基于时频域结合的配电变压器谐波损耗计算
|
摘要
本文中作者提出了一种基于时频域结合的配电变压器谐波损耗计算模型,通过仿真分析和试验,研究了谐波电压与空载损耗、谐波电流与负载损耗、谐波电压叠加谐波电流与总损耗之间的关系。
Based on time-frequency domain combination, the harmonic loss calculation model for distribution transformers is proposed by the authors in this paper. Based on simulation analysis and experiment, the relationship between harmonic voltage and iron loss, harmonic current and copper loss, harmonic voltage superimposed harmonic current and total loss are researched.
