Novel stationary type wind energy and wave energy integrated power generation system

Abstract

The invention relates to a novel stationary type wind energy and wave energy integrated power generation system, belonging to the technical field of marine renewable energy utilization. A single pile of a fan is fixedly connected with a sleeve near the sea level, and an oscillating wave energy power generation deice is connected with the sleeve positioned near the sea level through a fastening device. Two fastening devices are arranged on the sleeve. The wave energy power generation deice comprises a PTO energy catching system and floaters, and the floaters are symmetrically arranged on the two sides of a single pile foundation and reaches the first fastening device through hinges. The PTO energy catching system is hinged between the floaters and the second fastening device and is vertical to the floaters. The PTO energy catching system converts linear piston motion to electricity through a linear generator and is connected with the power transmission system of a wind driven generator. The power generation system improves the effective utilization ratio of sea area, reduces the construction cost and maintenance cost, makes full use of the existing mature fan technology, promotes the commercial application of a wave energy device, and is a reliable marine 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 integrated power generation system, an integrated power generation system combining wind energy and wave energy based on a single pile structure. Background technique [0002] 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. my country's eastern coastal areas are rich in offshore wind energy resources. The development potential of offshore wind power at a water depth of 5-25 meters and a height of 50 meters is about 200 million kilowatts. Compared with land, there are more abundant wind res...

AI Technical Summary

Problems solved by technology

[0003] Wind power generation is relatively mature not only in the world but also in my country, while wave power generation devices have low energy conversion efficiency and high unit power generation costs, which limit their commercialization to a certain extent.
