集成电路型正序分量和负序分量过滤器的设计

A new method for detecting the fundamental negative and positive sequence components as well as the harmonic components is developed in this paper.

提出了一种新的实时检测基波正序分量、基波负序分量和谐波分量的方法 ,该方法首先将三相瞬时值合成一个空间矢量 ,然后对所得矢量的实部和虚部分别进行滤波以滤去谐波分量。

By using the positive sequence component of voltage and current synchronously sampled at both terminals,the positive-sequence voltage of fault point can be deduced from both terminal based on uniform transmission line equations,then the fault location equation can be got.

基于分布参数模型,提出了一种不同电压等级的同杆并架多回线路故障测距方法:利用两端同步的电压和电流的正序分量,根据均匀传输线方程从线路两端分别推导出故障点处的正序电压,进而得出故障测距公式。
