The invention discloses a boiler on-line three-dimensional
thermal expansion monitoring system based on a deep peak regulation working condition, relates to the field of power
plant boiler detection equipment, and aims at the core pain points that under the deep peak regulation working condition,
unit operation working condition fluctuation is large, load deviates from a design value, and vibration and temperature interference is remarkable. A
data acquisition module, a working condition identification module, a three-dimensional measurement module, a dynamic compensation module, a depth prediction module, a digital twinning module, an
intelligent control module and a 5G remote monitoring module are integrated, and a whole-
process architecture of working condition identification, three-dimensional accurate measurement, multi-source error compensation,
trend prediction, closed-
loop control and
remote operation and maintenance is adopted. Real-time monitoring of three-direction
thermal expansion displacement of the boiler pressure-bearing component, expansion
trend prediction in a deep peak regulation scene and intelligent optimization of operation parameters are realized, and the problems of low monitoring precision, weak prediction capability and poor anti-interference performance in the deep peak regulation scene in the prior art are effectively solved. And the safety, economical efficiency and stability of boiler operation under the deep peak regulation working condition are remarkably improved.
