Linking Hydraulic Network Models and SCADA Systems: The ABCs of System Integration 连接液压网络模型和SCADA系统:系统集成的ABCs
发布日期: 1994-01-01
已为德克萨斯州普莱诺市开发了一个集成包,包括一个联合水力模拟模型和一个SCADA系统。集成系统是更大控制模型的一部分,Plano系统运营商使用该模型控制运营成本,利用最先进的控制和遥测设备,并改善整体运营。描述24小时内储罐液位和泵特性的信息由SCADA系统收集和存储。这些信息以特定格式写入文件。 控制模型从SCADA系统复制文件,提取储罐液位和泵性能的数据,并将该信息写入与KYPIPE兼容的数据文件。控制模型还使用SCADA在质量平衡方案中收集的数据来确定短期需求预测。使用本文所述的集成系统的优点是,系统操作员无需为了分析场景而对水力模型进行麻烦的更改。相反,操作员可以专注于模拟的结果。 在控制模型框架内使用时,操作员可以启动模拟,以制定有效的操作策略,而无需担心数据如何从一个系统传输到另一个系统。
An integrated package has been developed for the City of Plano, Texas, consisting of a combined hydraulic simulation model and a SCADA system. The integrated system is part of a larger control model which is used by Plano system operators to control operating costs, utilize state of the art control and telemetry equipment, and improve overall operations. Information describing tank levels and pump characteristics for a 24-hour period is gathered and stored by the SCADA system. This information is written to a file with a specific format. The control model copies the file from the SCADA system, extracts data on tank levels and pump performance, and writes this information to a KYPIPE-compatible data file. The control model also uses SCADA collected data in a mass-balance scheme to determine short-term demand forecasts. The advantage of using an integrated system such as the one described in this paper is that it eliminates the need for system operators to make bothersome changes to a hydraulic model in order to analyze a scenario. Instead, operators are able to focus on the results of the simulation. When used within the framework of a control model, operators can initiate a simulation to develop efficient operating policies without worrying how data is transferred from one system to another.
