基于计算机仿真的铁路、机场电磁兼容评估

为解决电气化铁路与沿线机场导航台站的电磁兼容问题,引入计算机电磁仿真平台进行仿真评估。以西安至延安高速铁路为例,首先利用Rainbow电磁仿真平台,对机场周边地理、地形环境,导航台站天线辐射特性进行联合建模;然后,利用仿真模型,在超级计算机平台对各工作场景下的台站工作性能进行量化评估。评估结果显示,西延高铁设计方案满足机场电磁环境相关标准。利用计算机仿真技术进行铁路、机场电磁兼容评估,将理论模型与实际场景相结合,既满足了理论推导的科学性,又兼顾了具体场景的差异性,具有较高的推广价值。

Evaluation of Electromagnetic Compatibility Between Railway and Airport Navigation Facilities

To address the electromagnetic compatibility(EMC)problem between the electrified railway and the airport navigation station,computer simulation technology is adopted.With reference to Xi’an to Yan’an High-speed Railway,the joint modeling of geographical conditions and navigation antennas is carried out by using Rainbow electromagnetic simulation platform.Then,the performance of each navigation station in each working scenario is evaluated on the supercomputer platform with the built model.The results show that the design of Xi’an to Yan’an High-speed Railway meets the standard requirements of EMC.The EMC evaluation,based on computer simulation,not only satisfies the scientific standard,but also takes into consideration the differences of practical scenarios.It is believed that the proposed approach is worth to be popularized.
