摘　　要：雷电冲击试验是耐压与绝缘试验中的重要项目,是判断电气设备是否满足高压工作要求的重要依据。为方便对冲击电压波形的参数进行定量调整,本文基于Simulink平台,建立雷电冲击电压发生器的仿真模型,并采用1600kV/80kJ雷电冲击电压发生器进行验证。实验证明:仿真波形与实际波形的电压峰值U_(m)、波前时间T_(1)与半峰值时间T_(2)之间的一致性误差未超过±3%,可快速、准确地调整冲击电压波形关键参数,提高日常实验效率,辅助实验设备的运维管理。Lightning shock test is an important item in voltage resistance and insulation test,and is an important basis for judging whether the electrical equipment meets the requirements of high voltage work.In order to facilitate the quantitative adjustment of the parameters of impulse voltage waveform,the simulation model of lightning impulse voltage generator is established based on Simulink platform,and compared with 1600kV/80kJ lightning impulse voltage generator.The experimental results show that the consistency error between the simulated waveform and the actual waveform′s voltage peak U_(m),wavefront time T_(1) and half-peak time T_(2) is less than±3%,which can quick-ly and accurately adjust the key parameters of the impulse voltage waveform,improve the efficiency of daily experi-ments,and assist the operation and maintenance management of experimental equipment.
