DCS Translation Tool: Faster and Better than Ever

摘要

CAE's constant push to advance power plant simulation practices involves continued investment in our technologies. This commitment has yielded many advances in our simulation technologies and tools to provide faster maintenance updates, easier process updates and higher fidelity models for power plant simulators. Through this quest, a comprehensive, self-contained and user-friendly DCS translation tool for plant control system emulation was created. The translation tool converts an ABB Advant AC160 and/or AC450 control system, used in both gas turbine-based, fossil and nuclear power plants, into Linux or Windows-based ROSE? simulation schematics. The translation for a full combined-cycle gas turbine (CCGT) plant that comprises more than 5,300 function plans distributed over 15 nodes is processed in less than five hours on a dual 2.8Ghz Xeon Linux platform in comparison to the 12 hours required by CAE's previous translation tool. The translation process, using the plant configuration files, includes the parsing of the control algorithms, the databases, the graphic and the interconnection between nodes. A Linux or Windows API is then used to automatically populate the ROSE? database. Without such a translation, tool or if "stimulation" of real control system is not feasible or too costly, simulation of the DCS manually takes months of error prone manual coding. The translation can be performed for all the nodes constituting the configuration files of the whole plant DCS, or in order to provide faster maintenance updates and easier process updates, partial builds are possible at 3 levels: a. single schematic updates, b. multi-schematic updates and c. single node updates based on the user inputs into the Graphical User Interface.
