摘要
半控双三相12脉冲整流器是一种谐波源,所产生的高频谐波对磁悬浮列车的安全稳定运行有很大的危害。将小波变换用于磁悬浮列车牵引供电系统的谐波分析,可将信号中的高频成分逐步分离,减少高频谐波成分对电力系统的污染,对实现磁悬浮列车牵引供电系统谐波信号的高分辨率检测具有很好的应用价值。
Semi-control double three-phase 12-pulse rectifier is a harmonic resource and its harmonics do great harm to the safe and stable movement of high-speed maglev. Wavelet transform was used to analyze the high frequency harmonics of traction power system of high-speed maglev. The high frequency harmonics of the signals could be separated and its pollution could be decreased while wavelet transform was used. It is of great value in realizing highdistinction measurement of traction power system of high-speed maglev.
