Online expansion monitoring method, system and equipment for turbine bearing seat and medium

Abstract

The invention provides a steam turbine bearing pedestal online expansion monitoring method, system and device and a medium. The steam turbine bearing pedestal online expansion monitoring method comprises the following steps of 1, collecting surface point cloud data corresponding to each bearing pedestal of a steam turbine; step 2, inputting the obtained surface point cloud data into a preset bearing seat expansion algorithm model to obtain an expansion amount corresponding to each bearing seat; 3, the expansion dynamic state of each bearing seat is monitored through the obtained expansion amount; the invention provides panoramic monitoring of the dynamic change trend and early warning of the bearing seat of the steam turbine generator unit, and solves the defect that the expansion and contraction states of the bearing seat of the existing steam turbine are not effectively monitored, so that when the steam turbine generator unit is abnormal, the abnormal reason cannot be accurately analyzed.
