基于ASON技术的渭南SDH网络改造

文章分析了ASON网络的结构特点、技术优势和业务保护方式,结合电力系统中光纤通信的现状,给出了渭南电力通信SDH网络与ASON网络的融合方案,即以330 kV变电站、中心站等为主要节点组建Mesh网络结构,在其边缘节点以单点或多点接入SDH环网。实践证明,在电力系统通信网中引入ASON技术可显著提升业务保护性,提高带宽利用率,改善网络可靠性和安全性,对网络建设具有借鉴意义。

Transformation of Weinan SDH Network Based on the ASON Technology

The paper analyzes structural characteristics, technology advantages and business protection modes of the ASON technology, and provides a scheme of integrating the SDH network and the ASON network in Weinan electric power communication by considering the situations of optical communication in the electric power systems. The proposed scheme builds a Mesh network by taking the 330 kV substation and center-stations as main network nodes, and accesses to the SDH network through its fringe nodes by a single point access mode or multi point access one. The practical results show that the power communication network using the ASON technology can not only observably improve the protection capability, promote the bandwidth utilization and improve network reliability and security, but also provide a reference for network constructions.
