Description
Technical field
The present invention relates to electric power low-pressure distribution network technology field, more particularly to it is a kind of based on the low of the work frequency carrier communication technology
It is press-fitted net topology automatic identifying method and system.
Background technology
Low-voltage platform area power distribution network carries the key functions of power network end feed household electricity, wherein passing through low-voltage distribution
System topological automatic identifying method come calculate garden, cell, in building each electrical equipment annexation, and with certain mode
These annexations are stored, topological analysis is in the calculating of low-voltage distribution system damage, energy-saving analysis in highly important
Position.If low-voltage network family variable topological relation occurs wrong, serious shadow can be produced to the accuracy of taiwan area line loss calculation
Ring, in addition it is serious the economical operation of power network can also be adversely affected, it may cause low-voltage network topological relation wrong
By mistake the reason for, mainly there are two kinds of reasons:First, due to low-voltage network construction period electric supply meter circuit archives mistake cause it is low
It is press-fitted power grid topological relation mistake；Second, low-voltage platform area power distribution network breaks down, when adjusting wiring in inspection repairing, change
Ammeter archives do not record or misregistration causes low-voltage network topological relation mistake.Traditional low-voltage distribution net topology identification
Detection rely primarily on manual inspection means, i.e., according to low-voltage platform area power distribution network be distributed and move towards, using hand-held family become identifier by
Duan Jinhang is manually generally investigated, and because low-voltage network net distribution circuit is more, cable duct or overhead transmission line parallel laying, inspection is not
But efficiency is low, cost is high, and low-voltage platform area family variable topological information can not be obtained in real time, exactly.
Therefore, the importance for avoiding taiwan area power distribution network topology status inaccurate is exactly that to carry out taiwan area accurately and in time low
The identification of power network topology status is press-fitted, becomes relation so as to correct wrong family as early as possible, avoids grid line loss calculating and economical operation from going out
Existing problem.
The content of the invention
Refer to that the transformer installed in somewhere namely refers in dress, certain station power distribution run about " platform change " in the present invention
Transformer and " taiwan area " refer to that platform becomes the regional extent of power supply, and it is the technical term of this area power industry.
For in the prior art the defects of, the invention provides a kind of low-voltage distribution network based on the work frequency carrier communication technology to open up
Flutter automatic identifying method and system.
To achieve these goals, the technical solution used in the present invention is：
A kind of low-voltage distribution network topology automatic identification method based on the work frequency carrier communication technology, comprises the following steps：
(1) installation of equipment, a concentrator and a topology are installed beside each transformer of low-voltage distribution network taiwan area
Automatic identification equipment, it is connected between concentrator and topology automatic identification device by 485 circuits, is being distributed in low-voltage distribution network platform
It is internal or external on area's intelligent electric meter to have bimodulus collector, distribution is being installed positioned at power marketing center or electric power inspection department
Net topology Intelligent Recognition main website；
(2) identification process, topology automatic identification device or concentrator pass through low-voltage distribution network circuit (220V circuits and 485 lines
Road) to be distributed on low-voltage distribution network taiwan area intelligent electric meter it is internal or external have bimodulus collector send the multichannel based on wave distortion
Topological identification signal, in order to adapt to low-voltage network circuit complex distribution, the more situation of all kinds of electrical equipment interference, multichannel topology
Identification signal is transmitted using special distorted waveform on distribution network line, and the identification signal frequency is low, and with preferably anti-
Interference performance, transmission range is more than 2000m, it is not necessary in taiwan area separately laying-out, is distributed in low-voltage distribution network taiwan area intelligence electricity
Internal or external bimodulus collector reads the GPS information of intelligent electric meter, terminal iidentification coding, geocoding and address code on table
The end topoligical node information data that ammeter and platform become is combined into, every intelligence electricity is formed by end topoligical node information data
Original topological link relation table information data of table, and it is distributed in low-voltage distribution network taiwan area in pre-existing bimodulus collector simultaneously
Internal or external bimodulus collector generates new topological link relation table data, institute after receiving topological identification signal on intelligent electric meter
State bimodulus collector original topological link relation table information data compares with new topological link relation table data, if different
Normal then generation topology status displacement event, while substitute original topological link relation table information with new topological link relation table data
Data, and new topological link relation table data are stored in bimodulus collector, sending poll in topology automatic identification device recruits
When calling out instruction, being distributed in bimodulus collector internal or external on low-voltage distribution network taiwan area intelligent electric meter will most newly-established topological chain
Connect relation table data to carry out being uploaded to topology automatic identification device, topology automatic identification device closes most newly-established topological link
It is that table data upload to power distribution network topological smart identification main website, distribution net topology intelligence by GPRS radio channels or 4G radio channels
