Description

Power communication communication terminal special
Technical field
The present invention relates to power system telecommunications technology field, particularly relate to a kind of power communication communication terminal special.
Background technology
Along with the development of electrical network, power communication has been widely used in the links such as electrical network production control, management, operation.In recent years power network development important directions---intelligent grid, exactly take the advanced communication technology, sensor technology, information technology as basis, take the information interaction between grid equipment as means, to realize power grid security, reliable, economic, the energy-conservation advanced modern power industry system as object.Intelligent grid new business is mainly reflected in adapted electrical domain, and as " neural net " of intelligent grid, greatly developing and building distribution communication network has been trend of the times.
At present, power communication major network and distribution communication networking figure, as shown in Figure 1, Fig. 1 is power communication major network and distribution communication networking topological diagram.Due to 10kv and following distribution net work structure complexity, controller switching equipment quantity is many, branch line is many, widespread feature, distribution operation class business has wiring complexity, has a very wide distribution, communication point is many, poor, the single communication point amount of information of communication device works environment little (only hundreds of baud) but the very huge feature of amount of information of basic database causes the construction and development of present stage distribution communication construction to have many obstacles.
In Distribution Network Communication mode, optical fiber communication is the best communication mode of communication efficiency, but expensive, constructional difficulties, and the duration cannot be determined; The wireless public network communication of renting telecom operators is both economical communication modes, but cannot meet the communication requirement of distribution automation, distribution network protection and service control, and network is not controlled.There is the problems such as communication delay is large, communication port is unstable, the power failure of construction need in medium voltage electricity line carrier communication, is eliminated gradually.
Compared with optical fiber communication, power line carrier communication, new generation of wireless broadband connections technology has that non line of sight transmittability is strong, opposing natural calamity ability is strong, long transmission distance, be with roomy, be not limited to the advantage gesture such as ground line structure.Therefore, building electric power WiMAX private network becomes the focus of current intelligent grid power communication research, State Grid Corporation of China has listed " broadband wireless communication technique " in one of support technology of intelligent grid communication access net construction scheme, south electric network has also been strengthened emphatically the research of wireless broadband communication technology, and using wireless broadband communication technology as " 12 " adapted communication system of power grids primary study content.Therefore, the following distribution communication technology should be that light communication and wireless private network are applied as master, and wireless public network is supplementary communication pattern.And TD-LTE(Time Division Long Term Evolution, timesharing Long Term Evolution) as the main flow 4G wireless broad band technology with independent intellectual property right, the one preferred technique as construction electric power WiMAX private network by various places grid company, according to the relevant policies of national radio supervision department, what power grid construction TD-LTE electric power WiMAX private network adopted at present is 1785MHz-1805MHz frequency range equipment, generally adopts wherein 5MHz bandwidth.
The networking plan that existing Fibre Optical Communication Technology is communicated by letter at power distribution automation with TD-LTE electric power WiMAX private network technology, specific as follows:
Adopt the distribution automation business of optical fiber access, DTU(Distrubition Terminal Unit in electricity room, switching station terminal equipment) terminal adopts RJ45 interface to be connected with the access industrial Ethernet switch in power distribution room, and power distribution automation business datum is passed through distribution telecommunication optical fiber communication network and is transferred to power distribution automation main website.If this DTU terminal is only supported RS232 serial ports, cannot access by optical fiber industry switch, can only be by GPRS wireless public network or medium-voltage carrier access.

Adopt optical fiber access for the power distribution room that possesses optical fiber laid condition, the electric room that possesses TD-LTE wireless private network signal coverage condition adopts wireless private network access.
Mainly there is following problem in technique scheme:
(1) power distribution network city optical-fiber communication channel is vulnerable to outside destroy, and reliability is low;
For example, due to city geographical environment complexity, the distribution duct fiber cable laying in dense city is easily bitten or suffers broken the outside destroy such as drainage construction by mouse, causes power distribution automation optical-fibre channel discontinuity events to take place frequently.
(2) optical cable is longer destroyed rear repair time;
For example, distribution optical cable repair complex procedures, continues and needs certain instrument, equipment and technology, causes the destroyed rear power distribution automation communication port of distribution optical cable long recovery time.
(3) Reliability of Wireless Communication is not as good as optical fiber communication;
For example, dense city electromagnetic environment complexity, CPE communication terminal signal is subject to electromagnetic environment and disturbs, blocks impact, causes communication to go offline, and makes poor stability, the reliability of wireless private network communication low, far away from optical fiber communication.
(4) optical fiber communication cannot support to adopt the DTU terminal of serial communication;
For example, part is only supported the serial communication of RS232 compared with the DTU terminal of old type tube, cannot utilize industrial switch, EPON etc. not to support the optical communication equipment access of serial ports, can only adopt GPRS wireless public network or medium-voltage carrier access.
In sum,, there is reliability, poor stability and use circumscribed problem in existing power telecom network.
