Research On Engineering Application Of PTN In Electric Power Communication Network

Electric power communication network is an important mean to ensure the power production,stability,electric operation,carrying distribution automation,electric energy data acquisition,load control and management and many other business,which is very important and in the initial stage of construction currently.Along with the advance of power production information and continuous improvement of power dispatching automation,a variety of production and management of information gradually is diversified,and toward the direction of evolution of ALL IP.Distribution communication network,there are different requirements for information partition,security,real-time,reliability of distribution network business,which needs hierarchical management service provided by communication network.At pressent,the commonly used EPON,industrial Ethernet switches,SDH/MSTP technology can not achieve the hierarchical management but use multiple sets of equipment to achieve the physical isolation,which support different business systems,each set of equipment is runninga single business,the bandwidth utilization is low,the construction is repeated and the expansion cost is much high.So this paper has proposed PTN to solve the problem of distribution communication network of ingrated transport services based on the project”Research on hybrid networking technology of distribution communication network combining micro power wireless,PTN,EPON”.This study analyzed the characteristics of the power distribution communication network built PTN, solved the original equipment repetition of electric power communication system and can not share the bandwidth resources tested the traditional network technology on the bearing with electric power communication network business ability, compared the differences in PTN and traditional electric power communication network networking technology;In detail elaborated the PTN adapt ability in electric power communication network, analyses the PTN technical specification on electric power business indicators meet the situation; Build a typical network topology of distribution network communication network and the power distribution communication network layered structure design and equipment configuration, put forward the distribution network plan and protect the rearrangement of the school, the PTN business in electric power communication network load and network synchronization performance are analyzed in test.Through the comparison and analysis of technology and network test show that the PTN technology in power with communications networks, have more business isolation of SDH equipment and the Ethernet business carrying capacity, satisfy with the electric communication network construction at the present stage.
