Information Fusion in the Application of Distribution Network Automation Management Evaluation

Abstract

In the evaluation of distribution network management level, analytic hierarchy process is generally adopted. By setting assessment criteria and scoring weights, this method can fully and accurately reflect the level of construction automation, development trends and weak links. It provides guidance for distribution automation construction and operation and maintenance. However, when applying this method to evaluate the distribution network, it is necessary to score the various influencing factors through experts. Because the expert scoring is subjective, the evaluation results are not the same according the different experts. In order to objectively evaluate the automation management level of distribution network, a method based on information fusion is proposed in this paper. According to the selected automation management evaluation indicators, an analysis model is established to obtain the distribution network evaluation results. Through the D-S evidence theory, the evaluation results of different experts are combined. And the subjective factors are combined to obtain a relatively objective evaluation result of the automation management level of the distribution network. Taking a certain urban area as an example, this paper evaluates the management level of distribution network by applying the proposed method. According results, it provides reference for grid economic evaluation, power grid planning and transformation work.
