An offshore wind power and ocean tidal current energy combined power generation device

Abstract

The invention provides an offshore wind power and ocean tidal current energy combined power generation device. The offshore wind power and ocean tidal current energy combined power generation device mainly comprises an offshore wind power generation subsystem, a tidal current energy power generation subsystem, a brace foundation system and an electric energy transmission system. The offshore wind power generation subsystem is fixed above the sea level through the brace foundation system. The brace foundation system is in a single-pile type foundation form. The tidal current energy power generation subsystem is installed beside the brace foundation system through an L-shaped supporting frame. The electric energy transmission system transmits electricity generated by offshore wind power generators and tidal current energy power generators to a power grid together. Ocean limited space resources are fully utilized; the ocean resource utilization rate is increased; the economic benefits of an offshore wind plant are increased; the tidal current energy power generation subsystem has the yawing function, tidal current energy can be fully acquired, and the power generation rate of equipment is increased.

Description

technical field [0001] The invention relates to the technical field of offshore wind power and ocean energy power generation, in particular to an offshore wind power and ocean tidal current energy combined power generation device. Background technique [0002] With the continuous growth of domestic demand for energy, non-renewable resources such as oil are facing a trend of depletion, and renewable energy has attracted more and more attention and attention. As a new type of pollution-free and clean industry, offshore wind farms have begun to be established in my country, and offshore wind power technology has begun to be widely used. The tidal current energy, which is also rich in reserves and widely distributed, is also favored by various countries, and has great development prospects and commercial value. Since both power generation devices are located in the ocean, combining offshore wind power and tidal current energy power generation devices can effectively use limited...

AI Technical Summary

Problems solved by technology

[0003] Since most of the traditional tidal current power generation equipment adopts the blade structure and the installation position is relatively fixed, when the tidal flow direction changes, the equipment cannot fully obtain energy, which reduces the power generation efficiency of the equipment

In addition, the three commonly used fixing methods for the carrier of tidal current energy generation equipment - pile type, floating type and subsea type, each have their disadvantages: the subsea type has a low flow rate near the bottom, which is not easy to maintain and recycle; the floating type Anchoring is greatly affected by wind and waves, and the stability is not good; although the pile type is relatively stable, the cost is high
