Abstract

The invention relates to a wind turbine generator blade online monitoring system and a work method thereof, and belongs to the field of wind power generation. The system comprises a laser sensor holder, laser sensors, a data acquisition device, a sensor power supply output interface, a tower footing optical fiber reserved interface, an optical fiber and a data storage and analysis device; the laser sensors are arranged on the outer wall of a tower in a surrounding manner through the laser sensor holder, the height between the laser sensors and the ground is larger than the heights between theblade tip positions and the ground when blades are vertically downward by 0.5 to 2 meters, the data acquisition device is connected with the laser sensors, the data acquisition device is connected with the tower footing optical fiber reserved interface and is connected with the data storage and analysis device through the optical fiber, and the sensor power supply output interface is connected with the laser sensors. Through setting of the system, blade icing, cracking, breaking, paddle angle inconsistency and the like are diagnosed, blade online monitoring and analysis functions can be achieved, happening of accidents like blade breakage can be avoided, and safe running of a wind turbine generator is ensured.

Description

technical field [0001] The invention relates to an on-line monitoring system and a working method for wind turbine blades, belonging to the field of wind power generation. Background technique [0002] Driven by the country's policy of vigorously developing wind power, the entire domestic wind power industry has developed rapidly in recent years. However, due to the late start of research on key technologies of wind power in my country and the dependence on foreign countries for the design and manufacturing technology of complete machines, the rapid development has also brought many problems. With the continuous development of wind power generation technology and increasing installed capacity, wind power, as a new type of energy, accounts for a higher and higher proportion in the global energy structure. However, the rapid growth of wind power has caused the wind power industry to face the problem of increasing operation and maintenance costs of wind turbines. The operation ...
