电气化铁路与机场导航设施的电磁兼容

研究目的:电气化铁路对机场导航设施的电磁干扰影响,应执行国标GB 6364的相关标准。胶济电气化铁路与青岛流亭机场导航设施间的防护距离不能满足防护标准,采用技术可行经济合理的电磁兼容措施,避免铁路改线或机场搬迁。研究方法:通过理论分析,找出相互间电磁兼容的条件,并通过实测验证,为设计提供防护依据。研究结果:推荐“现状电化”方案,并提出备用方案和应急方案。在电气化铁路具备通电条件后,实施校验飞行和防护效果检测。研究结论:对不满足国标规定的导航设施,对无源干扰和有源干扰作理论分折,为设计提供理论根据。并通过现场实测和校验飞行,验证分折结论。满足常规电气化铁路常速运行的电磁防护标准,在高速铁路200 km/h条件下也同样能满足防护标准。

Electromagnetic Compatibility between Electrification Railway and Navigation Facilities

Research purposes: Electromagnetic interference of electrification railway to navigation facilities of airfield must be obeyed to GB 6364.The defending distance between Jiaoji electrification railway and navigation facilities of Qingdao Liuting airfield can not satisfy the defending standard.For avoiding relocating the railway line or the airfield,the electromagnetic compatibility measures should be researched in view of both economic and technical factor.Research methods:Through theory analysis,the conditions of electromagnetic compatibility each other are found.And defending basis is provided for design through field testing and validation.Research results:This paper recommended the scheme for "Current Situation of Electrification" .At the same time,this paper also proposed standby scheme and emergency scheme.In order to ensure flight safety,the checkout of(aviation) and the verification of defending effect should be implemented after electrification railway has the condition of power supply.Research conclusions:Passive interference and active interference of navigation facilities,which can not satisfy national standards,are analyzed and the conclusions can provide the basis for design in theory.At the same time,the(conclusions) are verified through field testing and aviation checkout.The electromagnetic defending standards are satisfied both in conventional speed and in 200 km/h high-speed of the electrification railway.
