Abstract

The invention relates to a post-investment evaluation method for a distribution network district, and the method comprises the following steps: (1), taking a power supply station as a unit, and collecting customer appeal indexes and district distribution transformer operation state indexes in the same time period before and after the investment of the distribution network district in a jurisdiction region of the power supply station; (2) respectively utilizing an AHP analytic hierarchy process to obtain a post-investment evaluation value based on customer appeals and a post-investment evaluation value based on a transformer district distribution transformer operation state; and (3) performing weighted summation on the post-investment evaluation value based on the customer appeal and the post-investment evaluation value based on the district distribution transformer operation state to finally obtain a comprehensive post-investment evaluation value of the power supply station. The higherthe score is, the better the investment effect is. Based on customer appeal information and operation state data, a big data means is applied, and the transformer area investment effect is comprehensively evaluated in a multi-dimensional mode.

Description

technical field [0001] The invention belongs to the technical field of electric power big data application, and in particular relates to a post-investment evaluation method of a distribution network station area. Background technique [0002] The State Grid Corporation proposed to always adhere to the corporate purpose of "people's electrical industry for the people" and invest in Taiwan areas that are in urgent need of improvement. But what is the effect of the company's investment, whether it has met the needs of power customers for power supply quality, and whether the company's precious investment funds have produced corresponding values. The post-investment evaluation of the application of distribution network is the most important thing to support the precise investment and construction project of the power grid. Heavy. [0003] At present, the post-investment evaluation of the distribution network area mainly considers factors such as load rate, heavy overload, and l...
