Offshore semi-submersible wind energy and wave energy integrated power generation equipment

Abstract

The invention belongs to the technical field of ocean renewable energy utilization, and discloses offshore semi-submersible wind energy and wave energy integrated power generation equipment. The integrated power generation equipment comprises a wind energy power generation mechanism, a semi-submersible platform and a plurality of wave energy power generation mechanisms, wherein the wind power generation mechanism is used for wind power generation and arranged on the semi-submersible platform; the plurality of wave energy power generation mechanisms are separately arranged on the semi-submersible platform and used for consuming wave energy received by the integrated power generation equipment to generate power; when the integrated power generation equipment vibrates under the action of waveenergy, the wave energy power generation mechanisms consume the wave energy to generate electricity as well as elastic deformation to store energy while limiting the movement of the semi-submersibleplatform; and after energy storage is finished, the wave energy power generation mechanisms generate power through an elastic restoring force, so that the vibration amplitude of the integrated power generation equipment is reduced while power generation is carried out by consuming wave energy received by the integrated power generation equipment. According to the integrated power generation equipment, the power generation efficiency and stability are improved, and the practicability is higher.

Description

technical field [0001] The invention belongs to the technical field related to the utilization of marine renewable energy, and more specifically relates to an offshore semi-submersible wind energy and wave energy integrated power generation equipment. Background technique [0002] With the rapid development of the world economy, the demand for energy continues to increase, the reduction of non-renewable energy sources such as petroleum is accelerating, and the massive consumption of fossil energy has also caused a series of environmental problems. As a clean renewable energy source, wind energy can be well solved The problems of traditional energy shortage and environmental pollution in today's world have been paid more and more attention by people. At present, domestic wind power projects are mainly concentrated on land and shallow sea areas, but the wind resources in deep sea areas are more abundant than land and offshore areas, and the wind speed is higher and more stable...

AI Technical Summary

Problems solved by technology

Traditional semi-submersible foundations will still produce large motion responses in complex deep-sea areas, which will aggravate the vibration of the platform and reduce the stability of the system, thereby reducing the power generation efficiency of the wind turbine
