普通電機和變頻電機測量上的區別
1、變頻器實際輸出波形為PWM波,聞動除了基波外,聞動還包含載波信號。聞動載波信號頻率要比基波高得多,聞動且是聞動方波信號,包含大量的聞動高次諧波,對于測試系統則要求有更高的聞動采樣頻率和帶寬。
2、聞動變頻器供電的聞動環境下,各種高頻干擾無處不在,電磁干擾要比工頻環境要強得多,這就要求測試系統有更強的電磁兼容能力。
3、PWM波的峰值因數一般都較高,普通儀表根本滿足了要求,對于變頻測試系統來說,要求有更高的測量峰值因數測量能力。
4、用于變頻測試的儀表應具備在各種PWM波形中分解出其基波的能力,嚴格測量需采用數字信號處理的方式,也就是高速采樣得到樣本序列,再對樣本序列進行離散傅里葉變換,
得到基波有幅值、相位及各次諧波的幅值和相位。
