On the basis of digital power plant

the model foundation of intelligent power plant is built

and a new functional framework of intelligent power plant is put forward. This technology focuses on the integration of artificial intelligence technology and power plant professional mechanism model

and studies the key technologies including the mechanism modeling and real-time simulation of power plant

boiler combustion optimization based on three-dimensional visualization

intelligent control of boiler and environmental protection island

intelligent energy management

intelligent early warning and preventive maintenance of equipment

and so on. These technologies have been successfully applied in a power plant. The black screen operation and one key intelligent start-up and shutdown of the boiler and the environmental protection island have been realized. The thermal efficiency of the boiler has increased by 0.5%. The leakage accident of the boiler tube has been basically eliminated. Through the application of these technologies

the intelligent management and control of power plants has been realized

and outstanding energy-saving and safe production effects have been achieved

which has obvious popularization value.
