摘要
提出一种利用暂态主频量的单端测距算法,并分别通过频域法和时域法的求解,得到故障距离。EMTP仿真结果表明,其测距的最大相对误差小于0.231%,平均测距误差小于20 m,能够满足实际工程需求。
This essay presents a single-ended ranging algorithm based on transient basic frequency components. The fault distances can be obtained by using the frequency domain and time domain methods to get relevant solutions. The EMTP simulation results show that the maximum relative error of the algorithm in ranging is less than 0.231% and the average error is less than 20 meters, so it can meet the requirements of practical engineering.
