Abstract

Despite the surge in popularity of new energy sources in recent years, the indispensability of thermal power plants remains unwavering. The steam turbine generator digital electro‐hydraulic (DEH) control system is a pivotal component in thermal power plants, directly influencing the safety, stability and efficiency of both the plant and the interconnected power grid. Therefore, for better monitoring and control of the DEH, it is necessary to conduct digital twin research on the DEH. This article presents a holistic approach to advancing the digital twin of DEH control systems, mainly including the construction of a dynamic mathematical model, comprehensive digital simulations under varying conditions, and the innovative development of a real‐time online simulation platform. Additionally, the integration of a three‐dimensional model enhances the depth and visualisation, providing a more immersive understanding of the DEH system's intricate dynamics. The successful implementation of this platform serves as a cornerstone, laying a robust foundation for the eventual establishment of the DEH digital twin system.
