“…For nearly 30 years, domestic and foreign scholars proposed many different criterions [3][4][5][6][7][8][9][10][11][12][13][14] .This paper proposed a new method of using frequency and amplitude of fault phase recovery voltage to judge single-phase fault based on the ESPRIT algorithm. EMTP simulation is carried out on 500 kV transmission line, and MATLAB was used to validate data.…”

The recovery voltage of fault phase includes frequency component and free oscillation component when single-phase grounding transient fault occurs, and only fundamental frequency component when permanent grounding fault occurs. In order to distinguish the transient fault and permanent fault, a new criterion based on Estimation of Signal Parameters via Rotational Invariance Techniques (ESPRIT) was proposed in this paper. ESPRIT algorithm based on subspace rotational invariance techniques to estimate the signal parameters can accurately estimate the frequency and amplitude of the signal. When transient fault occurs, there are two spectral lines of free oscillation component and fundamental frequency component, while when permanent fault occurs, only a spectral line of the fundamental frequency component. The simulation results show that ESPRIT algorithm can accurately estimate the frequency and amplitude of the signals, and the proposed criterion can effectively distinguish between the transient fault and the permanent fault.

In this paper a novel method of ATP (Alternative Transients Program) simulation for single-pole auto-reclosing is introduced. This paper presents an investigation of single-pole auto-reclosing on HV transmission lines. By simulating real trapped charge, overvoltage profile is monitored. Most of the faults on HV transmission lines are single-pole to ground. In order to have a general overview of single-pole auto-reclosing and calculating overvoltages simulation should be performed. Using ATP software, single-pole auto-reclosing on two real 400 kV transmission lines is simulated and the results are discussed. Details of system modeling are outlined. The simulation method and modeling of a real single-pole auto-reclosing by ATP is presented in detail. Effects of transmission line length as well as number of circuits are analyzed. Effects of reclosing time on single-pole switching overvoltages are outlined. Differences between single-pole auto-reclosing at different phases due to position of conductors are also presented.

This paper presents a single-phase auto-reclose study of a 1000 kV AC transmission line. The technology of auto-reclose has been widely used on the transmission lines in our country. The purpose is to make the fault line re-run after the temporary fault elimination. As most of the faults are transient in nature, the auto-reclose can greatly improve the reliability of the electricity and the stability of the power system, running side by side. The setting time of the conventional single-phase auto-reclose is determined by a fixed value, when the single-phase opens, auto-reclose recloses at the fixed-time regardless of the fault existence or not, as well as the secondary arc current. In this paper, the issue is given a reasonable solution. According to the arc eliminating time, the dynamic reclosing time is determined.
