Offshore wind power and vertical axis type tidal current energy combined power generation device

Abstract

The invention discloses an offshore wind power and vertical axis type tidal current energy combined power generation device. The offshore wind power and vertical axis type tidal current energy combined power generation device mainly comprises an offshore wind power generation subsystem, a tidal current energy power generation subsystem, a supporting foundation system, an electric energy conveyingsystem and a control system; the offshore wind power generation subsystem adopts a common horizontal axis type, and a generator is a permanent magnet direct current generator; the tidal current energypower generation subsystem adopts a vertical axis type which develops rapidly in recent years; the supporting foundation system is a single-pile type foundation, the wind power generation subsystem and the tidal current energy power generation subsystem share one supporting foundation pile, and the bottom of the supporting pile extends into the seabed to be fixed; the control system plays a rolein real-time communication and controlling the working states of all the subsystems; and the electric energy conveying system transmits electricity generated by the offshore wind power generator and atidal current generator to a power grid. The offshore wind power and vertical axis type tidal current energy combined power generation device has the advantages that clean and efficient marine resources can be fully excavated, the utilization rate of the marine resources can be increased, the power generation rate of the device can be increased, the construction cost and the maintenance cost canbe lowered, the service life can be prolonged, and the economic benefits of offshore wind power plants can be increased.

Description

technical field [0001] The invention belongs to the technical field of offshore wind power and ocean energy power generation, in particular to an offshore wind power and vertical-axis tidal current energy combined power generation device. Background technique [0002] In the past 20 years, driven by the energy crisis of fossil fuels and the pressure of environmental change, renewable new energy has attracted more and more attention around the world. my country is implementing development strategies such as marine resource development and renewable energy. The development and utilization of marine energy will be an important part of my country's future energy structure. my country's offshore wind power has also begun large-scale pre-construction projects. Offshore wind power technology has begun to be widely used and has great development prospects in the future. On the other hand, there are strong tidal currents in the bay mouth and waterways between islands, which have bro...
