckle current verification ratio. Each evaluation index has a significant impact on the project. The specific evaluation process of effectiveness is as follows:

[0070] 1) The proportion of the system in the number of new lines

[0071] Calculate the ratio K of the number of new lines to the number of system lines l1 , to evaluate the contribution effect of the number of new lines in this project to the system.

[0072] K l1 =C...

Embodiment 2

[0229] The present invention also provides an electric railway power supply network engineering operation benefit evaluation system, including the following content:

[0230] A data collection module for collecting actual operating power data that needs to be evaluated;

[0231] A project performance evaluation module for evaluating the performance of the electric railway power supply project based on the collected power data;

The method comprises: actual running power data needing evaluation are collected; according to the collected power data, the efficiency of an electric-railway power supply project is evaluated; on the basis of the collected power data, the electric-railway power supply engineering project effect is evaluated; on the basis of the collected power data, project safety of the electric-railway power supply engineering is evaluated; and a running effect meeting a power usage need is evaluated comprehensively by considering the project efficiency, project effect and project safety.

Description

technical field [0001] The invention relates to a method and system for evaluating the operation benefit of an electric railway power supply network project, and relates to the technical field of power grid transmission. Background technique [0002] At present, there are usually two types of methods for evaluating the operational benefits of power grid engineering projects. One is to use the same set of index systems to evaluate the operational benefits of power grid engineering projects of all functional types. [0003] Due to the different functions of power transmission and transformation projects in the power grid, their evaluation indicators and evaluation standards should be focused and different. Electricity demand projects have high requirements on load rate, and use unified indicators and standards to evaluate all projects, ignoring the functional attributes of projects, and cannot provide targeted suggestions for the follow-up construction of such projects. This e...
