Simulation and application of power transmission network based on SDH
Abstract
The architecture of power optical transmission network simulation was proposed from the equipment layer,network layer and business layer for the target of communication support system for power grid control business,and the principle of SDH prototype simulation based on SSFNET was presented,and the design idea and implementation method of SDH device,network protection and recovery and associated alarm function was described in detail.Finally an example about the SDH communication topology of stable system in Northern Jiangsu Province was given,it realized the basic function of service bearer,fault alarm,channel recovery,route reconstruction,delay monitoring of power optical transmission network,which would provide quantitative analysis method for the communication network risk assessment,fault simulation,and the interaction effect of the power grid control system.
