Description

technical field [0001] The invention relates to a method and system for evaluating the operation benefit of a power grid project for power transmission, 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 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 evaluation meth...

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. Different evaluation indicators are set 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. As a result, the evaluation results deviate from the main problems to be solved by the project construction. Provide reference for the operation and construction of this kind of project 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 for power transmission grid projects, proposing evaluation indicators, and clarifying evaluation criteria from the perspective of different project system functions.
