Offshore wind and wave combined power generation device

Abstract

The invention discloses an offshore wind and wave combined power generation device. The offshore wind and wave combined power generation device comprises a large-megawatt horizontal-axis wind-driven generator, a floating damping pool foundation, a support, oscillating float type wave power generating equipment and a flexible mooring system; the floating damping pool foundation is fixed to a sea bed through the flexible mooring system; the large-megawatt horizontal-axis wind-driven generator and the oscillating float type wave power generating equipment are integrated on the floating damping pool foundation; multiple pieces of the oscillating float type wave power generating equipment are fixed to the support to form an array and are located in the hollow area of the floating damping pool foundation; the large-megawatt horizontal-axis wind-driven generator and the oscillating float type wave power generating equipment are electrically connected with a box-type transformer arranged inside the floating damping pool foundation; and an accumulator arranged inside the floating damping pool foundation is connected with the box-type transformer and is used as a back-up power supply for thelarge-megawatt horizontal-axis wind-driven generator. According to the offshore wind and wave combined power generation device, the intensive sea utilization efficiency can be improved, the equipmentequally-sharing cost can be reduced, and the comprehensive energy field incomes can be increased.

Description

technical field [0001] The invention relates to the technical field of offshore wind power generation and offshore wave power generation, in particular to an offshore wind-wave combined power generation device. Background technique [0002] Ocean energy is rich, including wind energy, wave energy, ocean current energy and other energy resources. In recent years, with the continuous iterative progress and relative maturity of various marine energy development technologies, some marine energy has entered the stage of large-scale development. At present, the development of domestic offshore wind resources is mainly concentrated in the offshore. , offshore wind resources will soon be fully developed and utilized, so people gradually turn their attention from offshore to deep sea with better wind resources, and floating foundations can be used in deep seas. Compared with traditional offshore fixed foundations, floating foundations Although it takes up more space, it requires les...

Problems solved by technology

However, as a new form of marine energy development, its development is relatively slow due to limitations in technology and resource conditions.

At present, the cost per unit of electricity of wave power generation projects is relatively high, and the conditions for large-scale commercial development are not yet available in China
