Abstract: Intelligent power generation technology is an important means to promote the competitiveness of coal-fired power plants in power generation field. The policy and industrial background of the intelligent coal-fired power generation are analyzed in this paper, and the architecture of the intelligent coal-fired power generation technology is proposed by considering the intelligent equipment layer, the intelligent operation and maintenance layer and the intelligent management layer of the smart power plants. Six key technologies of intelligent coal-fired power generation are presented, including the smart measurement and control, the smart operation optimization and energy conservation, the life cycle equipment management, the intelligent robot technology, the intelligent operation and management, the intelligent interaction and security, etc. The latest progresses are summarized and can be used as a reference for the future development of the intelligent coal-fired intelligent power generation.
