Abstract

The invention discloses an axial force dynamic monitoring device of a low-wind-speed wind turbine generator, a monitoring method thereof and an unit, and belongs to the field of wind turbine generators. The monitoring device comprises strain gage sets, a data acquirer, a data transmission device and a server; two strain gage sets are provided, and are mounted on an inner cavity on the front edge of a cylindrical section near the roots of blades by different distances in the axial directions of the blades; each strain gage set comprises two strain gages oppositely mounted on two sides of the inner cavity on the front edge up and down; the data acquirer is used for acquiring measuring data information of the strain gage sets; the data transmission device is used for transmitting acquired information to the server; and the server is used for analyzing and judging acquired information and comparing the calculated result with a preset alarm value to give an indication if an alarm is given.The monitoring device can be used for effectively monitoring axial force of the wind turbine generator, meanwhile, can monitor the operating state of the blades, and can give the alarm indication through comparison with the preset alarm value.

Description

technical field [0001] The invention relates to the field of wind turbines, in particular to a dynamic monitoring device for the axial force of a low wind speed wind turbine, a monitoring method thereof, and a unit. Background technique [0002] In a wind turbine, the unit relies on the blades to absorb wind energy, convert the wind energy into mechanical energy, and then convert the mechanical energy into electrical energy and send it out through the grid. During the entire operation of the unit, the blade is the main force-bearing component, and the force on the blade rotation plane will eventually be converted into an axial force to act on the unit. Therefore, real-time monitoring of the axial force is helpful to monitor the operating state of the unit and ensure that the unit operates under normal load conditions. [0003] In the prior art, there is no real-time monitoring technology for the axial force of the wind turbine, but only related monitoring or reliability cal...
