Floating-type wind energy and wave energy combined power generating system

Abstract

The invention discloses a floating-type wind energy and wave energy combined power generating system which comprises a wind power generating system and a plurality of oscillating water column type wave energy power generating devices of the same structure. As for the wind power generating system, the upper end of a tower tube is connected with a wind power generating unit, a plurality of buoys ofthe same structure are mounted at the lower end of the tower tube through a truss structure to serve as the oscillating water column type wave energy power generating devices, and each buoy is provided with a wave inlet, an air chamber and an air outlet sequentially from bottom to top; an air turbine power generator is mounted at each air outlet; and waves enter the buoys through the wave inlets to drive the air turbine power generators to generate power. The floating-type wind energy and wave energy combined power generating system is simple in structure, convenient to mount and construct, low in cost and wide in applicable water depth range; wind power generating and wave energy power generating are completed on the same supporting structure and shares a supporting platform and a power transmission mating system, and thus the power generating cost is lowered; and the wave energy power generating device adjusts platform damping, thus the motion stability of the system is improved advantageously, and the floating-type wind energy and wave energy combined power generating system is a reliable offshore renewable energy source power generating platform.

Description

technical field [0001] The invention relates to a power generation device, in particular to a floating wind energy-wave energy combined power generation system. Background technique [0002] Wind power is currently the most scalable renewable energy source, and offshore wind power has become a new direction for international wind power development, attracting much attention from all countries. With the gradual saturation of the utilization of onshore wind energy, the proportion of offshore wind energy resources in the entire energy structure is increasing year by year. The development of offshore wind energy is of great significance to my country's environmental protection and energy structure adjustment. Compared with onshore, offshore wind energy resources are more abundant and the quality of wind energy is better, and the research and development of floating wind turbine technology suitable for deep water environment has also attracted more and more attention.

Problems solved by technology

[0003] There are huge wave energy resources in the sea, and the development and utilization of wave energy is also one of the current research hotspots. The wave energy utilization technology is becoming more and more mature, but the conversion rate of wave energy power generation devices is low, and the unit power generation cost is high, which limits its commercial use. application
