基于边缘计算的台区状态综合评价方法

台区状态评价作为台区管理的重要环节,针对台区数据量大及缺乏规范管理等问题,文章提出了一种基于边缘计算的台区状态综合评价方法。首先将台区作为边缘计算节点,通过安装智能融合终端采集台区监测数据,并对数据就地化预处理；其次建立了一种台区特征指标体系；然后采用层次分析法和CRITIC法求出各指标的主客观权重；最后利用拉格朗日最优乘子法求得综合权重,给出台区的综合评分并判断台区的运行状态,同时将最终结果由智能融合终端上传至主站。通过对某地区的若干个台区进行实例分析,验证了该评价方法的可行性和有效性,具有一定的工程应用价值。

Comprehensive evaluation method of transformer area status based on edge computing

As an important part of transformer area management, the article proposes a comprehensive evaluation method of transformer area based on edge computing in order to solve the problems of large amount of data and lack of standardized management. First, use the transformer area as an edge computing node, collect the monitoring data of the transformer area by installing an intelligent fusion terminal, and pre-process the data on the spot; secondly, establish a transformer area characteristic index system; then use the analytic hierarchy process and the CRITIC method to find out The subjective and objective weight of each indicator; finally, the comprehensive weight is obtained by the Lagrangian optimal multiplier method, the comprehensive score of the transformer area is given, and the operation status of the transformer area is judged, and the final result is uploaded from the intelligent fusion terminal to the main station. Through the case analysis of several stations in a certain area, the feasibility and effectiveness of the evaluation method are verified, and it has certain engineering application value.
