对直流偏磁下产生的励磁电流各谐波成分进行理论分析和仿真验证。研究结果表明,换流变压器直流偏磁下的励磁电流中二次谐波占主要成分,二次谐波与注入直流电流呈线性关系,且其随直流电流的增长幅度要高于其他低次谐波。
對直流偏磁下產生的勵磁電流各諧波成分進行理論分析和倣真驗證。研究結果錶明,換流變壓器直流偏磁下的勵磁電流中二次諧波佔主要成分,二次諧波與註入直流電流呈線性關繫,且其隨直流電流的增長幅度要高于其他低次諧波。

This essay introduces the theoretical analysis and simulation study of the harmonic components of the field current under the condition of the DC magnetic biasing. The research result shows that there is mainly second har- monic in the field current under the condition of the DC magnetic biasing of the converter transformer, there is a lin- ear relation between the second harmonic and the injected DC, and the second harmonic grows faster than other low- order harmonic with the growing DC.
