1、中文摘要随着牵引供电系统运行、调度和管理工作的日益复杂,研制可靠性高、数据处理功能强、人机联系手段齐全、兼备当地控制和远方监控功能的新型变电所微机集中控制系统势在必行。本文针对电气化铁道牵引变电所的特点,对微机集控系统进行了分析和研究。介绍了采用板级设计和片级设计相结合的设计思路,利用STD工业控制机和Mcs一51单片机实现了一个主从式的多机牵引变电所监控系统方案。根据计算机系统的主要构成形式,对监控系统进行了总体分析,并对系统的软件进行了分析和设计,介绍了主要模块的实现,并分析了系统的抗干扰机理及其抗干扰措施。本系统具有数据采集、处理、故障诊
2、断、监测控制、绘制曲线及记录操作和打印功能,既可在当地对变电所实行监控,又能作为远动系统的终端设备,对传输信息进行预处理,提高远动系统的实时性和数据传输能力,同时在复线电气化铁道上可作为站场隔离开关的二级调度端。该系统可使远动功能与当地控制功能有机地形成一体,具有应用价值。关键词:变电所;集中监控;系统设计;软件分析;抗干扰设计ABSTRACTWiththeoperation,disposalandmanagementofthetractionpowersupplysystembeingmoreandmorecomplicated,itismu
