VSI终端输出电压是通过将平衡的三相系统表示为单相RMS等效模型来确定的。在这种情况下,电网电压被认为是=Vgrid=230Vrms∠0∘串联电感器和电阻器的阻抗为Z=R+2πfL,其中f对应于50Hz的标称电网频率。VSI端子处产生这种电流所需的平均电压输出为Vinv=Vgrid+Z·Irated,其中Vinv是复数RMS值。 注意,每个开关周期(Ts...
线电压指的是供电线间的电压(The voltage across the supply line)即;线电流指的是连接负载与电源间导体上的电流(The current flowing in the line between supply and load)。 【小知识:在工程学书籍文献以及实际应用中,三相系统/设备的“额定电压”在未特殊说明的情况下指的是线电压的均方根值(RMS line volt...
Under the conditions of both the ideal sinusoidal wave voltage and practical non-sinusoidal wave voltage, the said stabilizer can ensure the stabilizing accuracy of output voltage in true effective value.张树华
I want to use RMS of three-phase voltage as parameter for prediction. I would like to know how to compute the RMS of voltage of a 3-phase motor ? In fact, I have a 1000 samples for each voltage phase ( http://www.mediafire.com/?savomeetkb7frwa ) and I found a formula to ...
