保护电位判据 Protective potential criteria
This algorithm uses the value of fault voltage and fault current measured from one side of the line to estimate the fault voltage of the other side. The ratio of the estimated to the measured value constitutes the protection criterion.
该算法利用线路一侧电压、电流故障分量的测量值估算另一侧的电压故障分量,以估算值与测量值的比值构成保护判据。
