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 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 proj...

Embodiment 1

[0073] like figure 1 As shown, the power grid project operation benefit evaluation method that meets the electricity demand proposed by the present invention includes the following contents:

[0074] 1. Collect the actual operating power data that needs to be evaluated.

[0075] 2. Evaluate the performance of the power grid engineering project that meets the electricity demand according to the collected power data. The project performance evaluation indicators include the proportion of the system for the number of new lines, the proportion of the system for the length of new lines, the proportion of the system for the capacity of new units, The bayonet current verification ratio and the average power supply radius difference, the specific evaluation process of each evaluation index on the project performance is as follows:

[0076] 1) The proportion of the system in the number of new lines

[0077] Calculate the ratio K of the number of new lines to the number of system line...

Abstract

The invention relates to an electricity demand-satisfied power grid project operation benefit evaluation method and system. The method comprises the following steps of: acquiring to-be-evaluated practical operation electricity data; evaluating the efficiency of an electricity demand-satisfied power grid project according to the acquired electricity data; evaluating an effect of the electricity demand-satisfied power grid project according to the acquired electricity data; and evaluating the safety of the electricity demand-satisfied power grid project according to the acquired electricity data. According to the method and system, the operation effects of electricity demand-satisfied power grid projects are comprehensively evaluated by comprehensively 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 a power grid project that meets the demand for electricity, 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 ...
