电力谐波分析中,为了最大程度地抑制或消除频谱混叠对动态测控系统的影响,必须利用抗混叠滤波器。设计抗混叠滤波器时不仅要满足采样定理的要求还必须考虑转换器的转换精度从系统设计的角度综合考虑才能得到符合要求的抗混叠滤波器。
In power harmonic analysis, in order to minimize or eliminate the influence of spectral aliasing on the dynamic monitoring and control system, anti-aliasing filter must be used. Anti-alias filter design not only to meet the requirements of the sampling theorem must also consider the converter conversion accuracy from the system design point of view to get the anti-aliasing filter to meet the requirements.
