| description | The invention discloses a sampling frequency dynamic evaluation and selection method for a capacitor of a transformer substation. According to the method, a hardware frequency measuring circuit is used to perform analog low-pass filtering of a line voltage, and the harmonic interference to a zero-crossing point is removed in data processing so as to realize the high-precision acquisition of the real-time frequency and frequency tracking sampling and guarantee the precision of the harmonic analysis.
本发明公开了种变电站电容器采样频率动态评估和选取方法，采用硬件测频电路对线电压进行模拟低通滤波，并在数据处理上去除谐波对过零点的干扰，实现实时频率的高精度获取与频率跟踪采样，保证谐波分析的精度。 |
