摘要
随着智能电网和电力企业信息化水平的纵深发展,企业积累了海量结构多样、来源复杂、规模巨大的数据资源。为了有效提高海量异源异构数据的集成与共享,实现企业统一数据交换以及数据价值发现,文章以临沂供电公司现有的数据集成架构和数据管理现状为依据,搭建了基于Hadoop架构的企业数据共享平台整体架构。然后,在基于数据仓库的数据集成模式的基础上,进一步构建了基于Hadoop架构的电力企业数据共享模型。该模型主要包括HDFS元数据管理方案、黑板模型、"发布-订阅"的数据分发策略以及基于Hbase的数据共享运行模式。此模型对于海量数据共享与处理具有廉价扩展、高效容错、高可靠性等优势,从而逐渐消除信息壁垒,促进数据共享与业务融合,实现电力企业数据的集中管控、综合治理和高度共享,为电网企业的正常运营管理提供科学决策和参考依据。
With the deep development of the information level of smart grid and power enterprise, enterprises have accumulated huge amounts of data resources, which are massive, diverse, complex and huge. In order to improve the integration of massive heterogeneous and sharing of data, realize the enterprise unified data exchange and data value, according to the company＇s existing data integration architecture and data management as the basis, this paper built the overall structure of enterprise data sharing platform based on Hadoop architecture. Then, on the basis of data integration model based on data warehouse, the data sharing model of power enterprise based on Hadoop architecture was further constructed. This model mainly included HDFS metadata management scheme, blackboard model, publish and subscribe data distribution strategy, and Hbase based data sharing operation mode. The advantage of this model for massive data sharing and processing with low expansion, efficient fault tolerance and high reliability, which can eliminate the information barriers, promote data sharing and business integration, realize the centralized management of electric power enterprises, the comprehensive management and data sharing, provide scientific decision-making and reference for the normal operation of management for power grid enterprises.
