Background technique
The world today has two big types for the technology of power storage; Physical method and chemical method; Wherein physical method comprises mechanical energy and the energy storage of electromagnetism field energy; Wherein the mechanical energy energy storage mainly comprises the energy storage of drawing water, compressed-air energy storage or flywheel energy storage, and chemical method comprises with pseudo capacitance, batteries to store energy or hydrogen energy storage.
The energy-accumulating power station that draws water was applied in Italy and Switzerland as far back as the nineties in 19th century, was the fine approach of current extensive solution peak load regulation network.Also be mature and reliable very technically.Its storage capacity can be very big; Only receive the restriction of reservoir capacity; Its shortcoming is the restriction that receives geographical conditions, and two height reservoirs up and down of enough potential energy must be arranged, and in the middle of two processes of drawing water and generate electricity, a considerable amount of energy losses is arranged all; Also have a shortcoming be this power station all away from the electricity consumption load centre, send power transformation also certain energy loss will be arranged.
Compressed-air energy storage proposes the 1950's, has only few countries such as the Germany and the U.S. to use at present.Cry CAES the power station.Here different with the power station of drawing water replaces reservoir exactly with gas holder; The air of environment with the air compressor compression memory in gas holder; Utilize compressed air-driven pneumatic motor or gas-turbine then; Pneumatic motor or gas-turbine drive generator for electricity generation, and the place of " gas holder " of store compressed air is cavern or the waste and old mine that utilizes sealing mostly.
There is the problem of the following aspects in the method for the Caes of now being known:
1) in the storage location choice set, in large scale, invest very greatly, for the pressurized gas encapsulation process certain difficulty is arranged;
2) owing to too concentrated, the certain energy loss is arranged in the power transformation process so send.
Summary of the invention
The utility model provides a kind of pressurized air electric energy energy storage device, with solve in the storage location choice set that Caes exists, in large scale, too concentrate the problem that the certain energy loss is arranged in the power transformation process of sending that makes.
The technological scheme that the utility model is taked is: motor is connected with air compressor, and air compressor is connected with gas holder through pneumatic tube, and this gas holder is connected with pneumatic motor through control valve respectively, and this pneumatic motor is connected with generator.
The described gas holder structure of the utility model is: the outer surface of gas holder attaches polyurethane thermal insulation board, and solar water heater is connected through the circulating water pump heat exchanger inner with being positioned at gas holder, and heat exchanger buffering dividing plate is connected with heat exchanger.
The gas holder of the utility model is placed on underground.
Beneficial effect: the utility model has following some characteristic:
1) the applied equipment of this patent all is standard equipment; Wherein air compressor, motor, pneumatic motor, electric control cubicle all are the standard equipment of technology maturation extensive use; Cost of investment is low, operation technique is simple; Consumable material operating cost is not low so move, and is easy to maintenance, and component interchangeability is strong.
What 2) this patent was used is that the method that breaks the whole up into parts is implemented, and especially can utilize this complete equipment with electric unit, in low power consumption; Lean on clock to start air compressor automatically, compress energy storage is before peak of power consumption arrives; Automatically switch to generating state, electric energy supplement is incorporated into the power networks.
For wind-power electricity generation enterprise; Utilize this patent product to receive the period of wind-powered electricity generation load difficulty at electrical network; The startup energy storage device converts this period wind energy to compressed-air actuated potential energy and stores; By the time the electrical network low ebb converts electric energy later again to and is discharged into the electrical network use, reduce wind-powered electricity generation and abandon wind, improve the wind power equipment utilization ratio.
3) solved low power consumption period waste of electric energy, its economic benefit is fairly obvious.
4) can disperse to set up network of composition to set up jointly in the more area of low power consumption; Avoid maximizing; Can avoid investing excessive like this; Form the huge storage networking of a very big storage of electrical energy gradually, another advantage of doing like this is the part maintenance of breaking down, and can not influence the normal operation of whole system.
Characteristics according to this patent; The purposes of this patent consists essentially of: the first can be utilized the unit of this patent a shortage of electric power; The equipment of assembling one cover this patent starts compress energy storage at the electrical network low-valley interval, and the electric network peak period starts and begins generating; Utilize the electric energy of low ebb electricity price period to supply the spike period to use the economic benefit of under time-of-use tariffs difference, trying to achieve; It two is air compression energy storage devices that certain scale is installed in wind-power electricity generation enterprise; In plentiful season of wind-force and period, the wind-powered electricity generation capabilities limits because electrical network is dissolved is influenced by heat supply for example; Receiving wind-powered electricity generation to account for electric load ratio height influences; Convert wind energy to pressurized air and store, discharge again during conditions being possessed, can improve the utilization ratio of wind-power electricity generation clean energy resource; It three is after forming scale this patent product around the wind power station; With thoroughly changing the generator operation characteristic of wind power plant in electrical network; By original moving with the wind; Become electric load and can adjust moving with need of control at any time, grid dispatching center is become initiatively by passive the control of wind-powered electricity generation load; Aspire for stability and become the stability and high efficiency economic operation model to abandon wind; If this method is applied, the effect that will play wind-powered electricity generation developing history turning point to the safety and stability that relates to wind-powered electricity generation net system and economical operation.
