摘　　要：为实现有效、准确地评估变压器油纸绝缘系统老化状态,在极化去极化电流法的基础上,结合扩展德拜模型,设计搭建了油纸绝缘测量系统,进行试验并求解得到去极化电流曲线,提出了一种基于鲸鱼优化算法(WOA)与Levenberg-Marquardt(LM)算法的融合算法进行油纸绝缘系统扩展德拜模型参数辨识,并建立了扩展德拜模型。与其他优化算法结果相比,所提算法求解精度高、收敛速度快,为实际场景中快速精确评估油纸绝缘设备绝缘老化状态奠定了基础。In order to effectively and accurately evaluate the aging state of oil-paper insulation system of transformer,the oil-paper insulation measurement system was designed and built based on the polarization and depolarization current method and combined with the extended Debye model.And then the depolarization current curve was obtained by test.A fusion algorithm based on whale optimization algorithm(WOA)and Levenberg-Marquardt(LM)algorithm was proposed to identify the parameters of the extended Debye model of oil-paper insulation system,and the extended Debye model was established.Compared with the results of other optimization algorithms,the proposed algorithm has high solution accuracy and fast convergence speed,which lays a foundation for the rapid and accurate assessment of insulation aging state of oil-paper insulation equipment in actual scenarios.
