Design of a Demonstration Platform for Defect Assessment of Power Transmission and Distribution Equipment Based on Big Data

针对当前电网可靠性问题,结合输变电运行特点,在输变电设备缺陷分析平台需求基础上,提出一种基于Hadoop的输变电设备缺陷分析平台。首先分析该平台的需求,并给出系统整体架构;其次从数据存储和查询效率入手,采用Hadoop架构对数据进行存储,采用CMCH算法提高数据查询效率。再次构建设备缺陷评估模块,通过加权分值计算方式,实现设备缺陷等级的划分;最后通过搭建Hadoop平台对该方案进行验证,结果表明,该方案可有效提高数据查询能力,实现对输变电设备缺陷数据的处理。

Aiming at the reliability issue of the power grid operation at present and considering the characteristics of power transmission and transformation operation,a defect analysis plat⁃form for power transmission and transformation equipment based on Hadoop is proposed on the basis of analyzing the requirement of the defect analysis platform.Firstly,the requirements of the platform are analyzed,and the overall architecture of the system is given.Secondly,starting from data storage and query efficien⁃cy,the Hadoop architecture is used to store data,and CMCH al⁃gorithm is used to improve data query efficiency.At the same time,the equipment defect evaluation module is constructed,and the classification of equipment defect level is realized by cal⁃culating the weighted score.Finally,a Hadloop platform is build to verify the proposed scheme.The results show that the scheme can effectively improve the ability of data query and realize the processing of defective data of power transmission and transfor⁃mation equipment.
