应用智能电网统一数据模型的大数据应用架构及其实践
A Big Data Application Structure Based on Smart Grid Data Model and Its Practice
摘要
Abstract
Data fusion and management is fundamental for smart grid big data application.This paper investigated domestic and foreign data fusion work and its insufficiency,and summarized theoretical foundations,design process and methodology of unified data model construction.A complete data warehouse solution including smart grid data model (SGDM) was presented,which can be applied in various power application fields.In practice part,with open-source distribution network data,weather data in San Francisco,USA,simulated customer load data,optimization of data warehouse,statistical analysis and visualization were researched.In practice,big data architecture of 5 levels (source layer,staging layer,unified layer,business layer and presentation layer) was built,achieving balance between low data redundancy and high query efficiency.By optimizing database structure,analysis efficiency was further enhanced.关键词
