Evaluation system and method for intelligent substation

Abstract

An evaluation system for an intelligent substation comprises an evaluation service platform and at least one terminal center, wherein the evaluation service platform is connected with the terminal center. The terminal center conducts acquisition according to preset data or according to data issued by the evaluation service platform; a four-stage progressive structuralized evaluation index system construction method is adopted for an intelligent substation evaluation index system, wherein the four stages of the construction method refer to a technique layer, an index layer, a criterion layer and a target layer, and the technical advancement degree of the intelligent substation can be reflected. In order to reflect the overall technical development stage of different intelligent substations, the evaluation service platform adopts a grey clustering evaluation method for processing indexes to obtain gray clustering evaluation result values under different grey classes, and a technical development stage qualitative evaluation result and a technical advancement degree quantitative evaluation result of the substation to be evaluated can be reflected according to the gray clustering evaluation result values.

Description

technical field [0001] The invention relates to an evaluation system of an intelligent substation. The invention also relates to a method for evaluating an intelligent substation by using the method. Background technique [0002] Most of the existing substation evaluation index systems are proposed for traditional substations, and there are few literatures for the evaluation of smart substations. , He Benteng. Effectiveness evaluation model of intelligent substation automation system [J]. Electric Power System Automation, 2013, 37 (17): 87-94.) mentioned the effectiveness evaluation index of intelligent substation automation system, and initially established a comprehensive index system. The first-level indicators include 4 reliability, availability, real-time, and economical efficiency, 9 second-level indicators, and 19 third-level indicators. However, the design of this indicator system has the following defects: [0003] First of all, the establishment of the index sys...

AI Technical Summary

Problems solved by technology

[0003] First of all, the establishment of this index system is mainly based on the unified information model under IEC61850, which is difficult to reflect the improvement of substation operation status after the application of other technologies in smart substations, and has limitations in evaluating the overall situation of smart substation technologies

[0004] Secondly, the underlying indicators of this indicator system are based on the specific parameter indicators of each underlying device. Considering that the total amount of equipment in the smart substation is very large, the data collection work of this indicator system in practical applications is cumbersome and the workload is heavy, so it can be operated Poor sex

[0005] All in all, the existing smart substation evaluation system is only a work on paper. There is no implementable and operable smart substation evaluation system and evaluation method, and it is difficult to reflect the overall technological development. The evaluation results have limitations, which is not conducive to Development of Smart Substation
