Stable and typhoon-resistant wind turbine generator system for floating wind farm

Abstract

The invention relates to a stable and typhoon-resistant wind turbine generator system for a floating wind farm. The stable and typhoon-resistant wind turbine generator system for the floating wind farm comprises an offshore platform and a plurality of wind turbine units arranged on the offshore platform; each wind turbine unit comprises a wind turbine generator system, a support tower, a hollow inverted cone and a cylindrical tank of which the interior is filled with seawater; each wind turbine generator system is installed on the top of the corresponding support tower, and the bottom of eachsupport tower is fixed to the bottom surface of the corresponding hollow inverted cone; each hollow inverted cone is arranged in the corresponding cylindrical tank, and floats on the seawater in the cylindrical tank; the height of each cylindrical tank is larger than the height of the offshore platform, and each cylindrical tank penetrates the offshore platform axially; and the side wall of each cylindrical tank is fixedly connected to the offshore platform, and provided with a water inlet/outlet which can be opened and closed. The stable and typhoon-resistant wind turbine generator system forthe floating wind farm has the advantages of stable operation of wind turbines, high typhoon resistance, low construction cost, and easy installation and maintenance.

Description

technical field [0001] The invention relates to the technical field of offshore wind farms, in particular to a stable and typhoon-resistant fan system for floating wind farms. Background technique [0002] There are often irregular typhoons and strong winds at the front of cold high pressure in winter along the coast of China. When the wind force reaches level 8 and above, the strong winds will have adverse effects on offshore facilities, and even damage the equipment of offshore facilities. [0003] An offshore platform is a truss structure that is above the sea and has a horizontal platform for production operations or other activities. Wind turbines can be installed on offshore platforms to generate electricity. However, under the influence of strong winds such as typhoons, the large swells and wind waves generated on the sea surface, as well as factors such as wind and current, cause the offshore platform to sway with different degrees of freedom, causing the power gene...

Problems solved by technology

However, under the influence of strong winds such as typhoons, large swells and wind waves generated on the sea surface, as well as factors such as wind and current, cause the offshore platform to shake with different degrees of freedom, causing the power generation fan on the platform to shake with an increase of 6 degrees of freedom.
