AI Technical Summary
Existing technologies cannot effectively provide early warning of excessive steam flow in high-temperature and high-pressure steam pipelines, leading to post-event maintenance. They are also unable to adapt to the extreme environment of ultra-high parameter coal-fired power units, affecting the safe and reliable operation of pipelines.
By acquiring design data of ultra-high parameter coal-fired power units, a variable operating condition model of the thermal system and a geometric model of the full-scale pipeline and fitting system are established. A flow field database is constructed by combining fluid dynamics analysis, a neural network model is trained, and measured parameters are used to judge overspeed risk and regulate steam flow for early warning.
It enables precise early warning of steam flow overspeed in high-temperature and high-pressure steam pipelines, improving the accuracy and timeliness of early warning, ensuring the safe and reliable operation of pipelines, and reducing operation and maintenance costs and safety hazards.
