在监控系统与被控站通信网以及变电站自动化通信网中,实施光纤以太网替代传统串口总线通信方案能显著提高自动化系统的性能。该技术成功应用于上海轨道交通4号线工程,有效发挥了光纤以太网的优势,明显提高了变电站综合自动化的通信效率。 In the monitoring system and the controlled station communication network and substation automation communication network, the implementation of optical fiber Ethernet instead of the traditional serial bus communication solutions can significantly improve the performance of the automation system. This technology has been successfully applied to Shanghai Metro Line 4 project, which has effectively brought into play the advantages of optical fiber Ethernet and significantly improved the communication efficiency of substation automation.
