Abstract
A power grid instantaneous current control system comprises a plurality of groups of intelligent switches, a plurality of first controllers and a main controller. The intelligent switches are capable of controlling the on-off states of electrical appliances and transmitting on-off signals of the switches from a user to the first controllers. Each first controller stores rated power information of the electrical appliance corresponding to each switch in one group of the intelligent switches and receives the on-off signals. The main controller receives information sent from the all the first controllers and gives feedback to the first controllers according to the information. The first controllers control a switching on sequence of the intelligent switches according to the feedback of the main controller. A plurality of parallel LED lamps are arranged by the intelligent switches, if the electrical appliances corresponding to the intelligent switches need to be switched on at special time, the intelligent switches will control the LED lamps to brighten successively.

Accompanying drawing explanation
Fig. 1 is the system structure schematic diagram of embodiments of the invention.
Detailed description of the invention
In order to make those skilled in the art be more fully understood that the technical scheme in the application, below in conjunction with the accompanying drawing in the embodiment of the present application, technical scheme in the embodiment of the present application is clearly and completely described, obviously, described embodiment is only some embodiments of the present application, rather than whole embodiments.Based on the embodiment in the application, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, all should belong to the scope of the application protection.
Referring to Fig. 1, the electrical network transient current control system of the present invention, organize intelligent switch 301 including more, 302,303 ..., multiple first controllers 201,202,203 ... and master controller 100.Wherein, many group intelligent switch correspond respectively to the electrical equipment of different home and community public utility in community.Intelligent switch can control the opening and closing of electrical equipment, and can send user to first controller for switching on shutdown signal.Intelligent switch can be arranged to receive the receiver module of the open command of electric equipment to be opened, and transmit the sending module of opening and closing information to the first controller.Communication mode between intelligent switch and the first controller can be undertaken by wireless or wired mode.
First controller 201,202,203 ... correspond respectively to intelligent switch group 301,302,303 ....First controller 201,202,203 ... in store in intelligent switch group 201,202,203 respectively ... in the rated power information of electrical equipment corresponding to each switch, receive each and open and close signal.When restarting after power failure, the first controller receives after each switches on signal, calculates this family or the rated power sum Pi of electrical equipment that public utility will be opened, and the Pi calculated is sent to master controller 100.
Master controller 100 is the total dsm controller in community, and it receives all first controllers 201,202,203 ... the power information sent；The information that master controller 100 transmits according to all first controllers received, gives each the first controller 201, and 202,203 ... different power distribution；Each first controller 201,202,203 ..., the power according to master controller 100 distribution, control its corresponding intelligent switch group 301,302,303 ... in the opening sequence of each intelligent switch.Master controller 100 can pass through following setting for the power distribution that each the first controller is different: if a) all first controllers 201,202,203, ..., its the corresponding switches set 301,302,303 transmitted, ... the summation sum(Pi of the rated power information sum Pi of the electrical equipment that will open) the total specified power P that can accept less than master controller 100, then distribute to the power of each the first controller equal to its required power P i；If b) all first controllers 201,202,203, ..., its the corresponding switches set 301,302,303 transmitted, ... the summation sum(Pi of the rated power information sum of the electrical equipment that will open) the total specified power P that can accept more than master controller 100, then the priority corresponding to different first controllers carries out power distribution.For community shared device, for instance the first controller of elevator, street lamp etc., give high-grade preferred authority；And for the electrical equipment of domestic consumer, give low-grade limit priority.Such as, general power respectively PH and the PL of the electrical equipment that described high priority bank the first controller and low priority group controller will be opened, as sum(Pi) the total specified power P that can accept more than master controller 100 time, master controller 100 is PH to the general power that high priority bank is distributed, master controller 100 is P-PH to the general power that low priority component is joined, and in low priority group, the power of each first controller distribution is pi × (P-PH)/PL.
By the setting of technique scheme, on the one hand, owing to Cell Site Controller is all assigned with power for each home controller, home controller intelligent switch is carried out electric power distribution, when whole community can be avoided to control together, the problem that family's sequence that power load is little cannot start rearward；On the other hand, what home controller only needed to transmit whole family always appraises and decides power to Cell Site Controller, and Cell Site Controller is also only carry out electric power distribution in units of family, saves communication and calculates resource.
Preferably, in technique scheme, multiple LED side by side can be set at intelligent switch, if the electrical equipment corresponding to this intelligent switch needs to open after a certain time, LED described in described intelligent switching control lights successively, wherein after the brightness of LED that lights higher than the brightness of the LED formerly lighted, and the LED lighted at first and interval time of LED of finally lighting are corresponding to the special time of the electrical equipment unlatching corresponding to this intelligent switch.It is thus possible to when intelligent switch delay start, it is possible to give user instruction by the LED that power is only small, it is to avoid for thinking the repetitive operation that switching damage causes.
Invention described above embodiment, is not intended that limiting the scope of the present invention.Any amendment, equivalent replacement and improvement etc. made within the spirit and principles in the present invention, should be included within the claims of the present invention.
