Abstract: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 cannot 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 cannot 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.
