Optical Communication Technology In Power Line Communication System And Network Research Program

In this paper, I study the power industry and power communication systems, including for transmission and substation of electric power communication network characteristics, distribution of electricity for power distribution characteristics of communication networkfor, statistical power for electricity meter reading communication system characterized by centralized. I found the power system is now widely used means of communication with PLC Power Line Communication+ RS232/RS485 bus connections, using fiber optic transceivers+ RS232/485 bus connections, use the 230M data radio communications, using GPRS communication methods.Which, PLC Power Line Communication,230M data radio transmitted rate is low, defects and poor anti-interference ability, but by way of fiber optic transceivers to connect the low transmission rate, RS-232 bus cable and power cable laying prone with the path of electromagnetic interference generated other defects, GPRS the same way there is a low transmission rate, and take the initiative in hiring public network without problems.Power communication systems, assume the power of main station and between the power system secondary equipment remote monitoring, remote communication, remote debugging, remote control information transmission function the grid resource scheduling work is exceptionally important. How to meet the communication system, power system reliability, high standardized, high-bandwidth nature of investment and economic requirements, is the present and for the next quite a long time now, the face and resolve important issues.In this paper, I am a new means of communication 3G, WiMAX and optical fiber communication in the technical characteristics, reliability, construction costs were compared. I concluded that optical communications is the future direction of development of electric power communication system.In this paper, I further discussed the communication optical fiber communication system applications in power feasibility study in electric power communication network, power distribution communication network, respectively, in what light the most appropriate means of communication.In this paper, optical communication system applications in power feasibility study in electric power communication network, power distribution communication network, respectively, in what light the most appropriate means of communication.I passed on the existing access to a large number optical communications business of DWDM, OTN, ASON, EPON and other technical characteristics, to build the net maturity for analysis and reference to large network telecommunications operator case. Come the existing power dispatching network and power distribution network communication using optical fiber communication can, and draw a conclusion:In electric power communication network in the networking and telecommunications operators are now fully consistent network of electric power network can be applied to more higher rate DWDM wavelength system, the future system can transition to the OTN network.Communication in power distribution network, the widespread use of telecommunications operators EPON broadband access communication system transplant, is a very good choice. EPON technology high network security, expansion of convenient, easy to maintain, but also save construction costs, possible future transition to GPON system network.
