Problems solved by technology

[0003] At present, both offshore wind power and wave energy power generation equipment have achieved rapid development, but they operate independently and cannot effectively utilize the good complementary characteristics of the two energies. Moreover, the towers of traditional offshore wind power are built on the seabed, and the high salinity of seawater As well as seawater wave and tidal movement, it is easy to cause corrosion and distortion of the tower, which seriously affects the service life of the tower, and the installation and maintenance costs of the tower are relatively high; although the mobile offshore wind power generation system can solve problems such as tower installation, However, the stable control of the wind power platform requires wind power to be adjusted, which greatly reduces the power generation of the wind power system
At the same time, most of the key components of the current wave power generation equipment are submerged in the water, and the base point of wave capture is easily fluctuated by waves, which seriously affects the efficiency of wave capture. At the same time, the airtightness of the equipment is high, and the transmission of wave energy also restricts wind power generation to some extent. and the promotion and application of wave energy systems

Abstract

The invention discloses a flexible direct-current transmission wind and wave hybrid power generation system. The flexible direct-current transmission wind and wave hybrid power generation system comprises a mouse cage type tower frame platform, a wind energy subsystem, a wave energy subsystem, a power regulation unit and a flexible direct-current power transmission station; wind power generation and wave energy power generation are combined, the characteristic that dynamic response of the wave energy subsystem is rapid is fully exerted, wind power generation fluctuation power restraining and tower frame platform inclination active regulation can be achieved, the mouse cage type tower frame platform supports the wind and wave hybrid power generation system, a rigid oval floating body passively regulates the inclination angle of a tower frame, the wave energy subsystem is inversely hung on a round platform, power generation and electric modes can be rapidly switched according to the station, and power grid scheduling power and tower frame inclination angle stability can be ensured; the power regulation unit achieves wind and wave maximum power capturing and power dual-way flowing; the flexible direct-current power transmission station finishes converging and feed of wind wave capturing power. Wind and power output power and tower frame inclination angle stability can be improved,the mounting and maintaining cost can be greatly reduced, and development of the wind and wave hybrid power generation system can be promoted.

Description

Technical field [0001] The invention discloses a flexible DC transmission wind and wave hybrid power generation system, which is a new type of power generation system that is applied to the vast ocean and provides electrical energy for remote islands, coastal areas and passing ships. Background technique [0002] With the increasingly serious global energy crisis and environmental pollution, new energies such as ocean wind and wave energy are favored by countries all over the world. my country also clearly proposes to increase the development of marine resources in the "National Marine Economic Planning and Development Outline", which will help my country’s economic development. Add new power. However, problems such as difficulty in power supply have greatly restricted the development and utilization of ocean-going resources. As clean energy, wind energy and wave energy have a huge amount of marine energy. At the same time, offshore wind energy and wave energy are naturally coupl...
