Embodiment 1

[0025] see Figure 1-Figure 3 , is a floating offshore wind power generator system 100 provided in the first embodiment of the present invention. The floating offshore wind power generator system 100 includes a mooring system and a structural vibration control system 30. The tensioned mooring chain group 33 in the lower mooring system acts as a limiter, and the structural vibration control system 30 in the upper layer acts as a limiter. The active control of the load-displacement controller 321 in the semi-tensioned mooring chain group 32 in the control system 30 plays a role in suppressing the overall vibration of the offshore wind power generation assembly 20, so that the entire floating offshore wind power generator can be effectively controlled The stability of the system 100 within a certain sea area provides more stable support for the offshore wind power generation components 20 with large single-unit capacity, and improves the working efficiency and service life of the...

Embodiment 2

[0036] see Figure 4-6 , is a floating offshore wind power generator system 200 provided in the second embodiment of the present invention. The difference between the second embodiment and the first embodiment is that the floating offshore wind power generator system 200 not only includes a mooring system and a structural vibration control system 30 , but also includes three sets of ocean current power generation components 40 arranged below the foundation buoy 10 . The ocean current power generation module 40 located below the sea level works together with the offshore wind power generation module 20 arranged above the sea level, and the two cooperate with each other to generate electricity by using the wind energy at sea and the ocean current at the bottom of the sea at the same time, which has great economic value. Moreover, the motion response of the entire floating offshore wind power generator system 200 can be suppressed by adding the ocean current power generation comp...

Abstract

The invention provides a floating offshore wind driven generator system. The floating offshore wind driven generator system comprises a foundation float bowl and an offshore wind power generation assembly, and further comprises a mooring system and a structure vibration control system, the mooring system comprises multiple tensioning type mooring chain sets fixed to the foundation float bowl, thestructure vibration control system comprises a first connecting platform mounted on a fan tower and multiple semi-tensioning type mooring chain sets fixed to the first connecting platform, according to the floating offshore wind driven generator system, the structure vibration control system is added, multiple supporting points special for the offshore wind power generation assembly are added, through the structure vibration control system, the environment load and system whole vibration acting on the offshore wind power generation assembly can be effectively absorbed, the whole motion response of the floating offshore wind driven generator system can be reduced, the stability of the floating offshore wind driven generator system is improved, the power generation efficiency of the offshorewind power generation assembly can be improved, and the service life of the offshore wind power generation assembly can be prolonged.

Description

technical field [0001] The invention relates to the technical field of marine renewable energy utilization, in particular to a floating offshore wind power generator system. Background technique [0002] The sea is rich in wind energy and ocean current resources, which are the main directions for the development and utilization of new energy. At present, offshore wind power development is mainly concentrated in shallow water areas, and wind turbines mostly use fixed foundations. With the deepening of development, offshore wind power development will develop in offshore deep water areas. In the development of deep water wind power, the fixed foundation has lost its superiority, and the floating foundation has become an ideal support foundation for wind turbines. [0003] High technical requirements and expensive construction and installation costs limit the popularization and application of offshore wind turbines with floating foundations. In order to improve the economics...
