Title:
SYSTEM FOR MONITORING OPERATING STATE OF BLADES OF OFFSHORE WIND TURBINE
Document Type and Number:
WIPO Patent Application WO/2018/082373
Kind Code:
A1
Abstract:
A system for monitoring the operating state of blades of an offshore wind turbine, comprising: a blade frequency acquisition device (11) that acquires a blade frequency of a wind turbine; a synchronous drive circuit (14) that receives the blade frequency and outputs two identical drive signals having a frequency which is an integral multiple of the blade frequency; a light emitting device (12) that receives the drive signals, and emits light having a frequency identical to the frequency of the drive signals to the rotating blades (36); a thermal image acquisition device (13) that receives the drive signals, and acquires a thermal image at a frequency identical to that of the drive signals to obtain thermal image data; and an analysis terminal (15) that receives the thermal image data and performs failure analysis. The blade frequency acquisition device (11) is connected to the synchronous drive circuit (14). The synchronous drive circuit (14) is connected to the light emitting device (12) and the thermal image acquisition device (13). The thermal image acquisition device (13) is connected to the analysis terminal (15). The system for monitoring the operating state of blades of an offshore wind turbine can timely monitor the blade state of a wind turbine.
