Offshore floating type wind generator controlled by tuned liquid column damper

Abstract

The invention provides an offshore floating type wind generator controlled by a tuned liquid column damper, and belongs to the technical field of offshore wind power generation. The offshore floating type wind generator controlled by the tuned liquid column damper comprises a wind generator body, a tension leg platform and a mooring mechanism, wherein the tension leg platform supports the wind generator body. The mooring mechanism fixes the tension leg platform in a seabed rock soil layer, the tension leg platform comprises a deck platform, a tuned liquid column damping device and a floating body, wherein the tuned liquid column damping device is arranged in the deck platform, the bottom of the deck platform is connected with the floating body, the bottom of the floating body is connected with the mooring mechanism, buoyancy force borne by the tension leg platform is larger than gravity force borne by the tension leg platform, the difference value between the buoyancy force and the gravity force is balanced by tension of the mooring mechanism, buoyancy force of the tension leg platform is acquired by multiplying volume of displacement of the tension leg platform by seawater specific gravity, and gravity force of the tension leg platform is acquired by adding and summing the weights of subitems of the tension leg platform. The offshore floating type wind generator controlled by the tuned liquid column damper is small in system whole motion amplitude, low in vibration intensity of local members, and long in the fatigue life of structural members.

AI Technical Summary

Benefits of technology

The present technology allows for smaller movements that are more stable than previous designs while still maintaining its effectiveness over time.

Problems solved by technology

This patented technical problem addressed in the patents relates to improving the stability and reducing noise levels experienced during operation at near shore locations due to factors like tides or ocean currents caused by strong forces acting upon offshoys used for generating electricity. Existing solutions involve adding anchors to stabilize the platforms' position under heavy loadings while minimizing their movements over time. These techniques result in significant increases in weight and cost compared to traditional methods.
