摘要
配电网作为供电环节中的最后一环,其运行水平决定了供电服务质量,因此配电网运行评价是供电单位的重要工作.但配电网运行评价工作受到跨业务数据资源难以融合、评价指标选择难以反映实际配电网运行状况等条件限制,现有评价方法难以实施应用.针对这一问题,提出一种基于多源数据深度融合的配电网运行评价方法,首先对区域配电网进行网格化划分,然后基于地址分级匹配算法对跨业务的多源异构数据进行深度融合.在此基础上,提取并设计配电网运行评价指标体系,构建基于多层权重约束的配电网运行综合评价模型,求解配电网综合评价结果.最后研发配电网运行评价系统,支持配电网各业务系统的多源异构数据的统一接入,实现配电网评价功能的可视化、智能化应用.研究成果配电网运行评价系统已采用某省级电网公司数据中台的相关数据进行配电网运行状态评估试验验证,以实际运行数据验证了所述方法的准确性和适用性.
Abstract
As the last link in the power supply process,the distribution network determines the quality of power supply services by its operational level.Scientific evaluation of the distribution network's operational level is thus an important task for power supply companies.However,the existing evaluation methods are difficult to implement and apply due to the fact that the multi-source data are hard to be fused and the evaluation indicators are poor in reflecting the actual operation status of the distribution network.To address above-said problem,this paper proposes an evaluation method for distribution network operation based on multi-source data deep fusion.Firstly,the regional distribution network is divided into multiple grids,and then the address gradation based matching algorithm is used to fuse multi-source heterogeneous data.Based on the results,the distribution network operation evaluation index system is designed and a distribution network operation comprehensive evaluation model based on multi-layer weight constraints is constructed to obtain the distribution network comprehensive evaluation results.Finally,a distribution network operation evaluation system is developed to support the unified access of multi-source heterogeneous data from various business systems of the distribution network,achieving the visualization and intelligent application of distribution network evaluation functions.The proposed distribution network operation evaluation system is connected to the data center of a provincial power grid company for verification,and the accuracy and applicability of the proposed method have been verified with actual operation data.
