【摘要】 针对铁路牵引变电所运行状态的计算机安全监控,提出了在电气主接线图中用“色流”代替电流仿真显示的新概念。根据这种思想研究了仿真数学模型、计算方法,结合具体牵引变电所的电气主接线,开发了计算机监控软件。研制的安全监控系统实际运行表明,监控计算机屏幕上的电气主接线图能够实时反应设备运行状态,设备带电情况显示更逼真、操作响应速度快,大大提高了牵引变电所运行状态监控的可视性和可靠性。更多还原

【Abstract】 To the question of computer security monitoring of the operation state of traction substation, a new concept was putforward, that replaced the electric current with the so-called “colored current” in the electrical main diagram. Studying this newconcept, it was worked out the emulation mathematics model and its algorithm. Based on these technologies, combining with aelectrical main diagram of a concrete traction substation, it was developed a Computer Monitoring System of the tractionsubstation. After a long-term running, it was proved that the electrical main diagram on the interface of the System could reflectthe operation status of every equipments in the traction substation realistically and rapidly, and the System could too make quickresponse to the users operates. These advantages had improved the visibility and reliability of the System greatly.更多还原
