complex harmonic current 中文意思是什麼
complex harmonic current
解釋
復諧電流-
Fault feature in stator current is extracted by singularity detection of signals with half - complex wavelet transform and it can be helpful to the real - time detection of motor fault. harmonics caused by the fault of motor is detected accurately with real - time harmonics cancellation method. steady state current and starting current in stator are analyzed with real - time harmonics cancellation method and the improved harmonic wavelet separately, after that the feature component of rotor fault can be detected successfully
採用半復小波變換對電機定子電流進行奇異性檢測,提取故障突變信號,有助於電機故障的實時診斷;通過實時諧波消去法檢測定子故障引起的高次諧波電流;採用改進的實時諧波消去法精確提取電機穩態電流中的轉子斷條故障特徵分量;為了進一步提高轉子斷條故障診斷精度,利用改進的諧波小波對電機起動電流進行時頻分析,提取轉子斷條故障特徵。
