Power grid evaluating indicator correlation analysis method, apparatus and computing apparatus

Abstract

The invention discloses a power grid evaluating indicator correlation analysis method. The power grid evaluating indicator correlation analysis method is executed in a computing apparatus. The power grid evaluating indicator correlation analysis method includes the following steps that: a first evaluation indicator data sequence is obtained, wherein the first evaluation indicator data sequence includes a plurality of groups of combined evaluation indicator data; whether inclusion relations in indicator connotation exist on the first evaluation indicator data sequence is judged; whether causal relations in index logical exists on a second evaluation indicator data sequence is judged; whether function relations in indicator number exist on a third evaluation indicator data sequence is judged; whether membership relations in indicator structure exist on a fourth evaluation indicator data sequence is judged; if membership relations in indicator structure exist on the fourth evaluation indicator data sequence, a predetermined processing method is adopted to process the fourth evaluation indicator data sequence, so that a fifth evaluation indicator data sequence can be obtained; and the fifth evaluation indicator data sequence is outputted. The invention also discloses a corresponding power grid evaluating indicator correlation analysis apparatus and a computing apparatus comprising the power grid evaluating indicator correlation analysis apparatus.

Description

technical field [0001] The invention relates to a correlation analysis method, equipment and calculation equipment of power grid evaluation indexes. Background technique [0002] With the rapid development of my country's electric power industry and power system, the scale of the power grid has continued to expand, forming a multi-level power grid. For example, the provincial power grid at the lower level of the national power grid undertakes the UHV power grid, connects many power generation companies, and directly provides power products and services to medium and low voltage distribution network users. It is very important to monitor the power supply quality of power grids at all levels (such as provincial power grids). In order to strengthen the supervision of power supply quality, since 2001, the EU Energy Regulatory Commission has implemented power supply quality benchmarking. The European power supply quality benchmarking system includes three dimensions, namely powe...

Problems solved by technology

[0004] The existing index system generally has poor index consistency, repeated evaluation and other synergy and correlation problems that have not been properly resolved

The research on the specific existence forms of evaluation index correlations is not clear enough, and most of them are researched from the perspective of index information overlap, ignoring other existence forms of index correlations, such as logical causality, structural subordination, and quantitative functional relationship on
