摘要交直流混合激励条件下,大型电磁装置构件中杂散损耗的分析与验证,以及如何有效降低杂散损耗在产品分析与设计中备受关注。平波电抗器是高压直流输电系统（HVDC）中重要的电气装备之一,其工作时绕组中通过较大的直流电流以及高次谐波电流（交直流混合激励）。本文从实验与仿真分析两方面系统地研究交直流混合激励时,导磁钢板中杂散损耗有效、实用的确定方法,并通过已建立的国际基准模型进行相关验证。提出采用间接处理方法准确确定平波电抗器类电磁装备结构件中杂散损耗的工程实用措施,所得结果可为产品电磁设计提供参考。

Abstract：The modeling and reduction of the stray-field loss under ac-dc hybrid excitations have paid increasing attention for the analysis and design of large electromagnetic devices. The smoothing reactor, an essential electrical equipment of the HVDC system, experiences an ac-dc hybrid excitation. This paper aims to investigate the effective and practical approaches, which can determine the stray-field losses in components under both single ac excitation and ac-dc hybrid excitation. The proposals based on the benchmark models are verified. An indirectly method is presented to accurately determine the stray field loss in the magnetic components of smoothing reactor and other magnetic devices. The results will be useful to the electro-magnetic design of the product.

Key words： Electro-magnetic components hybrid excitation benchmarking model smoothing reactor stray-field loss
