为适应电厂企业各类自动化与信息化系统不断拓广的互连、集成及全方位开放需求,文中提出了一种用于电厂DEH/DCS/SIS等系统设计的平台建设技术。该技术基于分组、分层、分块的平台体系及构件化结构。在构造应用系统及与电厂各系统的互连通信中,此平台技术体现更大的开放度及持续可扩性。 In order to meet the needs of interconnection, integration and all-round openness of various automation and information systems of power plant enterprises, this paper presents a platform construction technology for system design of power plant DEH / DCS / SIS. The technology is based on grouping, layering, and partitioning of the platform architecture and component architecture. This platform technology demonstrates greater openness and continued scalability in the construction of application systems and in the interconnection of communications with various systems in power plants.
