Description
Technical field
This utility model is related to low-voltage distribution network wireline inspection technical field and in particular to a kind of low-voltage platform area physical topology exists
Line generates and real-time monitoring system.
Background technology
In recent years, with the fast development of electrical network, the hardware facility of distribute-electricity transformer district has obtained great perfect.And power train
The marketization of system, proposes, to management of power use department, the management more becoming more meticulous and requires.The demand of consumption reduction detraction is more urgent, reduces
Platform area line loss per unit, Shi Tai area line loss per unit meets national standard and has become an important index.And in Controlling line loss, Fen Tai area,
Split-phase management is the most difficult, is mainly reflected in:
1st, platform area basic data is not complete；For some old areas, because the time is longer, the originally data loss of preservation,
Or after later stage track remodelling, fail the basic data that upgrades in time, cause data and the unmatched result of actual track.
2nd, user privately overlaps and uses electric line, and especially in platform area intersection it is easier to cause crossover phenomenon, this kind of situation adds
Chong Liaotai area circuit confusion degree.
At present, commonly used station user identification apparatus are carrying out the identification of platform area.Platform area identifier has two types at present:
1st, traditional, adopt power line carrier, PLC mode merely, it passes through to produce an electric power in distribution low-voltage side and carries
Ripple signal source, detects this power carrier signal in tested place, if this signal can be detected it is possible to judge that measured point belongs to this
Distribute-electricity transformer district.
2nd, the knowledge of platform area is carried out using the two-way confirmation method again that pulse characteristicses current signal and power carrier signal combine
Not.The method is to send a pulse characteristicses current signal in measured point to power circuit, is arranged on the main frame of distribution low-voltage side
After this pulse characteristicses current signal is detected, then carry out validation of information with measured point device by way of power line carrier, PLC,
Thus judging that measured point belongs to a certain phase of this distribute-electricity transformer district.
Simple have two distinct disadvantage by the way of power line carrier, PLC: adjacent stations become altogether high pressure, altogether, common-battery cable
Because getting lines crossed of carrier signal easily causing erroneous judgement in the case of ditch；Power carrier signal is high-frequency signal, and decay is serious, away from
From the big user's None- identified of length, line-hit；The method being combined using pulse characteristicses current signal and power carrier signal
Although improve the reliability of identification, complex operation, workload is big.
Above two station user identification apparatus broadly fall into on-the-spot test instrument, are a kind of off-line test methods.On-the-spot test
When, need the belonging relation of staff's manual test measured point and the distribution transforming of platform area, for the distribute-electricity transformer district of complex circuit, determine
During lines branch relation, Field Force's workload is big, takes considerable time, and can not automatically generate line connecting relation, needs
Manual sorting.The method of testing of this off-line type, also cannot realize the real-time monitoring to platform area topology.
