Abstract

The invention provides a single-pile-based wind energy-wave energy-tidal energy integrated power generation system and belongs to the technical field of ocean renewable energy utilization. Wind energy, wave energy and tidal energy share a supporting structure and a power transmission system. An integration system integrating wind energy, oscillating water column type wave energy and horizontal axis tidal energy is established in ocean through the single-pile type supporting structure to form the integrated power generation system. The integrated power generation system can make full use of offshore renewable resources, so that the purposes of increasing the utilization rate of a single pile foundation and reducing the total power generation cost of the integration system are achieved, theoverall economic efficiency of an offshore wind plant is improved, and the wind energy, wave energy and tidal energy power generation cost is reduced. The novel fixed wind energy-wave energy-tidal energy integrated power generation system increases the effective utilization rate of a sea area, reduces the construction cost and maintenance cost, makes full use of the existing mature draught fan technology, promotes commercial application of wave energy devices and tidal energy devices and is a reliable offshore renewable energy power generation platform.

Description

technical field [0001] The invention belongs to the technical field of marine renewable energy utilization, and in particular relates to a wind energy-wave energy-tidal current energy combined power generation device, an integrated power generation system based on a single pile structure that combines wind energy, oscillating water column wave energy and tidal current energy . Background technique [0002] Offshore wind energy, wave energy and tidal current energy are all marine renewable energy sources. Wind power is currently the most promising renewable energy source for large-scale development. Offshore wind power has become a new direction of international wind power development and has attracted the attention of all countries. The development of offshore wind energy is of great significance to my country's control of atmospheric smog and adjustment of energy structure. Wind-rich waters are often also rich in wave energy. Tidal current power generation is basically ...
