Wind energy-wave energy combined power generation device and power generation method based on offshore floating platform

Abstract

The invention discloses a wind energy-wave energy combined power generation device and method based on an offshore floating platform and belongs to the technical field of offshore renewable energy source utilization. The problem about sufficient utilization of sea renewable energy sources is solved. The wind energy-wave energy combined power generation device comprises a wind power generator system, a floating platform system, a wave energy power generation system and a mooring system. The wind power generator system and the wave energy power generation system are installed on the floating platform system. The mooring system comprises an anchor chain and a seabed anchor. One end of the anchor chain is fixedly connected to the floating platform system, and the other end of the anchor chainis connected with the seabed anchor and is connected with a seabed through the seabed anchor. The wind energy-wave energy combined power generation device and method have the beneficial effects that the overall power generation performance is improved, the total power generation amount is increased, sea renewable energy is effectively utilized, the investment cost is reduced, and business-like application is accelerated.

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 combined power generation device based on an offshore floating platform, which is based on a new type of floating platform and combines wind energy with oscillating water column wave energy combined power generation unit. Background technique [0002] With the continuous increase of energy demand and the depletion of land resources, people's attention is gradually shifting from land to sea, and the energy reserves of sea resources are huge, especially the wind energy and wave energy at sea are green and renewable energy. Wind power is currently and even in the future the most scalable and commercial renewable energy. With the development of offshore wind power to the deep sea, the fixed foundation can no longer meet the existing design requirements, and the floating wind power generator system has become a new res...
