摘　　要：本文介绍了电气设备发射的谐波电流大小以及与设备的哪些参数有关和如何估算大小,指明了近代出现电压型谐波源的谐波量更大,比较分析了单相负载中有不同的谐波源时,如何估算中性线电流IN的大小,简单介绍了谐波阻抗计算的难点所在。This paper introduces the harmonic current value of electric equipment and the related parameters, as well as how to estimate the value. It points out that recently appeared harmonic voltage source has more harmonic. The estimate method of neutral current IN value when single phase has different harmonic source are explained. It briefly introduced the difficulty of calculating harmonic impedance.

关 键 词：电压型谐波源 电流型谐波源 N线电流 谐波阻抗
