PTN在智能电网中的应用

The application of PTN in the smart grid

随着技术IT化,网络IP化,数据业务在智能电网通信中占有越来越重要的地位,传统的电力通信技术已经不能解决满足传输的需求,因此,提出通过引入分组传输(Packet Transport Network,PTN)技术,结合已有的SDH网络解决地区通信传输容量不足的问题。介绍了PTN应用的实例,并提出了PTN与SDH技术长期混合使用的设想与方案。

With the IT technology and IP network＇ s development, data business occupied more and more important position in the smart grid communication. The traditional electric power communication technology could not solve to meet the requirements of transmission, so Packet Transport Network （PTN） technology was proposed, Combined with the existing SDH network to resolve the lack of communication and transport capacity. This paper introduced the PTN application instances and put forward the plan and scheme of PTN and SDH technology＇ s mixed use for a long time.
