基于CIM标准和SVG的分散式图模合并

电力系统调度一般采用分级电网监控方式，各级调度系统的电网模型及采集信息相对独立，存在一定的信息孤岛问题。基于公用信息模型（CIM）标准和可缩放矢量图形（SVG）画面格式，提出了分散式图模合成方法。该方法通过分析上下级调度系统之间的关口电网，对分散在各调度系统的电网模型和厂站画面进行合并，形成一个完整、详细的电网描述。在此基础上，提出建立一个分散式调度图模合成的在线系统，实现全网分散维护、合并建模、统一监视。测试表明，该方法可以有效解决各级调度系统间的信息孤岛问题。

Composition of Decentralized Graphics and Model Based on CIM and SVG

In the dispatching system, the power network is in general monitored and controlled hierarchically. The power network model and SCADA information for each dispatching system are relatively independent and a sort of isolated information exists. Based on the common information model (CIM) standard and scalable vector graphics (SVG) format, a method of combining these decentralized graphics and model is presented. By analyzing the structure of the gateway power network between the superior dispatching system and each subordinate system, the method combines the decentralized models and graphics of each system to form a whole and detailed power network model. Accordingly, an online system for combining the decentralized distributed models and graphics is built to achieve decentralized maintenance, centralized modeling and unified monitoring of the whole network. The test results show that this method can resolve the problem of isolated information among the dispatching systems.
