Laser technology for determining the geometry of a hydroelectric generator rotor under load
Laser technology for determining the geometry of the rotor of a hydroelectric generator under load, based on automated remote high-speed measurements through the ventilation channel of the stator using a semiconductor FMCW-lidar is described. The experimental model of the laser system was tested on an existing hydroelectric generator. Results of measurements of the geometry of a loaded rotor of acting hydroelectric generator No. 4 of the Sayano-Shushenskaya hydroelectric power station (type SVF/1285-42V4, 640 MW) have been obtained for the first time. The error of measurements made by this method based on laser technology in experimental form did not exceed 1%.
