Problems solved by technology

In order to increase the single-unit power generation capacity of offshore wind turbines, larger wind turbines are usually used. Correspondingly, the size and weight of fan impellers, generators, speed reducers and other components of larger wind turbines are larger. When installing such a large-scale wind turbine, the hoisting of the wind turbine is more difficult, and a lifting device with a larger lifting capacity is required, the installation cost is higher, and the cost of the large-scale wind turbine itself is relatively high; in order to be able to safely carry the above-mentioned Wind turbines will inevitably increase the size and strength of the foundation and tower, making the cost of offshore wind turbines with this structure higher

Abstract

The invention relates to the technical field of offshore wind power, in particular to an offshore wind generating set. The offshore wind generating set comprises a foundation, a tower drum, a fan impeller, a generator, a fan converter, a transformer and an ocean energy generating device, wherein the ocean energy generating device is fixed on the foundation; an electric quantity output end of the ocean energy generating device is connected with an electric quantity input end of the transformer. The offshore wind generating set with the structure can have high generating capacity without adopting a large-model wind generating set, is easy to lift without a lifting appliance with large lifting weight and is low in installation cost; and the size and the strength of the foundation and the tower drum do not need to be improved and the cost of the offshore wind generating set can be reduced.

Description

technical field [0001] The invention relates to the technical field of offshore wind power, in particular to an offshore wind power generating set with relatively large generating capacity. Background technique [0002] With the increasingly prominent social energy issues, climate issues, and environmental issues, the utilization of renewable resources has been paid more and more attention. Wind power has the advantages of abundant resources, good environmental benefits, high level of industrialization, and relatively low cost of power generation, and has become an important way to utilize renewable resources. [0003] A wind turbine is a power machine that converts wind energy into mechanical energy. The wind turbine uses wind power to drive the blades of the wind wheel to rotate, and then increases the speed of rotation through a speed increaser to drive the generator to generate electricity. [0004] Offshore wind power has the advantages of large reserves of wind energy...
