d Ionl一qlony旧gooe}x{ebo电j]牵引高次谐波(harmonies of eleetrietraction)整流式交流电力机车在整流过程中将引起交流侧电流、电压波形畸变,按傅立叶级数分析该畸变波形可分解成频率为基波频率整数倍的一系列高次谐波分量的叠加。 高次谐波电流、电压可引起下列不良影响: (1)对通信线产生杂音干扰影响; (2)引起电力系统中其他电力电容器设备的过负荷; (3)当电气化铁路负荷某次谐波电流频率与电力系统自身谐振频率相近时,可产生电流谐振,使该次谐波电流在电力系统中放大,危及电力系统安全运行; (4)使旋转电机、变压器、电力电缆的出力减少并产生过热,影响电气设备寿命; (5)造成继电保护误动或仪表读数误差; (6)使半导体开关元件换相失灵。 为限制谙波的危害,各国都规定了允许谐波含量的标准(见供电质童)。 为降低电力牵引负荷产生的谐波,在电力牵引变电所和电力机车中可装设由电容、电感组成的谐波吸收装置。交流一直流一交流电力机车利用电力电子技术,可实现低谐波分量的负荷特性,使谐波含量降低。
