摘要
对比有源滤波器和无源滤波器的优缺点后,确定了车载谐波治理装置的设计方案。分析车载谐波治理装置的工作原理,从理论上推导电流无功分量和谐波分量的检测方法,并介绍了三态滞环调制策略的基本原理和实现方法。MATLAB仿真和地面试验结果表明,共一个牵引绕组的有源+无源车载谐波治理装置,可以有效降低机车输入电流的谐波含量,提升电流品质。
By contrasting the advantages and disadvantages between the passive filters and APF （active power filters）, the scheme of the harmonic restraining devices on the locomotive was confirmed. The working principle of the harmonic restraining devices was analyzed, and detection method of the reactive component and harmonic component of the current in theory was derived, focused on the principle and designing method of the three-level hysteresis control strategy. The results of MATLAB simulation and experimentation showed that the harmonic restraining devices composition of passive filter and APF on one traction winding could significantly restrain the harmonics current and improve the current quality.
