摘要
随着智能电网的迅速发展,通信网络在电力系统中的作用日益重要.同步数字体系(Synchronous Digital Hierarchy,SDH)技术凭借其高带宽、低延迟以及高可靠性,成为智能电网通信的关键技术之一.文章探讨了SDH技术在智能电网中的应用基础,并从网络拓扑优化、带宽资源管理、数据传输效率提升及故障检测与恢复机制等方面提出优化策略,最后分析SDH技术在变电站、电力调度、配电网以及智能电表等通信系统中的应用.
Abstract
With the rapid development of smart grids,the role of communication networks in the power system is becoming increasingly important.Synchronous Digital Hierarchy(SDH)technology has become one of the key technologies for smart grid communication due to its high bandwidth,low latency,and high reliability.This article explores the application foundation of SDH technology in smart grids,and proposes optimization strategies from the aspects of network topology optimization,bandwidth resource management,data transmission efficiency improvement,and fault detection and recovery mechanisms.Finally,the application of SDH technology in substations,power dispatching,distribution networks,and smart meter communication systems is analyzed.
