【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]:Under the condition of AC / DC mixed excitation, the analysis and verification of stray loss in large electromagnetic devices and how to effectively reduce the stray loss have attracted much attention in product analysis and design. The flat-wave reactor is one of the important electrical equipments in the (HVDC) of HVDC transmission system. When it works, it passes through large DC current and high harmonic current (AC / DC mixed excitation). In this paper, the effective and practical determination method of stray loss in magnetic conducting steel plate is studied systematically from two aspects of experiment and simulation analysis, and it is verified by the established international reference model. An engineering practical measure to accurately determine stray loss in the structure of electromagnetic equipment of flat-wave reactor by indirect processing method is put forward. The results obtained can provide a reference for electromagnetic design of products.
