Wind/wave hybrid power generating system

Abstract

The invention belongs to the field of novel energy power generation, and in particular relates to a wind / wave hybrid power generating system. The wind / wave hybrid power generating system consists of a wind energy catching device, a first hydraulic pump connected with the wind energy catching device for outputting hydraulic energy, a wave energy catching device, a hydraulic cylinder connected with the wave energy catching device, a generator, a hydraulic motor and a first energy accumulator, wherein the input port of the hydraulic motor is respectively connected with a first check valve and a second check valve, and the first energy accumulator is connected with the input port of the hydraulic motor through a first throttling valve, a first pressure matching device is further arranged between the first hydraulic pump and the first check valve, and a second pressure matching device is further arranged between the hydraulic cylinder and the second check valve. When the two hydraulic oil liquid paths input by the two sets of energy catching devices are combined into one path to be outputted, the confluence input pressure grades of the two hydraulic oil liquid paths can be matched by means of the two pressure matching devices, or when the confluence input pressure degrees of the two paths are not matched, the situation that one of the energy catching devices is stopped due to that one input blocks the other input is smooth can not occur.

Description

technical field [0001] The invention belongs to the field of new energy power generation, and in particular relates to a wind-wave complementary power generation system. Background technique [0002] More than two-thirds of the earth's surface is covered by oceans, which contain abundant renewable energy. Ocean energy in a broad sense includes offshore wind energy, ocean current energy, wave energy, and solar energy. In order to reasonably protect natural resources and alleviate the contradiction between energy supply and demand, it is still very important to adopt a method of complementing each other with multiple energy sources. [0003] In the process of developing ocean energy, two or more types of ocean energy can be developed and utilized at the same time, so that multiple energy sources can complement each other and improve the utilization rate of ocean energy. [0004] Scotland's Green Ocean Energy Company has developed a wave energy generator Wave Treader, which ca...

Problems solved by technology

[0006] The technical problem to be solved by the present invention is to provide a wind and wave complementary power generation system. When the two hydraulic fluids output by the wind energy harvesting device and the wave energy harvesting device of the system merge into one output, if the pressure of the two hydraulic pressures combined If the levels are the same (that is, the pressure levels match), the hydraulic confluence will go smoothly; if the pressure levels of the two hydraulic confluence inputs are not the same (that is, the pressure levels do not match), only the hydraulic confluence input with a higher pressure level will continue to flow in, and the other hydraulic confluence will continue to flow in. The confluence input is not confluent, but flows into the accumulator for energy storage, so that one set of energy harvesting devices will not stop running due to one hydraulic confluence input blocking the other hydraulic confluence input
