Description

technical field [0001] The invention relates to the technical fields of hydroelectric power generation and wind power generation, in particular to a method for comprehensively utilizing ocean energy and wind energy for centralized compressed air power generation and a device for comprehensively utilizing ocean energy and wind energy for centralized compressed air power generation. Background technique [0002] As we all know, hydropower or wind power is an environmentally friendly power generation technology that converts the kinetic energy of water or wind into electrical energy through the kinetic energy input of the hydroelectric generator or wind generator. Both of them belong to the reasonable development and utilization of natural environmental protection energy by human beings. It will not consume non-renewable energy fuels like thermal power generation, release a large amount of harmful gases and heat that pollute the atmospheric environment, and will not have nuclear...

Problems solved by technology

But at present, whether it is a wave power station, a sea tide power station or an ocean wind power station, only one of the resources is used, while the other resource is not fully utilized. Either the incomplete capture of wave energy and tidal energy results in a low conversion rate of energy utilization; or the equipment is scattered and installed in the sea, which is not only inconvenient for equipment maintenance and centralized management, but is easily corroded by seawater, and the equipment life is short; The instability of the sea waves leads to the instability of power generation, causing the installed generators to fail to generate electricity when the waves are small, and the generators will be burned out when the waves are large, and the generated electricity cannot be directly integrated into the existing power grid due to factors such as lack of stability. In addition, it is aimed at the singleness of energy utilization, which increases the investment cost and operation cost of power generation, and is not convenient for building large or super large power stations.

Moreover, the current cost of wind power generation is very high, especially the cost of building a single large-scale wind power generator will increase exponentially. Building a single wind power station in the ocean is not only costly, but also inconvenient for centralized management and operation
