面向智能电网的蛛网动态多径链路路由机理研究

Smart Grid (SG) has put forward many higher requirements to electric power telecommunication network, such as safety, reliability, real-time and so on. This project is set in application of smart grid, selecting transformer substation as main application objects. In the view of natural spider web structure and spider predatory process, this project will concentrate on the related research on the high reliability mechanism and the deterministic time theory of dynamic routings with multiple communication links based on artificial cobweb, which will include the following items:.(1) The preliminary theory of fast routing method will be studied, and the related algorithm of routing driven by multilevel hybrid addresses based on information fusion of geography and cobweb coordinate will be provided. This work will advance the rapidity of routing. .(2) The basic theory of redundancy routing based on multiple communication links status for communication between the typical large nodes such as transformer substations etc.and between the small nodes (such as IEDs)(within cobweb) will be researched, and the mechanism of transferring same data packets on multiple communication links simultaneously will be explored. This work will improve the reliability of routing..(3) The deterministic principle of data transmission time on communication links oriented QoS will be considered, and the virtual links model of multiple parameters scheduling and MPLS routing will be studied. This work will demonstrate the time determinacy of routing..(4) The typical node model, virtual central node model and their application model of artificial cobweb in smart grid will be discussed in detail, and the preliminary theory and its simulation platform for communication in smart grid will be built to check the correctness of the theories..All above will provide the novel fundamental theory for building the electric power telecommunication communication network with reliability and time determinacy routing.
