Title:
GENERATOR DEFORMATION MONITORING METHOD
Document Type and Number:
WIPO Patent Application WO/2024/027721
Kind Code:
A1
Abstract:
The present invention relates to a generator deformation monitoring method. The method comprises: S1. prior to a generator being pressurized, determining a monitoring position and a monitoring station; S2. by means of a monitoring apparatus arranged at the monitoring station, obtaining position information of the monitoring position, and using same as first monitoring position information; S3. constructing a standard spatial coordinate system, and converting the first monitoring position information to first coordinate data under the standard spatial coordinate system; S4. following generator pressurization, again obtaining position information of the monitoring position, and using same as second monitoring position information; S5. fitting the second monitoring position information into the standard spatial coordinate system, and obtaining second coordinate data; S6. comparing the first coordinate data against the second coordinate data to obtain a deformation monitoring result. The present invention effectively obtains changes to a generator monitoring position in a three-dimensional space, grasps generator deformation patterns before and after pressurization, and collects numerous types of measurement data with relatively little on-site intervention, ensuring the normal operation of the unit, and improving device reliability.
