基于Web的电力系统数据模型转换

为提高不同厂商提供的电力系统规划软件包的使用效率,实现电力企业的电网模型数据共享,设计了基于Web的电力系统数据转换应用(WebCPS)。分析了WebCPS的技术途径,系统建立在客户端、Web服务器、数据库服务器3层结构上,其中数据库根据银河科技调度自动化系统YH-9000系列数据模型(YH-DM)构造,软件采用组件技术实现;分析了用户接口组件和数据转换组件的构成,当公共信息模型(CIM)的数据文件上载后,系统将调用网络拓扑处理(NTP)组件分析电网模型,创建拓扑岛,网络拓扑处理结果将映射到相应的计算模型;讨论了系统的性能,即系统响应时间和最大文件大小;指出可通过增加数据模型调整、数据模型归并等方式提升系统性能。

Web-based data model conversion for power system

To improve the application effectiveness of power system planning simulation software packages from different vendors and realize power grid model data sharing in electric power enterprises,an approach,WebCPS(Web-based data model Conversion for Power System),is designed to convert the data model among different systems.Its technical approach is discussed.It has three tiers:client,Web server and database server.The database is constructed on YH-DM data model and the software is implemented with component technology.The constitution of UI(User Interface) and data conversion components is analyzed.When the data file of CIM model is uploaded,the NTP(Network Topology Process) component is called to analyze the model,the topology islands are created and the result is mapped into the corresponding computing model.System performance,response time and maximum file size are discussed.The system performance could be improved through data model tuning and merging functions.
