Description

A kind of wind-power pumping water generating system
Technical field
The present invention relates to a kind of wind power utilization field, particularly water pumping of the wind-force and hydroelectric power.
Background technique
Mainly take the mode of wind turbine power generation at present for the utilization of wind energy, also have to be used to the water pumping of the wind-force mode of irrigating and drinking water on a small quantity.
Wind turbine power generation is the rotation that wind energy drives blower fan, drives generator for electricity generation.Because the uncertainty of wind energy size is very big, so the motion speed of blower fan is very unstable, generator sends aspect such as the voltage, waveform, frequency of electric energy and all is difficult to reach the requirement of being incorporated into the power networks.Usually adopt rectification circuit that it is carried out rectification, could import electrical network after reaching the requirement of being incorporated into the power networks.The device that carries out rectification for the electric energy of generator output not only costs an arm and a leg, and rate of fault is also high, and these make that all the more traditional electricity-generating method of the cost of wind-power electricity generation is high a lot.There are some higher harmonicss in addition in the current waveform behind over commutation, electrical network is polluted.And the electric energy size of wind-driven generator output is indefinite, can not guarantee stably to export electric energy, for the stable operation meeting generation adverse influence of electrical network.
It only is a very little part to Wind Power Utilization that the water pumping of the wind-force mode that is used at present to irrigate and drinks water is utilized wind energy, can not abundant wind resource be made full use of.
Through for many years accumulation, very ripe technically, the efficient of Conversion of energy is very high in the hydroelectric power for hydraulic power generation technology.
The principle of water pumping of the wind-force generating is mentioned in patent 01135136.5 " wind power and hydraulic power combining power generating method and device " and patent 200610026128.0 " a kind of method of combined generation of wind power and hydropower ", that is: utilize water pumping of the wind-force equipment that water is risen to eminence from lower, make water flow to lower through hydroelectric installation then, promote the hydroelectric installation generating from eminence.
Among the embodiment 1 of patent 01135136.5 " wind power and hydraulic power combining power generating method and device ", be electric energy with wind energy transformation at first by wind-driven generator, utilizing electric energy to drive electric pump again draws water, still need complicated rectifying installation that the electric energy of wind-driven generator output is converted into the needed electric energy of electric pump in this process, input expense height, and the quality of power supply is poor.In embodiment 2, waterwheel of a wind wheel band or water elevator are suitable for power station, small-sized geomantic omen engineering, and be low for large-scale blower fan utilization ratio.
Patent 200610026128.0 " a kind of method of combined generation of wind power and hydropower " is described to rise to eminence with water from lower by water pumping of the wind-force equipment, for large-scale blower fan apart from tens of rice in ground even rice up to a hundred, this will lose blower fan and high-order this part potential energy of water surface difference, and this will make the transformation efficiency of wind energy reduce greatly.
Summary of the invention
The objective of the invention is to overcome the shortcoming of prior art, propose a kind of wind-power pumping water generating system efficiently.The present invention can improve the utilization ratio of wind energy, invests for a short time, and cost is low, and is the high-quality electric energy of electrical network output.
The present invention is the potential energy of water at first fully with wind energy transformation, by hydraulic turbine generator the potential energy of water is converted into electric energy again.In order to improve the utilization ratio of wind energy, the mode that the present invention adopts the two poles of the earth to draw water realizes, that is: the water that flows out from the water pump of blower fan height does not directly inject elevated reservoir, extracts more water in elevated reservoir but through a water turbine potential energy of this part water is used in again.
The present invention mainly comprises elevated reservoir, low level reservoir, blower fan, water pump, water turbine, hydraulic turbine generator and pipeline.A high position and low level reservoir, and blower fan, water pump, water turbine and hydraulic turbine generator are arranged in different level heights.The low level reservoir is positioned at lowest part, and elevated reservoir is higher than the low level reservoir, water turbine and hydraulic turbine generator on the vertical height between elevated reservoir and low level reservoir, and this water turbine links to each other with hydraulic turbine generator is coaxial.An one typhoon machine and coaxial linking to each other of water pump, its position is higher than elevated reservoir.Another water turbine links to each other with another water pump is coaxial, between the water pump and elevated reservoir that link to each other with blower fan.
Working procedure of the present invention is as follows: blower fan rotates under the driving of wind-force, drives pump working, and water pump is extracted into the water in the low level reservoir in the water pump, and the mechanical energy that in this process blower fan is obtained from wind is converted into the potential energy and the kinetic energy of water.The water that flows out from water pump enters water turbine through pipeline, drive the rotation of water turbine, the water that flows out from water turbine is injected into the elevated reservoir, and the rotation by water turbine simultaneously drives another pump working, and this water pump directly is extracted into the water in the low level reservoir in the elevated reservoir.Retaining in the elevated reservoir flows to the low level reservoir through a water turbine, and this water turbine drives the hydraulic turbine generator generating.
Blower fan is installed on the frame according to the corresponding geographical position, apart from the tens of rice in ground rice extremely up to a hundred, blower fan drives water pump water is extracted into the blower fan height for large-scale blower fan, and the glassware for drinking water of this moment has very big potential energy, if the water that water pump is flowed out directly is discharged to elevated reservoir, will lose this part potential energy.Therefore for the efficient of Conversion of energy in can the raising system, be provided with a water turbine at the elevated reservoir place and utilize this part potential energy.Rotation by this water turbine drives the water pump rotation, directly the water in the low level reservoir is extracted in the elevated reservoir.
Water pump selected in this system all should have the characteristics of big water quantity, low water head, and the potential energy that can make full use of water like this transforms, the energy loss in the reduction process, the total efficiency of raising system.
Actual conditions according to wind field design separate unit or many typhoons machine near reservoir, separate between each blower fan.
