Abstract

The power generating equipment consists of lower position reservoir, upper position reservoir, wind driven water pump system and hydraulic power generating system. The method of combining wind driven water pump system to pump from the lower position reservoir to the upper position reservoir and the hydraulic power generating system to generate electricity with water in the upper position reservoir makes it possible to output continuous and smooth electric energy and to utilize wind energy in large scale.

Description

Wind power and hydraulic power combining power generating method and device

Technical field:

The present invention relates to the electricity wind-power electricity generation, particularly a kind of power generating method and device that utilizes water pumping of the wind-force to combine with hydroelectric power.

Background technique:

At present, the wind power station of various places and hydroelectric power plant independent operating separately.Like this, hydroelectric power plant can only be built existing current in, and the big place of water drop.Resemble the island, inexhaustible seawater is arranged, but do not have big drop height water stream just can't build the water power plant.And the wind power station of isolated operation, wind-force reception switching mechanism directly drives generator for electricity generation and output after putting in order, because the wind-force size is indefinite, cut in and out, electric energy frequency of being exported and size are indefinite, and the steady electric power of the output of macro-energy has influenced the networking of wind-powered electricity generation continuously.Measure through the relevant expert, wind-powered electricity generation networking amount can not surpass 10% of whole electrical network installation total amount, otherwise just influence the smooth running of whole electrical network, thereby become the bottleneck that restriction large-scale develops and utilizes wind energy, as maximum wind-powered electricity generation factory---Xinjiang Da Bancheng wind-power electricity generation two factories of China, gross generation is 5.75 ten thousand KW.In order to address this problem, prior art adopts that rectification, storage battery store, the method for inversion more, resembles Chinese patent application and number be 00120550.1 patented technology " a kind of transformation device that send that improves the wind-power electricity generation capacity usage ratio ".Because the storage battery energy stored is little, the current harmonics component after the inversion of cost height, and process relatively is big, easily whole electrical network is caused harmful effect.The Ming Tombs, Beijing retaining power plant, it is with the electric power electric power storage of drawing water, and has just played electricity consumption paddy peak regulating action, this and wind-power electricity generation are irrelevant.

Summary of the invention:

The objective of the invention is to provide a kind of and can large-scale develop and utilize wind energy, export power generating method and the device that electric energy is not subjected to the restriction of networking amount continuously stably.It combines water pumping of the wind-force and hydroelectric power, utilize the water pumping of the wind-force system, water in the low level reservoir carried in elevated reservoir store, wind energy is stored in the elevated reservoir so that the form of potential energy is jumbo, the hydroelectric power system utilization is stored in the water generating in the elevated reservoir, with this potential energy converting and energy is electric energy, thereby finishes the conversion of whole energy, make cut in and out, the time when big little wind energy be converted to continuously electric energy stably.Utilize the water of elevated reservoir to store wind energy, capacity is big, is convenient to implement, water pumping of the wind-force and hydroelectric power are organically combined, wind energy utilization is improved, output power frequency and size keep stable, the quantitative limitation that do not networked, and can bring into play resources superiority fully.Resemble the littoral area of rivers,lakes and seas, though there is not the high drop height water stream of nature, the wind that had mountain and water just can be built the power station, geomantic omen, particularly the wind resource in island and mountain area, hills is large-scale developed and utilized technical support is provided, deserted mountain, many islands just can become energy base.

Embodiment:

Wind power and hydraulic power combining power generating method of the present invention and device, it is made up of water pumping of the wind-force system, hydroelectric power system, low level reservoir, elevated reservoir.Wherein, wind-force receives conversion portion and is made of water pumping of the wind-force system, low level reservoir, elevated reservoir, and power generation part is made of hydroelectric power system.The water pumping of the wind-force system comprises wind-force receiving mechanism and water elevator, and the wind-force receiving mechanism offers water elevator with the energy that receives, and water elevator is carried the water in the low level reservoir in elevated reservoir.According to natural environmental condition, low level reservoir and elevated reservoir various informative both can be rivers,lakes and seas, arm pond, also can be artificial reservior, well pond, or the water tank water tower.Hydroelectric power system is made up of water transport channel, hydroelectric generator and electric power output control network, utilizes the water in the elevated reservoir to generate electricity by the water transport channel hydroelectric generator, through electric power output control network output electric energy.

The invention will be further described below in conjunction with embodiment.

Embodiment 1

The wind power and hydraulic power combining power generating method and the device that comprise water pumping of the wind-force system, hydroelectric power system, low level reservoir, elevated reservoir, wind-force receiving mechanism in the water pumping of the wind-force system is made up of wind-driven generator and automatic control distribution network, what water elevator was used is electric pump, wind-driven generator is an electric energy with wind energy transformation, through controlling distribution network automatically, give electric pump with electric energy, electric pump rises to the water in the low level reservoir in the elevated reservoir.Wind-driven generator can be a separate unit, also can many generates electricity by way of merging two or more grid systems.According to the wind field resource situation, electric pump adopts many multichannel controls, be that many electric pumps divide many passages that water is taken out to elevated reservoir from the low level reservoir, the electric pump of each bar passage just is one tunnel load, when wind-force hour, only be with one tunnel load, when wind-force strengthens gradually, automatically the control distribution network just increases the way of energising gradually according to the result of test, when wind-force weakens gradually, controls just gradually unloading of distribution network automatically.No matter wind-force has much variations, the wind-power electricity generation function is in the state of operating at full capacity all the time like this, and to maximally utilise wind energy, it is particularly suitable for power station, big-and-middle-sized geomantic omen engineering.

Embodiment 2

Comprise the wind power and hydraulic power combining power generating method and the power station, geomantic omen of water pumping of the wind-force system, hydroelectric power system, low level reservoir, elevated reservoir, wherein, the water pumping of the wind-force system directly is made up of wind wheel, waterwheel or water elevator.Wind wheel is gathered wind-force, directly drives waterwheel or water elevator water is carried toward elevated reservoir from the low level reservoir, finishes the conversion of wind energy to potential energy.For wind wheel, waterwheel or water elevator, this belongs to one and is with a form, both waterwheel of a wind wheel band or water elevator, and this is suitable for power station, small-sized geomantic omen engineering.
