为了抑制高压直流系统中的谐波电流和电压,交流滤波器广泛应用于换流站中。通过对传统双调谐滤波器的研究,得出了一种阻尼式双调谐滤波器的设计方法。利用PSCAD/EMTDC进行仿真,表现了所提出方法在抑制谐波以及提高功率因数中的效果。
The AC filter is always needed in HVDC systerm to suppress harmonic currents and voltages.A design method of damped-typed double tuned filter is presented after the study of conventional double tuned filter.This design is simulated on the PSCAD/EMTDC and the results clearly show the effect of the method in suppressing harmonics and improving power factor.
