The intelligent control system(ICS) is an important foundation for achieving the goal of smart energy construction during the “14th Five-Year” Plan. Starting from the actual needs of data

algorithms and hash rate for intelligent applications in thermal power plants

this paper further expands the hardware and network on the basis of the distributed control system(DCS) to form an ICS. Moreover

based on the fundamental goals

connection relationships and information flow process of different applications

the functional architecture of the ICS is proposed

namely advanced detection

intelligent control

autonomous decision-making

and intelligent interaction.Under this framework

this paper details the key technologies of ICS in thermal power plants

which is of great significance to guiding the construction of ICSs of thermal power plants and developing a smart energy system.
