摘要 电力电子器件的应用会对电网造成谐波干扰。变频器是典型的电力电子器件。石灰双膛竖窑在生产过程中有多台、大功率的电机变频运行,对所连接的母线造成谐波污染。通过ETAP软件,搭建了双膛竖窑典型电气供电系统图。并且用谐波分析功能,获得了低压母线总的电压畸变率和各次谐波含量的准确频谱。 It is well known that the electric component would cause harmonic interference to electric grid.Frequency converter is a typical electric component.A number of high capacity motors controlled by frequency converter are used in double shaft kiln,which generate harmonic interference to busbars.To avoid the problem,a typical systematic diagram for power supply of double shaft kiln is established by ETAP software plus the function of harmonic analysis,which can help us get total voltage distortion rate of L. T. busbar and accurate frequency spectrums for different harmonic contents.
