韶山-1型电力机车干扰电流源计算机仿真的研究

A Computer Aided Simulation for the Current Interference Source of the Locomotive SS-1

电力机车的牵引电流,是一个很强的干扰源,它影响电气化铁道附近通信信号设备的正常工作.信号工作者在制定抗扰对策前必须对此电流源进行大量测试.测试系统庞大,测试复杂,计算量大,而且现场情况复杂,难以测到最严重情况.本文提出一种算法,在计算机上仿真合成电力机车的干扰电流波形及频域参数,可借此减少室外测量次数,并可找出产生高次谐波干扰的根源.

The propultion current of electrification is a strong interference source of rail- way wayside signaling and communication equipments.A lot of measurements to this interference are needed & a lot of money are spent in this EMC testing.This paper represents a simulation method which will lessen the times of EMC test and its costs.
