摘要
2012—2013年,太阳活动将进入高峰期,对工业系统会造成较大的风险和影响。在调查和研究太阳活动所导致的国外轨道交通设备故障的基础上,从信号系统、电力牵引系统等方面,针对太阳活动对我国轨道交通系统可能造成的影响进行了简要分析,对疑似案例进行了罗列并与当日前后的太阳活动情况对照,认为在轨道交通领域开展这一研究具有紧迫性和必要性。并提出了若干建议:在分析故障成因时,将太阳活动作为一个值得重视的因素加以考虑;在太阳活动的高峰期,有必要对轨道交通设备中的GIC(地磁感应电流)等数据进行监测。在轨道交通的信号、通信和电力方面应加强抗干扰措施和维护力度,以应对太阳活动高峰期。
A peak of solar activity will happen from 2012 to 2013 ,which may cause risks in industrial systems. Based on researches about foreign railway faults caused by solar ac- tivity, the impact of solar activity on railway signal and e- lectric traction equipment is briefly analyzed. This is an ur- gent and necessary issue to be studied. In this paper, some suspected cases are listed and compared with the condition of solar activity,suggestions are also proposed to cope with the peak of solar activity.
