Embodiment
Be described in more detail below in conjunction with the technical scheme of embodiment to this patent.
Refer to Fig. 1-4, a kind of cloud energy storage device, comprise multiple energy storage device monomer 1, the positive pole of described multiple energy storage device monomer 1 is connected by conductor in parallel, the negative pole of multiple energy storage device monomer 1 is connected by conductor in parallel, described energy storage device monomer 1 comprises super energy carrier 2 and frequency converter 3, the positive pole of described super energy carrier 2 connects the P end of frequency changer direct current bus, the negative pole of super energy carrier 2 connects the N end of frequency changer direct current bus, described energy storage device monomer 1 also comprises charging device 4, the positive pole of described charging device 4 connects the positive pole of super energy carrier 2, the negative pole of charging device 4 connects the negative pole of super energy carrier 2, described super energy carrier 2 is super capacitor or superbattery.
If there is N platform elevator in a house, every platform elevator has an energy storage device monomer 1, super energy carrier 2 in energy storage device monomer 1 is attempted by the DC bus of frequency converter 3, if the energy storage device monomer 1 of N platform elevator is respectively A1, A2, A3 ... An, and super energy carrier 2 is wherein attempted by the DC bus of frequency converter 3 of this elevator respectively, again this n energy storage device monomer 1 is together in parallel and realizes resource-sharing, in this N platform elevator, always there are some elevators in electricity consumption, suppose A1, A3, A5 ... An-1 is in electricity consumption; And other elevators are in generating, as A2, A4, A6 ... An is in generating; A1, A2, A3 ... An is together in parallel, the then elevator of generating state, the electric energy sent directly gives the elevator with electricity condition by connecting line, the natural equilibrium obtaining state is unlikely to overflow and waste, and another part electricity consumption elevator stops ladder because the electric energy that obtains power-generating elevator and send supplementary is unlikely to exhausted, like this, no matter be electricity consumption or generating, electric energy in super energy carrier 2 is all fully utilized, reach relative natural equilibrium, also can alleviate the load of energy storage device thus greatly can reduce the deployment cost of super energy carrier 2.
In like manner, total M house in She Yige community, again the energy storage device monomer 1 of the elevator in this M house is connected in parallel again, form a m*n platform energy storage device monomer 1 in parallel, the cloud energy storage device formed, realize larger resource-sharing, power transmission and generating is made to obtain larger natural equilibrium, in like manner, what She Yugai community was adjacent has P community, again the energy storage device monomer 1 of the elevator of this P community and minizone is connected in parallel again, form a larger cloud energy storage aggregate, namely more m*n*p cloud energy storage aggregate is defined as Fig. 4, achieve more resource-sharing, the renewable energy resources are made to have very large energy storing space and power supply space, substantially the natural equilibrium of power transmission and accumulate can be realized, realize maximum energy storage and the energy saving space, reduce energy storage device cost.
A small amount of loss is there is because elevator runs, therefore, the charging device arranging a public high in the clouds beyond the clouds is again for subsequent use, because just the few cases, the probability occurred is less, the utilance of charging device 4 is lower, the charged electrical device that every platform frequency converter 3 inside is arranged can be retained, as according to orthogonal frequency converter, then the elevator in a machine room or a house shares a charging device to carry out a small amount of loss that supplementary elevator runs just enough, the impossible approach infinity of number again due to energy storage device monomer 1 is large, therefore, energy storage device is difficult to the absolute equilibrium guaranteeing power supply and accumulate, need a small amount of retain on existing equipment electric discharge device, can directly be released on resistance, also possibility of reversal returns electrical network, because the probability of electric discharge is also little, so, according to public one of actual conditions machine room Huo Yidong building, even if guarantee that elevator also can normally run under special circumstances.
The present invention averages out when can make elevator or other equipment electricity consumptions or generate electricity, energy storage device capacity is dropped to minimum, thus improve the availability of regenerative electric energy to greatest extent, reduce equipment cost, inversion is exported and reduces to zero, to reduce inversion consumption and inversion to the pollution of environment.
