摘要
针对电气化铁路牵引变电站的实际情况 ,结合变电站自动化系统的发展趋势 ,详细讨论了分层分布式牵引变电站的站内通信及与远方调度中心的通信。站内采用LonWorks测控网与以太网两级通信机制 ,多个变电站与调度中心采用DDN方式组网通信。分析及现场试验有力地表明 ,该方案能满足变电站自动化系统对通信的高可靠性、灵活性和实时性的要求 。
According to the realities of electrified railway traction substation and the development tendency of substation automation system,the internal communication of a hierarchic distributed traction substation and its communication with remote control center are discussed in detail.Dual level communication network of LonWorks and ethernet is used in internal communication,and DDN is used to construct the communication network for substations and control center.Analysis and experiment prove that the needs of substation automation system for reliability,flexibility and real time performance can be met preferably.Furthermore,the solid foundation for unmanned substation can be laid.
