Abstract:

基于晶闸管可控电抗器(TCRs)的谐波耦合矩阵模型,对TCRs的谐波产生特性进行了深入分析。TCRs的频域谐波耦合矩阵模型,以完全解析的公式将TCRs端口各次谐波电压和各次谐波电流之间的互耦合和自耦合关系直观地展示出来。通过对矩阵元素的物理意义和取值规律进行研究,分清了在TCRs谐波产生过程中的主要和次要影响因素,进而提出了TCRs的忽略谐波电压共轭影响的模型、解耦的模型和恒流源模型,给出了各简化模型的解析计算公式,并研究了触发延迟角对简化模型精度的影响。分析表明当触发延迟角小于70°时,简化模型具有较高的精度;当触发延迟角大于70°时,各简化模型都将引入不同程度的误差。研究结论可为工程应用中TCRs谐波源模型的合理选择提供理论参考。
