Description

Technical field [0001] The present invention relates to an assessment method and system of an electrical power supply grid engineering operation, involving power grid transmission technology. Background technique [0002] At present, the evaluation of the operational benefits of grid projects usually has two types of methods, and one is to use the same set of indicator systems for operational benefits for all function types of grid engineering projects. [0003] Due to the different functions that the transmission and electrical projects are borne, their evaluation indicators and evaluation criteria should have focus and different, such as electric power supply projects have higher safety requirements, and relatively low for load rates, satisfaction The use of electricity demand projects have higher requirements for load rate, and all projects are evaluated by unified indicators and standards, ignore the functional properties of the project, and can provide targeted recommendatio...

AI Technical Summary

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. 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.

[0004] To sum up, so far, there has been no research on building an evaluation system, proposing evaluation indicators, and clarifying evaluation criteria for meeting electricity demand from the perspective of different system functions of engineering projects.
