Abstract

The invention discloses an offshore wind turbine generator load testing device and method. The device comprises wind measuring equipment, wave measuring equipment, flow measuring equipment, a strain gauge sensor, data collectors, an industrial personal computer and a wireless communication module. The wind measuring equipment, the wave measuring equipment, the flow measuring equipment and the strain gauge sensor are respectively connected with one data collector, and each data collector is connected with the industrial personal computer. The industrial personal computer is connected with the wireless communication module, and the wireless communication module is used for sending out data of the industrial personal computer in a wireless transmission mode. Besides wind, waves and flow serve as factors influencing the load of a fan, the load borne by the fan can be modeled more accurately, the influence of different factors on the load of the fan can be evaluated accurately, and therefore the load distribution of a wind turbine generator is evaluated accurately in the design stage to optimize the structural design of the fan.

Description

technical field [0001] The invention belongs to the technical field of load testing, and in particular relates to a load testing device and method for an offshore wind turbine. Background technique [0002] Wind turbine load calculation is an important link in the design, and the load calculation results are the input conditions for the design of the components of the wind turbine, which are related to the safety and reliability of the wind turbine. However, the load calculation cannot fully represent the actual operation of the wind turbine. In actual operation, there are more and more problems caused by the load of large components. Many problems such as blade breakage and transmission chain wear are the result of the load. Therefore, it is very important to grasp the load size and distribution of wind turbines in time for the life safety of wind turbines. [0003] The operating load of onshore wind turbines is mainly caused by the magnitude and change of the wind. The gr...
