The utility model is applied to a kind of a kind of looped network intelligent control method such as Fig. 4-5 institutes of looped network intelligence control system
Show, comprise the following steps：
S1, digital display meter 73 obtains corresponding calling loop 31 and its electrical parameter data of the low-pressure side of corresponding transformer 1 is sent
To control centre 5；
S2, the embedded computer 51 of control centre 5 is to all calling loops 31 and the electrical parameter number of the low-pressure side of transformer 1
According to being analyzed, 1 respective status of transformer is judged, the state includes power failure state, mistake, heavy condition, normal condition
With idle condition, it is in power failure state in a certain transformer 1 of judgement or crosses, heavy condition, while another transformer 1 be present and be in
During idle condition, proceed by loop and turn to supply；
S21, embedded computer are monitored to all low-voltage bus bar voltage datas, if finding a certain low-voltage bus bar voltage
When data are less than dead electricity setting value, then judge that corresponding transformer 1 is in power failure state, stop to crossing, the judgement of heavy condition, hold
Row step S24, conversely, performing step S22；
S22, embedded computer 51 are ranked up on earth to low-voltage bus bar current data by height；
S23, highest low-voltage bus bar current data is compared, judges correspond to whether transformer 1 exceeded, heavy duty is set
Definite value, if exceeding, judging that correspondingly transformer 1 was in, heavy condition if heavily loaded setting value, on the contrary then determination circuit is in just
Normal state, end operation；
S24, when judging that transformer 1 is in power failure state or mistake, heavy condition, embedded computer 51 is to load current
Data are ranked up as low to high；
S25, minimum load current data is compared, judges whether corresponding transformer 1 is less than idle setting value, if
Less than idle setting value, then judge that corresponding transformer 1 is in idle condition, perform step S3, conversely, then judging corresponding transformer
1 can not meet that loop turns the requirement supplied, stop operation startup alarm module 53 and alarmed.
S3, embedded computer 51 is by power failure state or mistake, the corresponding calling loop of the transformer 1 of heavy condition
31 switching mechanism 7 disconnects, by with power failure state or cross, corresponding the calling loop 31 of the transformer 1 of heavy condition is connected
The switching mechanism 7 in the contact loop 62 connect closes, while loop 31 and connection will be called corresponding to the transformer 1 in idle condition
Switching mechanism 7 on network loop 62 closes, and realizes that loop turns to supply；
S4, embedded computer 51 are monitored to the electrical parameter data of transformer 1, when the transformer for turning to supply in loop
When 1 electrical parameter data is less than idle setting value, corresponding switching mechanism 7 is reset, loop is released and turns to supply.
Above method step integrally realizes a kind of overall operation of looped network intelligence control system, is judging whether to need to turn
, it is necessary to set dead electricity setting value in advance for during, cross, heavily loaded setting value and idle setting value, cross, heavily loaded setting value bag
Overload setting value and heavily loaded setting value are included, heavily loaded setting value is no more than the load current value of transformer 1, generally sets heavy duty
Value is set under the specified current flow value of transformer 1, and by the data setting of 0.7-0.9 times of specified current flow value, overload setting value is
The specified current flow of transformer 1, during general estimation, mainly using heavily loaded setting value, the general heavily loaded duration is long, directly enters
Row loop turns to supply, if data exceed overload setting value, the quick loop that carries out turns to supply, the best condition of idle setting value be for 0,
In zero load i.e. in the loop, but under actual conditions, the situation can not possibly be present, and therefore, idle setting value is generally according to transformation
0.05-0.15 times of the specified current flow value of device 1 is set, and ensures to pass through by the calling loop 31 in the transformer 1 of heavy duty
When contact loop 62 is linked into the transformer 1 of free time, the transformer 1 of free time will not be caused to bear, dead electricity setting value is 0, one
As dead electricity situation occur if, i.e., transformer 1 is distress condition, and low-pressure side voltage should be 0.The setting got in touch with loop 62 is opened
Shutting mechanism 7 is acquired to the contact loop 62 and the voltage in the low-pressure side of transformer 1 with electric current, and electrical parameter data is also sent
To control centre 5, embedded computer 51 is finding contact loop 62 with the electrical parameter data of the low-pressure side of transformer 1 less than the free time
When setting value, it is considered that its corresponding transformer 1 there will be no, heavy condition, therefore cancel specializing in for loop, i.e.,
Switch reconfiguration will be corresponded to, the called calling loop 31 of original is gone back into original loop, has script transformer 1 to be powered, it is excellent
Choosing, the transformer 1 is 630kAV transformers, its load current value In=909A, formulates current value Ir=727A.
In the above, when judging dead electricity, overload, heavy condition, be also set with dead electricity delay T1, overload delay T2,
Heavy duty delay T3, when determination circuit is in abnormal condition, the delay of certain time can be passed through and judged again, it is ensured that dead electricity,
Overload, heavy condition are effective, and the dead electricity delay is 0 ~ 10 second, and overload delay is 0 ~ 10 second, and heavy duty delay is 1200 ~ 3600
Second.
A kind of looped network intelligence control system and its control method of the present utility model realize the transformation to power distribution network, reduce
The overload possibility of transformer 1, while the interim solution supplied during dead electricity loop turn is also provided, the program solves change
Depressor 1 can avoid the mode using power failure of avoiding the peak hour because overload causes the situation of burning transformer 1, and then solve frequently to stop
The problem of electricity.
Above content is to combine the further description that specific preferred embodiment is done to the utility model, it is impossible to
Assert that specific implementation of the present utility model is confined to these explanations.For the ordinary skill of the utility model art
For personnel, without departing from the concept of the premise utility, some simple deduction or replace can also be made, should all be regarded
To belong to the scope of protection of the utility model.
