摘要
论述了高压直流系统直流滤波器设计的原则和具体流程,并以双调谐直流滤波器设计为例,研究了一种适用于工程实际的直流滤波器设计方法,推导了双调谐滤波器与两个单调谐滤波器等效的数学表达式。通过调整两个等效单调谐直流滤波器的参数,进而设计出满足要求的双调谐直流滤波器。根据该设计方法,可以方便地调整双调谐直流滤波器的参数,并能保持双调谐滤波器的主电容值和调谐次数不变,节省了直流滤波器设计时间,提高了效率。最后,通过一个计算实例,验证了本文所述设计方法的有效性。
The design principles and specific process of dc filters in HVDC system were discussed in the paper. Taking the double-tuned dc filter as an example, a design method which is applicable to engineering practice was proposed for dc filter, and mathematical expressions were deduced to prove that double-tuned filter is equivalent to two single-tuned filters. By adjusting the parameters of the two equivalent single-tuned dc filter, the double-tuned filter as required was designed. According this design method, it is easy to adjust the parameters of the double-tuned dc filter, maintain the capacitor＇s value and the aming frequency of the filter, saving time and raising efficiency. Lastly, the effectiveness of this design method was proved by an instance.
