Optimization of Power Communication Network Based on SDH Self-Healing Ring Network Technology

With the increase in the service demand of the power communication network and the potential impact of the malfunction, whether the results of the artificial configuration can adapt to these changes in the future and a more suitable planning scheme of the network topology is existing, which can make the entire network achieve a better operating condition. Through the field investigation, the services carried by the power communication network of a certain place are pre-configured, that is to say, the time slots of each service on the SDH optical transmission network are fixed and artificially configured. The specific case is explored by the developed simulation software, and the rationality and reliability of the existing services and self-healing planning in the simulation process are evaluated comprehensively to predict the impact of the service transmission caused by the link failure in this paper. Finally the optimization suggestion is provided for the node, link and the system protection of the existing grid planning in the region to improve the performance indicators of all aspects of the network.
