Description
Technical field
This utility model relates to power distribution automation field, particularly to a kind of Loop Closing Operation controller.
Background technology
Power distribution automation (DA) be one collect computer technology, data transmission, control technology, sophisticated equipment and manage in
The generalized information management system of one, its objective is to improve power supply reliability, improves the quality of power supply, provides a user with high-quality clothes
Business, reduces operating cost, alleviates the labor intensity of operations staff, under Power Market, in order to ensure the confession of terminal use
Electricity reliability, automated system do not require nothing more than can correctly failure judgement, isolate and recover fault, and require increasing to automatically
The investment of change system, increases quickly, switchs reliably and control device, when reducing the frequency of power cut to user and power failure as far as possible
Between.Meanwhile, because of distribution network failure must interrupt unit load power time, should be able to fast automatic identification responsible consumer, preferentially ensure
Its power supply.In order to adapt to the Competitive Needs under market environment, particularly the monitoring to responsible consumer more should accomplish accurately, can
Lean on, sensitive, otherwise bigger loss, this loss can be brought to include directly having a power failure and causing society user to power distribution company
The indirect loss of impact, traditional dual power supply system, the when that interconnection switch closing a floodgate, it is necessary to artificial removes nuclear phase, core
Just can carry out closing operation after errorless, so there is the biggest anthropic factor, the biggest probability causes maloperation.
Summary of the invention
The defect existed based on prior art, this utility model provides a kind of Loop Closing Operation controller, at interconnection switch
The when of combined floodgate, it is not necessary to manually removing nuclear phase, but carried out automatic decision by controller, if meet combined floodgate condition, condition is not
When meeting, controller will not send instruction, so stops maloperation.
To achieve these goals, the technical solution of the utility model is:
A kind of Loop Closing Operation controller, described Loop Closing Operation controller includes an interconnection switch unit, the first voltage
Transformer, the second voltage transformer and a controller unit;Described interconnection switch unit includes an interconnection switch and institute
State the control end of interconnection switch；Described controller unit includes PLC and PC；Described interconnection switch the first end is with described
The input of the first voltage transformer connects, and described interconnection switch the second end connects with the input of described second voltage transformer
Connecing, the outfan of described first voltage transformer connects described PLC first input end, described second voltage transformer
Outfan connects described PLC the second input, and described PLC outfan connects described PC input, described
PLC controls end and the control end of the described PC outfan described interconnection switch unit of connection.
Further, described PLC is also associated with alarm device.
Further, described interconnection switch the first end connects the first power supply through the switch of some series connection, and described contact is opened
Close the second end and also pass through the switch connection second source of some series connection.
The beneficial effects of the utility model are: interconnection switch closes a floodgate when, it is not necessary to manually remove nuclear phase, but by controlling
Device processed carries out automatic decision, and provides prompting, can operate combined floodgate when condition meets, and when condition is unsatisfactory for, controller will not
Send instruction, so stop maloperation.
Accompanying drawing explanation
Fig. 1 is this utility model specific embodiment Loop Closing Operation controller architecture figure.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further described, but embodiment of the present utility model is not limited to
This.
As it is shown in figure 1, Loop Closing Operation controller primary structure, including an interconnection switch unit, this interconnection switch unit
Containing an interconnection switch L, the first voltage transformer, the second voltage transformer, a PLC and a PC, Fig. 1
In, transformer station 1 provides the first power supply, transformer station 2 to provide second source, and the first power supply is through switch L1, L2 of several series connection ...
First end of Ln and interconnection switch L is connected, and second source also passes through switch Ln+1, Ln+2 of several series connection ... Ln+m opens with contact
Closing the second end series connection of L, interconnection switch L the first end end is also connected with the input of the first voltage transformer, the second of interconnection switch L
End is also connected with the input of the second voltage transformer, and the outfan of the first voltage transformer connects PLC first input end,
The outfan of the second voltage transformer connects the second input of PLC, and described PLC outfan connects described PC
Machine input, described PLC controls end and the control end of the described PC outfan described interconnection switch unit of connection.
The high pressure conversion that first power supply and second source are carried by the first voltage transformer and the second voltage transformer respectively
For collected, monitoring, the low pressure that accepts of measurement apparatus (such as PLC) carrying out Real-time Collection detection, PLC is passed through
Real-time Collection to information and calculate in real time, draw the voltage difference of both sides power supply, difference on the frequency, phase contrast, then multilevel iudge,
Draw and currently whether meet cyclization requirement, as met cyclization requirement, then by controlling interconnection switch unit combined floodgate, if do not met
Cyclization requirement, then, when receiving reclosing command, automatically cancel closing operation, thus stopped maloperation.PLC controls simultaneously
Device transfers data to PC, and when alarm device breaks down, PC transfers data to network switching unit, network switching
Unit directly controls closing operation by the control end of interconnection switch unit.
PLC is also associated with alarm device, and when operator mistake occur in operation, PLC is first led to
Program of crossing judges, is then reported to the police by alarm device, reminds operator to correct, and alarm device typically uses sound and light alarm.
Above-described embodiment of the present utility model, is not intended that the restriction to this utility model protection domain.Any in this reality
With amendment, equivalent and improvement etc. done within novel spiritual principles, should be included in right of the present utility model
Within the scope of Yao Qiubaohu.
