Safety And Stability

The power communication system based on synchronous digital hierarchy(SDH) optical, transmission technology is an important component to ensure the safety and stability of power network. After, years of development, the network has been gradually mature, but it still has many problems, such as the weak, structure of the communication network, insufficient network transmission capacity, weak network access and network management. Therefore, it is necessary to do the research and take simulation for the power communication system based on SDH optical transmission technology. The paper builds up the simulation, platform of SDH network in power communication system based on the EXATA simulation tools. For SDH, device, we implemented functions including multiplexing, demultiplexing and digital cross-connection. And, the simulation analysis provides a great theoretical support for constructing equipment models and network, topology.
