新型换流变压器绕组振动特性的ANSYS分析

摘要

利用ANSYS有限元软件仿真求得新型换流变压器绕组振动模态和绕组振动位移数据.经过Matlab离散数据快速傅里叶变换(FFT)分析波形得到绕组振动频率成分.针对新型换流变压器阀侧绕组、滤波绕组、网侧绕组振动频谱分析,得出绕组振动频率与绕组电流频率存在某种关系的特性.%Vibration modal and waveform of new converter transformer were simulated by ANSYS.Vibration frequency was analyzed through FFT.According to vibration frequency spectrum of valve side winding,filtering winding and line winding,a characteristics relationship in frequency of winding vibration and current was obtained.
