摘　　要：评述了变压器类设备在雷电过电压和特快速暂态过电压(VFTO)作用下基于黑盒原理的无源高频宏模型(Macromodel)的建立方法、研究现状和存在的问题。首先给出了宏模型的定义和基于黑盒原理的宏模型的建立方法,然后就该方法在"网络函数获取"、"无源电路实现"和"模型阶数缩减(Model Order-Reduction)"等3个方面进行了讨论,最后给出了本课题组现阶段的部分研究成果,并指明了研究方向。The method based on black box principle was introduced to setup the high frequency macro circuit model for transformers under the lightning overvohage and VFTO as well as it＇s research status and existing problems. The paper first gives the definition of macromodel and it ＇s established method based on Black box principle, and then the existing problems of this method on three aspects is discussed ： the access of the network function, the passive circuit realization and the model order-reduction. Finally, the research results at current stage by Fund Task Force are given, and the direction of the study was indicated.
