Abstract

Abstract:

The national strategy of "carbon peaking and carbon neutralization" and the industry consensus of "reducing cost, improving quality and increasing efficiency" require the digital transformation of thermal power units. The application of digital twin in the digital transformation of thermal power units is researched, the four-dimensional model and five internal relationships of thermal power unit digital twin system are proposed, the functions, architecture and objectives of system scheduling platform and five kinds of services, intelligent development, intelligent perception, intelligent evaluation, intelligent optimization and intelligent security are introduced, and the three development stages of the system are prospected. It is expected to improve the measurement, control, scheduling and management of thermal power units, consolidate the strategic position of thermal power supply and peak shaving, and realize the digital transformation goals of intelligent control, intelligent management, energy saving, low carbon and environmental protection.

Key words: digital twin, thermal power unit, digital transformation, digital twin service, carbon peaking and carbon neutralization
