摘要
以电网控制业务的通信支撑系统为目标,提出了从设备层、网络层和业务层进行电力光传输网仿真的体系架构以及在SSFNET(scalable simulation framework network)平台基础上进行SDH(synchronous digital hierarchy)原型机仿真的实现原理,详述了SDH设备逻辑部件、网络保护与恢复和关联告警功能的设计思路及实现方法,最后以承载苏北安稳系统的SDH通信拓扑结构为实例,实现了电力光传输网络的业务承载、故障告警、通道恢复、路由重建、时延监测的基本功能,为通信网络风险评估、故障模拟以及与电网控制系统的交互影响提供量化分析手段。
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.
