Cross-provincial and cross-regional power transmission channel power grid project operation benefit evaluation method and system

Abstract

The present invention relates to a method and system for evaluating the operation benefits of a cross-provincial and cross-regional power transmission channel power grid project, including the following content: 1) collecting the actual operating power data of a certain cross-regional and inter-provincial power transmission channel project that needs to be evaluated; 2) according to the collected Evaluate the project effectiveness of the cross-regional and inter-provincial power transmission channel project based on the power data; 3) evaluate the project effect of the cross-regional and cross-provincial power transmission channel project according to the collected power data; 4) evaluate the project effect based on the collected power data Evaluate the project safety of cross-regional and cross-provincial power transmission channel projects; 5) comprehensively consider project efficiency, project effect and project safety, and comprehensively evaluate the operation effect of cross-provincial and cross-regional power transmission channel power grid projects. The invention can be widely used in the evaluation process of the operation benefit evaluation process of the cross-province and cross-region strengthening power transmission channel power grid project.

Description

technical field [0001] The invention relates to a method and system for evaluating the operation benefit of a power grid project of a cross-provincial and cross-regional power transmission channel, 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. Due to the different functions of power transmission and transformation projects in the power grid, their evaluation indicators and evaluation standards should be different. Projects that meet electricity demand 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 subsequent constructi...

AI Technical Summary

Problems solved by technology

Due to the different functions of power transmission and transformation projects in the power grid, their evaluation indicators and evaluation standards should be different. Projects that meet electricity demand 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 subsequent construction of such projects. The method 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 levels of the projects. , set different evaluation indicators for each project to evaluate project operation benefits. This type of evaluation method has a coarse granularity and does not fully consider the main role of the project in the power grid, which leads to the evaluation results deviating from the main problems to be solved by the project construction. It cannot provide reference for the operation and construction of such projects in the future

In addition, the indicators involved in the above two methods have no set evaluation standards, and the evaluation process is highly subjective.

To sum up, so far, there has been no research on building an evaluation system, proposing evaluation indicators, and clarifying evaluation criteria for cross-provincial and cross-regional power transmission channel power grid projects from the perspective of different engineering project system functions.
