引言高速公路供配电系统是智能交通的基础,供配电的可靠性直接影响高速公路收费、监控及通信系统的正常工作。供配电系统的可靠性还关系到人身财产的安全,特别是有隧道的高速公路,短暂的供配电故障可能会导致交通事故,造成重大的损失。高速公路的供配电质量需要提高,实现变电所自动化是必由之路。变电站综合自动化系统在高速公路的发展起步比较晚,近几年才刚刚兴起。目前,国内高速公路变电所综合自动化系统的实施只是探索阶段,已实施的系统参差不齐。本文以变电站综合自动化系统在天汕高速中的应用进行探讨,供业内同行参考。
INTRODUCTION Expressway power supply and distribution system is the basis of intelligent transportation. The reliability of power supply and distribution directly affects the normal operation of expressway tolling, monitoring and communication system. The reliability of power supply and distribution system is also related to personal and property safety, especially the tunnel with the highway, a short supply and distribution failures can lead to traffic accidents, resulting in significant losses. The quality of the power supply and distribution needs to be improved, substation automation is the only way. Substation automation system in the development of the highway started relatively late, only in recent years has just risen. At present, the implementation of the integrated automation system of the domestic expressway substation is only an exploration stage, and the implemented system is uneven. This article discusses the application of substation integrated automation system in the days of the high-speed, for the industry counterparts reference.
