Multifunctional independent power plant capable of realizing all-weather stable power supply by comprehensively utilizing various kinds of natural energy

Abstract

The invention relates to a multifunctional independent power plant capable of realizing all-weather stable power supply by comprehensively utilizing various kinds of natural energy, aiming to solve the problem of power shortage of sea islands. The multifunctional independent power plant comprises a high-level reservoir constructed at a higher position, and a water turbine generator set connected with the high-level reservoir through a down pipe, wherein a wave power device for converting the fluctuating wave energy into reciprocating or rotating mechanical energy drives a water pump to supply water to the high-level reservoir; or a wind energy power device for converting the wind energy into the rotating mechanical energy drives the water pump to supply water to the high-level reservoir; or a wave power device for converting the fluctuating wave energy of waters around islands, or waters of the mainland coastal area, or inland waters into the reciprocating or rotating mechanical energy is cooperated with the wind energy power device for converting the wind energy into the rotating mechanical energy to drive the water pump to supply water to the high-level reservoir. The multifunctional independent power plant provided by the invention has the advantages of low operation cost and long service, can continuously and stably supply power without being affected by the weather, and can not only supply low-cost natural energy grid power but also co-produce various kinds of island scarce resources, such as fresh water, hydrogen gas, oxygen gas, thereby providing powerful basic resource support for marine protection and development. In addition, the multifunctional independent power plant can also be popularized in other inland surface water source area besides sea islands and mainland coastal area.

Description

technical field [0001] The invention relates to power supply technology, in particular to a multifunctional independent power station which comprehensively utilizes various natural energies to realize stable power supply in all weathers. Background technique [0002] The power supply level of islands is one of the most important factors restricting marine protection and development. At present, there are mainly power supply methods for islands: 1) large islands have their own economical and practical large-scale power plants, and there is no power supply problem; 2) large islands that are close to the mainland or have power plants The islands are connected to the grid power of the mainland or the big island through submarine cables, and there is no power supply problem; 3) Small and medium-sized islands far away from the mainland or the big island use diesel generators for power supply, and the cost of power supply is too high, even making "electricity" a luxury 4) Small and...
