以电厂全生命周期管理为核心，采用先进的设计、管理和控制技术，构建智能化、数字化、透明化的大型火电厂，代表了当今火电厂管理和控制一体化发展的最高水平。同时，在数字化电厂的发展过程中，也经历了从局部数字化到完整数字化的过程。在以往提出的数字化电厂方案中，基本上是特指某一部分的数字化，或者是数字化系统的某个功能。通过对火电厂全生命周期管理概念的最新解析，以及对数字化工程系统、数字化控制系统和数字化管理系统的定义、分析和研究，提出了全新的数字化电厂的全景架构和方案设想。

By focusing on the whole life cycle management of power plant and adopting advanced technologies in design, management and control, an intelligent, digital and visualized large power plant will be constructed, which represents the top level of integration system of management and control in the current power plants. In the development of digital power plant, it also experiences a process from part digitization to whole digitization. In the previous schemes of digital power plant, digitalization basically only means a part, or one function of the digital system. In this paper the panoramic architecture and scheme assumption of new digital power plant are proposed, based on the analysis of whole life-cycle management in power plant, and the definition, analysis and research of digital engineering system, digital control system and digital management system.
