Brief description of the drawings
Fig. 1 is the system structure diagram of embodiments of the invention.
Embodiment
In order that those skilled in the art more fully understand the technical scheme in the application, it is real below in conjunction with the application
The accompanying drawing in example is applied, the technical scheme in the embodiment of the present application is clearly and completely described, it is clear that described implementation
Example only some embodiments of the present application, rather than whole embodiments.Based on the embodiment in the application, this area is common
The every other embodiment that technical staff is obtained under the premise of creative work is not made, should all belong to the application protection
Scope.
Referring to Fig. 1, power network transient current control system of the invention, including multigroup intelligent switch 301,302,
303 ... ..., multiple first controllers 201,202,203 ... ... and master controller 100.Wherein, multigroup intelligent switch difference
Corresponding to different home in cell and the electrical equipment of cell public utility.Intelligent switch is capable of unlatching and the pass of control apparatus
Close, and user can be sent to first controller with shutdown signal for switching on.Intelligent switch can set use
Opening and closing information is transmitted in the receiving module for the open command for receiving electric equipment to be opened, and to the first controller
Sending module.Communication mode between intelligent switch and the first controller can be carried out by wireless or wired mode.
First controller 201,202,203 ... ... corresponds respectively to intelligent switch group 301,302,303 ... ....First control
Each switch is corresponding in being stored respectively in device 201,202,203 ... ... processed 201,202,203 in intelligent switch group ... ...
Electrical equipment rated power information, receive each open and close signal.When restarting after power failure, the first controller is received respectively
It is individual to switch on after signal, the rated power sum Pi for the electrical equipment that the family or public utility will be opened is calculated, and
The Pi calculated is sent to master controller 100.
Master controller 100 is the total dsm controller of cell, and it receives all first controller 201,202,203 ... ... hairs
The power information gone out；The information that master controller 100 is transmitted according to all first controllers received, gives each the first control
The different power distribution of device 201,202,203 ... ...；Each first controller 201,202,203 ... ..., according to master controller
The power of 100 distribution, controls the opening sequence of each intelligent switch in its correspondence intelligent switch group 301,302,303 ... ....Always
Controller 100 can be by setting for the different power distribution of each the first controller as follows：a）If all first controls
Device 201,202,203 ... ..., the specified work(for the electrical equipment that its correspondence switches set 301,302,303 ... ... transmitted will be opened
Rate information sum Pi summation sum（Pi）Less than the acceptable total rated power P of the institute of master controller 100, then each is distributed to
The power of first controller is equal to its required power P i；b）If all first controllers 201,202,203 ... ..., institute
The summation sum of the rated power information sum for the electrical equipment that its correspondence switches set 301,302,303 ... ... of transmission will be opened
（Pi）More than the acceptable total rated power P of the institute of master controller 100, then the priority according to corresponding to different first controllers
Carry out power distribution.For cell shared device, the first controller such as elevator, street lamp gives high-grade preference
Limit；And for the electrical equipment of domestic consumer, give the limit priority of inferior grade.For example, the controller of high priority bank first with
And the general power of electrical equipment that low priority group controller will be opened is respectively PH and PL, works as sum（Pi）More than master controller 100
During the acceptable total rated power P of institute, master controller 100 is PH, master controller 100 to the general power that high priority bank is distributed
The general power matched somebody with somebody to low priority component be each first controller is distributed in P-PH, low priority group power for pi ×（P-
PH）/PL.
Pass through the setting of above-mentioned technical proposal, on the one hand, because Cell Site Controller is all distributed for each home controller
Power, electric power distribution is carried out by home controller to intelligent switch, when can avoid the whole cell from controlling together, power load
The problem of small family's sequence can not start rearward；On the other hand, home controller only needs to transmit always appraising and deciding for whole family
Power is to Cell Site Controller, and Cell Site Controller is also that electric power distribution is carried out only in units of family, saves communication and calculates
Resource.
It is preferred that, in above-mentioned technical proposal, multiple LEDs side by side can be set in intelligent switch, if the intelligence is opened
Closing corresponding electrical equipment is needed to open after a certain time, and LED described in the intelligent switching control is lighted successively, wherein rear
The brightness of the LED lighted is higher than the brightness of the LED formerly lighted, and the LED lighted at first and the LED finally lighted
The interval time of lamp corresponds to the special time that the electrical equipment corresponding to the intelligent switch is opened.It is thus possible to prolong in intelligent switch
When starting late, user can be given instruction by the LED of power very little, it is to avoid repeat caused by switching damage to grasp for thinking
Make.
The embodiments of the present invention described above are not intended to limit the scope of the present invention.It is any in the present invention
Spirit and principle within the modifications, equivalent substitutions and improvements made etc., should be included in the claim protection model of the present invention
Within enclosing.
