摘　　要：由于变压器励磁的非线性特点,在电力系统谐波潮流分析时,必须把变压器作为一个谐波源来考虑。本文利用磁化曲线的解析分析,提出了变压器磁化支路谐波电流的估算方法。Owing to the non-linearity of the magnetising characteristic of powertransformer, the transformer should be considered as a harmonic source in analysing theharmonic power flow of a power system. An evaluation method for the harmonic currentof the power transformer magnetising branch, through the analysis of the magnetisingcurve, is given in this paper.
