Description
Technical field
The present invention relates to one kind for distribution network automated field of information transmission wirelessly to match electricity automation information collection
System and one kind wirelessly match electricity automation information collecting method.
Background technique
The communication system of Automatization in Power Distribution Network is smart grid important component, is in recent years raising power distribution network
Reliability of operation carries out smart grid construction comprehensively, and specifies building through power generation, route, power transformation, distribution, power supply service
With the power grid sustainable development system for dispatching whole links and full voltage grade " thinking of development.Wherein, distribution network automated system
System directly decides experience of the electricity consumer for power quality, and area coverage is wide, technology implements means diversification, system
Construction period is long and difficulty is larger, becomes a major issue of China's construction smart grid.
Communication technology in distribution automation common at present has following several.
1. the wire communication based on power line carrier, power line carrier communication (PLC) is the distinctive communication party of electric system
Formula, it modulates data into carrier signal or spread-spectrum signal using existing power line, is then coupled to friendship/straight by coupler
In the galvanic electricity line of force.PLC have many advantages, such as it is easy to maintain, easy use, be at low cost, but its power line intermittence noise is larger, signal declines
Subtract serious, line impedance often fluctuate, large-scale network-estabilishing it is extremely difficult, it is not high to be usually applied to real-time, reliability requirement
In system.
2. the optic communication based on SDH/MSTP, SDH/MSTP technology is the mainstream technology of power telecommunication network, in trunk
Very widely used in electric transmission network, it is with property such as high-transmission bandwidth, a variety of looped network protection agreements of support, strong interference immunities
A healthy and strong platform can be provided for power communication.But in distribution network automated communication, SDH equipment wants its working environment
Ask higher, bandwidth availability ratio is lower, difficulty of construction is larger, higher cost so that SDH/MSTP technology automates in power distribution network
It is unrealistic using some in system.
3. being based on the optic communication of " RS232/485 light cat ", being using light cat (Modem) networking will using light cat equipment
RS232/485 signal carries out long range extension, so that distribution power automation terminal is connected with RS232/485 bus mode,
Uplink communication interface is converged by protocol conversion device in communication substation.A large amount of distribution power automation terminal equipment passes through light
Fibre is concatenated, networking is simple, low in cost, configuration flexibly, but it cannot achieve united net management between substation device, communication
Low efficiency can not carry that large capacity Ethernet data, anti-electromagnetic interference capability are poor, fiber resource utilization rate is low.
4. the optic communication based on industrial ethernet switch, industrial ethernet switch has high bandwidth, looped network protection, IP
The advantages that change trend, but it moves towards more demanding to power distribution network optical fiber, is unable to satisfy the point-to-multipoint communication knot of Distribution Network Communication
Structure, dilatancy, the failure of anti-multiple spot etc. require.
Summary of the invention
It is a kind of wirelessly with electricity automation information collection the purpose of the invention is to overcome the deficiencies of the prior art and provide
System and one kind wirelessly match electricity automation information collecting method, inexpensive, safe and efficient distribution network automated to realize
Communication.
Realizing a kind of technical solution of above-mentioned purpose is: it is a kind of wirelessly with electricity automation information acquisition system, including match
Power consumption management component, power distribution station, subscriber station and other power stations,
Protocol converter and wireless module are equipped in the power distribution station, the subscriber station and other described power stations；
The power consumption management component of matching includes sequentially connected connection router, hardware firewall and interchanger, Yi Jizhi
Few two are matched power consumption management host, described to connect respectively with the interchanger with power consumption management host；
The wireless module and the router are wirelessly connected.
Further, stating wireless module is 3G/4G communication module.
Further, stating wireless module is 3G/4G modem.
One kind of the invention wirelessly matches electricity automation information acquisition system, installs protocol conversion device and nothing additional in terminal side
Wire module, protocol conversion device are used to for the serial ports specification of terminal side being converted into network specification, and wireless module is wireless to carry out
Data transmission.The client virtual Intranet that transmission is identified using the dedicated APN of 4G APN network insertion, access path are isolated with public network
So that it is guaranteed that the safety of network access and the privacy of data transmission.Topological structure with power consumption management component can guarantee data
The reliability of transmission, and polygamy power consumption management host can be met while carrying out data processing.One kind of the invention wirelessly matches electricity consumption
Automated information acquisition method cooperates this wirelessly to match electricity automation information acquisition system to carry out data transmission, and successively operation can be protected
Demonstrate,prove stability, privacy and the reliability of data transmission.
Compared to more distribution network automated several traditional communication technologys, the wireless communication that this system uses has following excellent
More property:
1. network deployment is flexibly, can rapid deployment；
2. initial investment cost is relatively low, investment cable resource is not needed；
3. being easy to implement to distribution side large area rapid Cover；
4. later period dilatation and network are easy to adjust.
Detailed description of the invention
Fig. 1 is the topological structure schematic diagram that one kind of the invention wirelessly matches electricity automation information acquisition system.
Specific embodiment
