Method, the method step are as follows: one, the input by substation, outlet side and stand electricity consumption power carry out real-time monitoring, and
The power for calculating each transformer consumption in real time, judges between transformer with the presence of aspergillus ficuum；If two, had between transformer
Circulation exists, and the parameter of transformation is measured by test method, then adjusts the gear of transformer, so that its impedance parameter is consistent,
Circulation can be eliminated, and then avoids electric energy loss caused by circulation.
In the step 2, test method are as follows: when judging transformer there are when circulation, in conjunction with transformation by monitoring data
The power failure of device is tested, and after isallobaric device has a power failure, measures two transformers respectively using instrument for measuring DC resistance in each gear
Under DC resistance make the direct current of two transformers according to measurement as a result, the gear of transformer is readjusted
Resistance value is equal or closest.Since the impedance value of two transformers after readjustment gear is equal, so change can be eliminated
Existing circulation between depressor, to achieve the purpose that decreasing loss.
As shown in Fig. 1, in the process of running, there is following equation establishment in substation:
P1=P2+P3+P4+PDamage (1)
Wherein: P1For the received power of substation, P2For the power for pressing outlet side in substation, P3It is defeated for substation's low pressure
The power of side out, P4For the power of substation's interior electric consumption in station, PDamageTo consume the power on substation transformer, the loss
Consist of two parts:
PDamage=PInterior damage+PCirculation (2)
Wherein: PInterior damageTo consume the loss on each transformer when transformer station high-voltage side bus, it is divided into no-load loss and load loss two
A part.Wherein no-load loss is mainly core loss, which is held essentially constant, and can directly be known by transformer nameplate；
Load loss changes with the variation of load, square directly proportional to load current；PCirculationBetween the transformer of paired running
The power consumed due to there are circulation, the reason of causing circulation are that impedance is unequal between transformer.
Therefore, real-time monitoring is carried out by the active power of input to substation, outlet side and electricity consumption of standing, and in real time
The power for calculating each transformer consumption, can judge between transformer with the presence of aspergillus ficuum.Under normal circumstances input with it is defeated
The relationship of active power out are as follows:
P1=P2+P3+P4+PInterior damage (3)
