Abstract

Electromagnetic radiation generated by pantograph-catenaries detachment is one of the inevitable problems with the development of high-speed railway this paper is focusing on the generating mechanism and characteristics of electromagnetic noise caused by pantograph-catenaries system. Based on previous research, we build an integrated model of catenaries and locomotive system, and study the electromagnetic disturbance characteristics using software FEKO． The simulation experiment results in the end can not only provide accurate data, but also give a more intuitive understanding of electromagnetic field distribution and attenuation characteristics generated by pantograph detachment. DOI : http://dx.doi.org/10.11591/telkomnika.v12i1.3899

Abstract

This paper put forward a finite element method to study the radio transmission in tunnel electromagnetic environment. The author makes use of software simulation to study the rectangular tunnel model.When varying the electric parameters of tunnel wall, ceiling and floor, this may somewhat influence the propagation characteristics of electromagnetic wave.In order to study the interference properties of underground electric locomotive ,this paper put forward a moment of method (MoM) model to analysis electromagnetic compatibility in roadway.The author makes use of FEKO software to simulate its time-varying and non-linear characteristics ,the simulation results are in good agreement with experimental data .In the end it can be concludeed that this model has practical significance to estimate electromagnetic interference in coal mine. DOI: http://dx.doi.org/10.11591/telkomnika.v11i9.3253
