摘要:

以某换流站内的双调谐滤波器为例,通过Matlab软件仿真计算出滤波器在不同抽头组合方式下的调谐频率,以及在此频率下的阻抗和相位,得到最满足设计要求的抽头组合,利用现场的调谐试验数据来验证仿真计算的正确性。

Abstract:

Taking the doubletuned filter in a converter station as example, using the Matlab software simulation, the tuning frequencies of the filter under different combination of the filter taps and the impedances and phases under the frequencies were calculated. The tap combination of the filter, which can satisfy the design requirement best, was obtained. The correctness of the simulation computation was proved by the field tuning experiment data.
