摘　　要：随着电力行业的迅速发展,其对供电质量的要求更趋严格,而供电网中存在的谐波极大地影响着有轨电车和电气设备的供电质量和安全,因此,谐波检测和抑制受到越来越多的关注。其中,瞬时功率理论作为检测谐波电流方法的指导理论,在诸多相关检测方法中应用最广,在深入研究该理论的背景下,利用MATLAB/Simulink对其不同的检测方法进行了仿真研究,实现检测和分离出三相电流基波分量和谐波分量,仿真实验结果证明了检测方法的有效性。With the rapiddevelopment of power industry,requirements on power supply quality tend to be more rigid.However,harmonics in power grid greatly affect the power supply quality and safety of tram and electrical equipment.Therefore,harmonic detection and suppression are drawing more and more attention.The instantaneous power theory,as the guiding theory for harmonic current detection,is most widely used in related detection methods.In the context of in-depth theory study,MATLAB/Simulink was employed to carry out simulation application research on the different detection methods,and a preferable harmonic current detection method was concluded to detect and separate the fundamental and harmonic components of the three-phase current.The results of simulation experiments proved the effectiveness of the detection method.
