Gaoya dianqi, 2019 局部简化建模法即在不影响计算结果精度的要求下,在对实物进行建模时适当地做一些简化处理,对所关心的部件进行精细建模,而对其余部件进行简化建模。为验证局部简化建模法的有效性,文中基于TEAM Problem 21基准族中的P21a-2,P210-B模型,进行了详细地实验研究与仿真分析。重点考察了不同激励下采用局部简化建模法对变压器结构件（如变压器油箱）中杂散损耗、漏磁通密度计算值与测量值之间的对应关系。计算值与测量值具有较好的一致性,从而验证了局部简化建模法的工程适用性。在计算机资源有限的情况下 ...

Gaoya dianqiMMC子模块内母排杂散电感影响IGCT和二极管关断性能。在分析子模块功率器件开关行为基础上，基于仿真计算，分析了IGCT-MMC子模块内各支路母排杂散电感对IGCT和二极管器件关断特性的影响。对比双脉冲试验和仿真计算结果，验证了仿真模型和分析结论的有效性。结果表明，当母排杂散电感，特别是当主换流回路杂散电感较大时，将显著提高IGCT和二极管的关断过冲电压，以及关断峰值功率和损耗。研究结果可为基于IGCT的MMC换流器优化设计提供参考。
