(1) power generation system is carried through cable electric weight more than needed to the air compressor 1 of energy-storage system;
(2) air compressor 1 gets electrician's work, and air compressor 1 with in the air pressure indentation high pressure tank 2, increases the air molecule potential energy in the high pressure tank 2 through admission line 4;
In (2) the first water tank 3a water is housed; When needing the startup energy-storage system to generate electricity, the pressurized gas in the high pressure tank 2 are discharged among the first water tank 3a through outlet pipe 5, and the first water tank 3a internal air pressure increases; When air pressure reaches designated value; First makes the interior water of water tank 3a is released into water turbine 10 through outlet conduit 6, and the water in the outlet conduit 6 produce certain kinetic energy under gas pressure, thereby accomplish the conversion of air molecule potential energy to the kinetic energy of water; The power station so has air pressure electric energy more than needed or high pressure tank 2 in can't reach working state the time when starting energy-storing and power-generating system, and air compressor 1 directly injects the first water tank 3a with pressurized gas through second tracheae 14 and outlet pipe 5;
(3) water that has kinetic energy rotates along the impeller 101 that outlet conduit 6 reaches water turbine 10 and promotes water turbine 10, thereby accomplishes the conversion of the kinetic energy of water to mechanical energy; The impeller 101 of water turbine 10 drives the rotor rotation of outer rotor generator 12, makes the generating of bottom generator unit, accomplishes the conversion of mechanical energy to electric energy at last;
(4) water that has kinetic energy enters into the second water tank 3b to water turbine 10 acting backs through water return pipeline 7; After water in the first water tank 3a is all transferred in second water tank, discharge the pressurized gas in the first water tank 3a and the water among the second water tank 3b flow back among the first water tank 3a again;
(5) pressurized gas in the high pressure tank are discharged in the first new water tank through outlet pipe 5 once more, and the above-mentioned steps that so circulates (2) ~ (4) are till having discharged the pressurized gas in the high pressure tank 2.
In sum, when the utility model vertical axis aerogenerator energy-storing and power-generating system generates electricity by way of merging two or more grid systems, its generated output can not impacted to electrical network; Can electric energy be transformed other forms of energy and store, and then convert electric energy into, solve the problem of waste of energy to a certain extent, also break off relations the problem of large-scale vertical wind-driven generator simultaneously from the net generating.
