Description
Technical field
The utility model belongs to power station area technical field of measurement and test, is specifically related to a kind of area user identification zone device of multimode manner.
Background technology
Along with the continuous propelling of national intelligent power network work, to electrical network, intelligent and fine-grained management requires more and more higher, but the management of refinement first will based on basic data comprehensively and accurately.Use now the platform district identifier of carrier wave principle as the indispensable instrument of platform district fine-grained management on the market, serve very important effect.But based on the inherent characteristic of FSK carrier communication principle, its deficiency also shows day by day, be mainly manifested in following two broad aspect:
The uncertain problem of 1 decipherment distance: the Different periods for same circuit can receive carrier signal sometimes, sometimes but cannot receive, its main cause is that the Different periods user of low voltage electric network is different to the intensity of the noise that electrical network produces, the line impedance that Different periods user load difference causes is different, thus cause the deep fades of carrier signal, long-distance transmissions that cannot be stable, makes the platform district identifier based on carrier communication principle reliable and stablely to identify.
2 identify accuracy problem: for platform district transformer altogether high pressure, altogether, the platform district of the adjacent multiple stage distribution transforming of cable trough altogether identifies the problem that there is accuracy, because the platform district identifier of carrier wave principle only adopts FSK power carrier signal to carry out user's identification, and carrier signal is high-frequency signal can be coupled to 10kV high-pressure side by distribution transformer, adjacent distribution transforming is transferred to again by 10kV high-voltage line, FSK technology cannot distinguish the same phase of this distribution transforming and adjacent distribution transforming, thus cause " getting lines crossed " phenomenon, both " high pressure is being got lines crossed altogether "; If in like manner adjacent distribution transforming has common ground situation, carrier signal equally also can got lines crossed to adjacent distribution transforming, namely " gets lines crossed altogether "; If the low-voltage cable of adjacent distribution transforming walks same cable ditch, carrier signal can be gone here and there in other distribution transforming by the capacitive coupling between cable, both " cable trough is being got lines crossed altogether ".
Utility model content
