轨道电路的地磁感应电流监测数据分析
|
摘要
为了研究轨道电路地磁感应电流(GIC)监测数据特征及影响因素,对2015年6月23日京港客运专线鹤壁东站轨道电路GIC监测数据进行统计分析。轨道电路GIC监测数据与子午工程观测台站武汉九峰站地磁场数据有较强的相关性,与地磁场北向分量和东向分量显著相关,从统计学角度论证了轨道电路中监测电流主要由地磁暴产生。采用小波去噪法对轨道电路GIC监测数据进行降噪处理,可有效提高与地磁数据的相关性,并与平面波模型和分层大地模型的计算感应地电场进行多元回归分析,得到京港客运专线石武段轨道电路GIC的经验模型。研究结果可用于轨道电路GIC预测及特性分析,有助于理解地磁暴对信号轨道电路系统的影响。同时,轨道电路电磁环境复杂易受干扰,对轨道电路的GIC监测及模型建立提出了新的挑战。
To study the impact of geomagnetic storm on the track circuits in the high-speed railway,geomagnetically induced current(GIC),captured in the track circuit at the Hebi East traction power supply substation of the Beijing-Hong Kong Dedicated Passenger Line on 23 June 2015,were analyzed with the geomagnetic data obtained from the Chinese Meridian Project.The data show a high correlation for the Jiufeng geomagnetic Observatory,and it was verified that the current captured in the track circuit was caused by the geomagnetic storm from the point of static view.The GIC were denoised using the interval-dependent denoising method,and presented a regression analysis with the calculated geoelectric fields using the plane wave method and the layered earth model.This paper,related to a project about GIC in the high-speed railway,thus provides a tool for understanding space weather effects on the signal system.The results bring out the high challenge of making such measurements in a complex electromagnetic environment and a stimulus to further research for modelling and measuring GICs in the rail systems.
