Description
Technical field
The present invention relates to the technical field of power line carrier communication more particularly to a kind of bandwidth carrier taiwan area recognition methods.
Background technology
In the power system, taiwan area refers to the supply district or region of (one) transformer.Power consumption management department is consumption reduction
Detraction, needs to investigate thoroughly the taiwan area of user and separate attribute using station user identification apparatus, to realize that taiwan area fine-grained management provides
Really and accurately basic data.
The corporate external having at present declares have taiwan area identification function, recognition time about 1 month or so, is set without extending out
It is standby.It is realized according to the identification of its taiwan area is passed using the statistical of communication success rate, taiwan area recognition success rate is relatively low, is 60-70%.
The advantages of this recognition methods is to be not required to increase any hardware device to realize that taiwan area identifies, disadvantage is：Due to
Narrowband carrier itself communicates that success rate is low, it is accurate, complicated can to use, real-time algorithm realizes taiwan area identification, prediction
Taiwan area recognition success rate is low.
Invention content
To overcome the deficiencies of existing technologies, the technical problem to be solved in the present invention is to provide a kind of knowledges of bandwidth carrier taiwan area
Other method in the case of not increasing any equipment at the scene, can realize high-precision taiwan area identification.
The technical scheme is that：This bandwidth carrier taiwan area recognition methods, this approach includes the following steps：
(1) host node receives triggering taiwan area recognition command；
(2) host node obtains phase identification result, network topology；
(3) host node issues broadcast meter reading order；
(4) it waits for from node module meter reading in 10 minutes；
(5) waiting system is delayed 5 minutes；
(6) it according to phase relation, taiwan area logical topology relationship, neighbor node load, voltage relationship, is identified and is calculated using taiwan area
Method carries out taiwan area identification；
(7) recognition result is exported, is terminated.
The present invention is known according to phase relation, taiwan area logical topology relationship, neighbor node load, voltage relationship using taiwan area
Other algorithm carries out taiwan area identification, therefore in the case of not increasing any equipment at the scene, can realize high-precision taiwan area identification.
Description of the drawings
Fig. 1 show the flow chart of bandwidth carrier taiwan area recognition methods according to the present invention.
Fig. 2 show the flow chart of the execution condition of bandwidth carrier taiwan area recognition methods according to the present invention.
Fig. 3 show the flow chart of taiwan area recognizer according to the present invention.
Specific implementation mode
As shown in Figure 1, this bandwidth carrier taiwan area recognition methods, this approach includes the following steps：
(1) host node receives triggering taiwan area recognition command；
(2) host node obtains phase identification result, network topology；
(3) host node issues broadcast meter reading order；
(4) it waits for from node module meter reading in 10 minutes；
(5) waiting system is delayed 5 minutes；
(6) it according to phase relation, taiwan area logical topology relationship, neighbor node load, voltage relationship, is identified and is calculated using taiwan area
Method carries out taiwan area identification；
(7) recognition result is exported, is terminated.
The present invention is known according to phase relation, taiwan area logical topology relationship, neighbor node load, voltage relationship using taiwan area
Other algorithm carries out taiwan area identification, therefore in the case of not increasing any equipment at the scene, can realize high-precision taiwan area identification.
In addition, the step (2) further includes, judge whether networking metrical information, topology information, phase information obtain,
It is to then follow the steps (3), it is no to then follow the steps (2).
In addition, the step (3) includes obtaining terminal clock, broadcast meter reading order is sent.
In addition, further including judging whether to identify simultaneously 5 times between the step (6) and (7), it is to take 3 knot using 5
Fruit is no to then follow the steps (2) as recognition result.
In addition, in a recognition cycle, when there is node to occur being more than 2 offline events, the broadband for triggering the node carries
Wave taiwan area recognition methods.Specific flow is as shown in Figure 2.
Further, the recognition cycle is 24 hours.
In addition, as shown in figure 3, the taiwan area recognizer includes the following steps：
(a) it obtains the voltage value of all measurement points and average voltage and is compared, obtain single point voltage and survey obtaining
Amount point starts to the voltage change trend during terminating；
(b) first identify all 1 grade of nodes of same-phase module, then identify two level and two level or more agent node module,
Finally identify leaf node；
(c) all nodes select the voltage data of the adjacent child node of same father node to compare, and are judged using voting method
The node that voltage value variation tendency is inconsistent during measurement point starts to end is obtained, which is suspect node taiwan area string
Disturb node；
(d) continuous several times voting formula is used, to confirm that taiwan area identifies.
From using this method efficacy in laboratory figure with using the prior art crosstalk taiwan area spot effect figure comparison as it can be seen that
This method can realize high-precision taiwan area identification.
The above is only presently preferred embodiments of the present invention, is not intended to limit the present invention in any form, it is every according to
According to the technical spirit of the present invention to any simple modification, equivalent change and modification made by above example, still belong to the present invention
The protection domain of technical solution.
