Description
Technical field
The present invention relates to the flywheel energy storage technology in a kind of power storage technology, is a kind of magnetically levitated flywheel energy storage device that adopts the integrated flywheel of suspension/energy storage specifically.
Background technology
The storage of electric energy can be divided into electrochemical energy storage, electromagnetism energy storage, phase-change accumulation energy and physics energy storage four major types according to concrete mode.Wherein electrochemical energy storage comprises lead-acid battery energy storage, Ni-MH battery energy storage, nickel-cadmium cell energy storage, lithium ion battery energy storage, sodium-sulphur battery energy storage and flow battery energy storage, the electromagnetism energy storage comprises superconducting energy storage and super capacitor energy-storage, phase-change accumulation energy comprises ice cold-storage energy storage etc., and the physics energy storage comprises the energy storage of drawing water, compressed-air energy storage and flywheel energy storage.
Electrochemical energy storage device is to refer to by electrochemical reaction, and chemical energy anodal, negative electrode active material is converted into a class device of electric energy.Electrochemical energy storage device is cheap, technology maturation, but seriously polluted, efficient is low, and the life-span is short, and electric energy is wayward in the use.
Superconducting energy storage in the electromagnetism energy storage is converted into magnetic energy to electric energy and is stored in the magnetic field of superconducting coil, because the resistance of superconducting coil is zero, therefore superconducting energy storage efficient is than higher, pollution to environment is also smaller, but compare with other energy storage modes, the price comparison costliness of superconductor itself, the energy of keeping low temperature simultaneously and being consumed is also considerable with the expense that needs.Super capacitor is meant that storage volume is the electric capacity of 20～1000 times of ordinary capacitor.It is by using a kind of porous electrolyte to strengthen the area of two-plate, thereby energy storage capacity is improved, super capacitor has advantages such as energy density is big, the speed that discharges and recharges is fast, the life-span is long, its shortcoming is if the improper use meeting causes phenomenons such as electrolyte leakage, compare with alminium electrolytic condenser simultaneously, its internal resistance is bigger, cannot be used for alternating current circuit.
Phase-change accumulation energy is to utilize phase-change material in phase transition process the form of heat with latent heat to be stored in self or to discharge the performance of giving environment, electric energy is changed into thermal energy storage, so bigger shortcoming of phase-change accumulation energy is exactly that transformation efficiency is lower.
Generating is opened a sluice gate in the reservoir energy storage of drawing water upstream of electric power when the energy storage of drawing water in the physics energy storage utilizes electrical network rich downstream during power tense, the release time of the energy storage of drawing water can be from several hrs by several days, and overall efficiency is between 70%～85%.Compressed-air energy storage is meant under high-pressure situations stores a large amount of regenerative resources by compressed air, it is stored in large underground hole, depleted well or the aquifer then, during discharge, the air of compression just is released, and generate electricity by promoting turbine, one can store the energy of hundreds of hour, and the shortcoming of compressed-air energy storage is that energy density is low, and is compressed the restriction of air storage condition.The principle of flywheel energy storage is exactly to quicken rotation by driven by motor flywheel disk, makes electric energy change into the rotation function of flywheel, and when outwards powering, machine operation is at the generator state, and accumulated energy flywheel drives the generator amature rotation mechanical energy is converted into electric energy.
Comprehensively above-mentioned, than other energy storage modes, the main advantage of flywheel energy storage shows: (1) energy storage density height, and instantaneous power is big; (2) charging interval is shorter; (3) long service life; (4) energy conversion efficiency height, one can reach 85～95%; (5), very friendly to environment to temperature-insensitive.Therefore, the flywheel energy storage technology is considered to be hopeful most at present, the most competitive energy storage technology, has boundless application prospect.
In order to reduce mechanical friction, one adopts magnetic suspension bearing that rotor is suspended in energy accumulation device for fly wheel.Whether controlled according to suspending power, magnetic suspension bearing can be divided into passive-type and active two types.The passive-type magnetic suspension bearing mainly utilizes repulsion intrinsic between the magnetic material or suction (between permanent magnetic material, between permanent magnetic material and the soft magnetic material) to realize the suspension of rotating shaft, and it is simple in structure, and power loss is few.Active magnetic suspension bearing mainly is a stable suspersion of realizing rotating shaft by the magnetic field force between the ACTIVE CONTROL stator and rotor, the complete active magnetic levitation bearing system of one cover is made up of magnetic suspension bearing body, displacement transducer, controller and power amplifier usually, set up the difference of mode according to bias magnetic field, active magnetic suspension bearing can be divided into full electromagnetic type and electromagnet and permanent magnet mixed type.The bias magnetic field and the controlling magnetic field of full electromagnetic type magnetic suspension bearing produce by electromagnet; Electromagnet and permanent magnet hybrid magnetic suspension bearing adopts permanent magnetic material to set up bias magnetic field, can reduce the power loss of magnetic suspension bearing largely.
