摘要
文章通过对分组传送网(PTN)网络特点、技术优势和实际应用进行分析,结合祁门供电公司现有通信网结构状况,提出利用PTN传输设备组网,对原有地区通信传输网络进行改造,最终制定了承载县域电力调度数据网的建设方案。经过承载业务能力和设备硬件性能的测试,结果表明PTN传输网络切实可行,大大降低了通信组网成本,提高了电力调度自动化系统的安全性,能为调度数据的远程传输提供可靠的通道。
This paper analyzes the characteristics, technical advantages and actual applications of the PTN network, proposes a networking method using the PTN transmission equipments according to the structure situations of the existing communication network. By upgrading the original communication transmission network, a construction solution of county-level power dispatching data network is established. Results of business capacity testing and hardware performance testing show that the transmission network based on the PTN technology is feasible, its communication cost is greatly reduced, and the improved security of power dispatching automation system can provide for remote transmission of dispatching data a reliable channel.
