以虚拟分散控制系统(DCS)仿真控制技术和系统的相似度理论为基础,利用监控信息系统(SIS)和仿真系统的互联条件,开发了用于大型发电厂真实数据和仿真数据的比较系统。采用系统的相似度理论实现了相似度的算法,利用实时和关系数据库技术对数据进行管理和计算,同时运用ADO(activeX data object)接口技术方便地实现了数据库和应用程序的数据连接。
Based on the theory of similarity control of virtual distributed control system (DCS) and system, a comparison system for real data and simulation data of large power plant was developed based on the interconnection between monitoring information system (SIS) and simulation system. The algorithm of similarity is implemented by using the similarity theory of the system. The data is managed and calculated by using the real-time and relational database technology, and the data connection between the database and the application is conveniently realized by using the ActiveX data object (ADO) interface technology.
