Construction of digital twin ecosystem for coal-fired generating units

Abstract

With the development of big data, cloud computing, Internet of things, digital twin and other technologies, the deep integration of these technologies with the energy industry is becoming the demand of production management progress, intelligent power generation has become the trend of development in energy industry.. This article gives an overview of the digital twin ecosystem of coal-fired generating units. The construction of the digital twin ecosystem is carried out from the overall architecture, and it is given a detailed introduction to DCS interface architecture, communication architecture. The digital twin ecosystem can realize real-time twins, predicting twins, simulating twins, and state evaluation, monitoring and early warning, fault diagnosis, optimization guidance, three-dimensional visualization and other functions, which can provide a predictable and visualized big data monitoring platform for real-time monitoring of the entire process of power plant operation, transparency of operation management, and timely discovery of equipment status.
