智能变电站实时交换通信系统设计与实现

Design and Implementation of a Real-time Switching Communication System for Intelligent Substation

智能变电站对通信时延有严格要求,工业以太网在这方面尚不满足要求。为此提出一种用于智能变电站的新型实时交换通信系统架构及其实现方式,利用分组交换、时分复用、通信资源预分配、无源光网络等技术,显著改善了业务的实时性能,提高了通信网络的可靠性和通信资源的可管理性。

Performance of the communication time delay in the industrial Ethernet can not meet the stringent requirements of intelligent substations. This paper proposes a new real-time switching communication system, which uses packet switching, time division multiplexing, pre-allocation of communication resources and passive optical network technology. The proposed solution can significantly improve the real-time performance of the commnnication system in intelligent substation, and then improve the reliability of the communication network and the manageability of communication resources.
