| 摘 要： | 有源滤波器是对于非线性负荷电流谐波抑制和无功补偿的重要装置,其中关键的环节就在于其能实时准确地检测谐波和无功电流。本文结合单相负荷谐波、无功电流检测与平衡变压器能够抑制负序条件,提出了2种能够不受左右供电臂负荷限制,能完全动态检测电气化铁道负序、无功与谐波的检测方法,并在MATLAB/SIMULINK下仿真证明该方法可以动态、准确地检测出牵引供电系统负序、谐波及无功电流,并实现三相平衡。

| Abstract: | The active power filter is an important method which compensates regarding the non-linearity load current harmonic suppression and the reactive power. The key link lies in real-time accurately examines the harmonic current and the reactive power current. This article unifies the single-phase load harmonic current and the reactive power current examination and the balance transformer can suppress sequence currents condition, proposed two kinds cannot be limited by left and the right power supply arms loads. ... |
