统计综合法电力系统负荷建模平台的开发

Development of Load Modeling for Power System Based on Statistical Synthesis Method

针对统计综合法负荷建模工程实用化程度低的现状,开发一个统计综合法电力系统负荷建模平台。该平台由前台操作界面和后台服务器两大部分组成,对负荷特性数据进行分析、管理和应用。前台操作界面采用Visual C++6.0开发环境,应用模块整合技术,各功能模块既相互独立又相互关联。采用SQL Serv-er2000开发工具构建的数据库系统作为后台服务器。该平台操作简单,运行可靠,适用性强,扩展性好,能够方便建立各行业、各变电站的综合负荷模型,对统计综合法电力系统负荷建模具有实际工程意义,已在实际系统投入运行。

According to low practical use level of the statistical synthesis method, this article has developed an platform of load modeling for power system based on the statistical synthesis method. The platform （omposes by two major components of front interface and back-end server, which analyzes ,manages and applies the load characteristics datum. Front user interface uses Visual C＋＋6.0 development environment, and adopts modeling integrating technology, the functional modules are independent and interrelated. The database system built with SQL Server2000 acts as the back-end server. The platform has many advantages such as simple opera- tion, reliable operation, strong applicability and good scalability, which establishes various industries and substation model easily. It has practical emgineering significance in load modeling for power system based on the statistical synthesis method, and it has been put into operation in the actual system.
