摘　　要：雷电冲击电压放电试验用以检测电力设备在运行过程中承受暂时过电压及雷电过电压时的绝缘水平,是系统中常见的设备绝缘测试方法。传统的测试方法涉及的设备元器件多,搭建试验平台较为繁琐,且参数计算与测试过程用时较长,因此测试效率较低。本论文研究了一种基于Simulink的冲击电压放电试验仿真系统,该系统首先对试验设备进行建模,通过仿真的方法计算合理的试验参数,运行得出理想的试验结果,再以此作为依据在测试平台上进行试验。采用冲击电压放电试验仿真系统进行雷电冲击电压放电试验,可大幅缩短试验时间,提高测试效率。Lightning impulse voltage discharge test is a common method for testing the insulation level of power equipment under temporary overvoltage and lightning overvoltage during operation.The traditional test method involves many equipment and components,and the test platform is more complicated,and the parameter calculation and test process take a long time,so the test efficiency is low.This paper studies a simulation system of impulse voltage discharge test based on Simulink.Firstly,the system models the test equipment,calculates reasonable test parameters by simulation method,and runs to get ideal test results,and then carries out the test on the test platform.The lightning impulse voltage discharge test is carried out by using the impulse voltage discharge test simulation system,which can greatly shorten the test time and improve the test efficiency.
