Description

technical field [0001] The invention relates to a device for generating electricity by utilizing natural energy, in particular to a wave energy auxiliary power generation device for a floating offshore wind farm. Background technique [0002] There are abundant energy stored in the ocean, among which wind energy and wave energy are inexhaustible green renewable energy. At present, the power generation of a single offshore wind turbine has reached the MW level, and the further away from the coast, the greater the wind speed. In the future, offshore wind power will develop towards sea areas farther offshore. Deep-sea wind power generally adopts a floating floating platform, and the wind turbine is installed on the upper surface of the floating platform. However, the floating platform is easily affected by waves and will sway and heave. The power output of the wind turbine is unstable due to vibration, and the output power is easy to fluctuate. lead to grid connection difficul...

AI Technical Summary

Problems solved by technology

Among them, both the tension leg type and the barge type have a platform floating on the sea surface, which has a large contact area with the sea surface, is greatly affected by waves, has poor stability, and even the wind turbine may overturn due to the high center of gravity

Although the Spar type does not have a buoy, it needs a buoy that extends below the sea surface. It is difficult to guarantee the strength of the slender buoy, and it is also difficult to produce and transport, and the economy is poor.

[0005] In terms of wave energy utilization, due to its low energy density, high volatility, instability, and low conversion efficiency, if wave energy is used alone for power generation, it is necessary to lay wave energy conversion devices on a large area. Even so, considering wave energy energy conversion The power generation efficiency of the device is low, and it takes up a lot of space. It needs large-scale utilization to obtain effective benefits, and its practicability is also poor

The above problems have led to a decline in the reliability and economy of ocean energy utilization devices.
