摘　　要：通过建立HVDC换流站的调制分析模型,详细推导了换流站交直流侧间的频率变换关系,并基于互调理论,详细分析了两侧交流系统间的相互影响,从而得到中间直流连接环节的频率特征。然后,利用调制规则,很好地揭示了两侧交流系统的间谐波的产生过程。Based on the modulation model erected in this paper for the converter in the HVDC system, the frequency transform rules between the ac and dc sides of the converter are deduced, and the interaction between the two ac systems is analyzed in detail with the intermodulation theory, getting hold of the frequency characteristic of the dc side. Then, the generation course of the harmonic and interharmonics are revealed by using the modulation rules,
