Offshore wind turbine simulation experiment device

Abstract

The invention provides an offshore wind turbine simulation experiment device. The offshore wind turbine simulation experiment device comprises a wind wheel, a power mechanism used for driving the wind wheel to rotate and a transmission mechanism used for transmitting power, wherein the transmission mechanism drives the wind wheel to rotate through a rotating shaft, and the rotating shaft is installed on a base through a supporting seat. The offshore wind turbine simulation experiment device further comprises a vibration excitation mechanism used for simulating generated environmental stress, a data collection mechanism used for collecting experimental data of each component and a data analysis mechanism used for processing the experimental data, wherein the vibration excitation mechanism comprises a horizontal vibration exciter capable of adjusting the contact distance in all directions and a vertical vibration exciter controlled by excitation signal equipment. The offshore wind turbine simulation experiment device is formed by overall decreasing an actual size according to a certain proportion, and the working state of an actual offshore wind turbine can be accurately restored. An experimental environment obtained after the combination of the horizontal vibration exciter and the vertical vibration exciter is more in accord with the complex experimental environment on the sea, and the experimental data obtained after excitation simulation are more in accord with the actual working condition of the offshore wind turbine.

Description

technical field [0001] The invention relates to an experimental device for teaching or scientific research, in particular to an offshore wind power generator simulation experimental device. Background technique [0002] In today's increasingly scarce traditional energy sources, people are beginning to seek and develop various green renewable energy sources to replace traditional energy sources such as petroleum and diesel. Among them, wind energy is a relatively common renewable energy with the advantages of zero pollution, which can effectively save traditional resources and prevent environmental pollution. The construction period of wind power generation projects is short and flexible, which is convenient for large-scale development, and Good development potential. [0003] Compared with land wind energy, offshore wind energy has the advantages of high wind speed, low noise, and does not occupy land, and is less disturbed by environmental problems such as landscapes, ...

AI Technical Summary

Problems solved by technology

[0006] The above-mentioned utility model provides a dual-purpose wind turbine experimental device that can only collect the data after the experiment, but cannot obtain the excitation signal, and cannot make effective comparisons during the experiment, and the results obtained from the experimental analysis are not comprehensive.

Moreover, when simulating sea wind power generation, the above-mentioned utility model only considered the influence of sea waves, and did not fully consider the impact of the tower being excited on the overall experiment.
