Abstract

This paper preliminarily examines the applicability of Internet protocol (IP)-related communication technologies such as IP and MPLS (Multi-Protocol Label Switching) routers and L2 (Layer-two or Ethernet) switches to existing teleprotection systems. The teleprotection systems concerned include microprocessor-based current differential teleprotection with data communications of instantaneous current values or phasors, directional comparison teleprotection, and special or system-wide protection. Taking account of the performance limitations of IP-related telecommunication networks, fully redundant L2 switch networks are indispensable, as is an external timing synchronization scheme for current differential teleprotection. Based on the analyses, a new concept for modernizing teleprotection system associated with L2 switch networks, time synchronization and modular devices is proposed.
审查与ip有关的通信对远程保护系统的适用性
本文初步探讨了与互联网协议(IP)相关的通信技术,如IP和MPLS(多协议标签交换)路由器和L2(第二层或以太网)交换机对现有远程保护系统的适用性。所涉及的远程保护系统包括具有瞬时电流值或相量数据通信的基于微处理器的电流差动远程保护、定向比较远程保护和特殊或系统范围保护。考虑到与ip相关的电信网络的性能限制,完全冗余的L2交换网络是必不可少的,电流差动远程保护的外部定时同步方案也是必不可少的。在此基础上,提出了一种与L2交换网络、时间同步和模块化设备相结合的远程保护系统现代化的新概念。
