摘要：
A concept named 'steady process in transient condition' is proposed for transmission line based on the transient expression of electromagnetic traveling wave. Considering the impact of distributed parameters and the characteristics of electro-magnetic wave, the transmission line model is built. Wave impedance factor is defined with line voltage fluctuation. The voltage equation is derived and the former is researched for complex domain projection, which is the improvement of orthogonal projection. And the voltage is approached exactly. The fault location function has been built up which can be used to confirm the fault position with effective measurement of voltage. The impedance factor is studied on variety, and the location result is more closely approximated to real situation. Without convolution, the efficiency and accuracy of this method has been proved. And the edge effect caused by orthogonal scaling function is solved. Complex domain analysis cannot be affected by step, and the adaptive calculation for the sampling frequency through simulation and analysis.
