Abstract:An essential feature of energy internet is the two-way interaction between energy supply and consumption through advanced communication network. Therefore, the optimal configuration of highly reliable communication network based on optical fiber communication to meet Quality of Service(QoS) requirements of multiple services has become a key problem to be solved urgently. Starting with the reliability of power fiber transmission network and considering the multi-QoS transmission demand of power communication service, a circuit configuration optimization method based on compound measurement is designed. The new method is different from the traditional shortest path configuration algorithm. In one configuration process, m feasible configuration schemes are planned at the same time. In addition, the reliability of the entire optical path and different measurements of the path set, such as bandwidth, delay, packet loss rate, attenuation and cost, are analyzed. Finally, the optical path configuration scheme that meets the requirements of reliability and transmission QoS is finally obtained, and the priority selection sequence is given. The optimized configuration of multi-circuit will effectively improve the reliability of power communication and also provide a guarantee of circuit configuration for future multi-channel flow allocation. In the simulation of 35~500 kV power communication station network in an urban area, the new configuration method can obtain four transmission circuits that meet the demand of multi?QoS at the same time to realize the protection of main and standby circuits, which is of great theoretical significance to planning and operation optimization of the power optical transmission network and to the improvement of the resource allocation ability and reliability of the power communication network.
