摘　　要：本文中作者提出了基于Tikhonov正则化的变压器在线监测方法,通过变压器一次侧与二次侧的电气信息,可快速准确地辨识变压器绕组电阻、电感参数,从而确定变压器绕组状况。Based on Tikhonov regularization, a transformer on-line monitoring method is presented by the authors in this paper. The electrical information of the primary and secondary sides of the transformer can be used to quickly and accurately identify the resistance and inductance parameters of the transformer winding,so as to determine the winding status.
