Abstract

The invention discloses an analysis method for efficient transmission and filtering of a grounding fault recording file. The analysis method comprises the steps of collecting high-fidelity and low-error recording information through using a high-precision collection unit, carrying out the recording data transmission optimization of the collected recording information through a network through a collection unit, transmitting the data to a remote main station, and carrying out interference wave filtering on the sent waveform and the corresponding topological relation and then carrying out grounding fault positioning by means of the remote master station. On the basis of good waveform transmission and interference wave filtering, reliable data for research and judgment are provided, and the accuracy of ground fault judgment is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of small current grounding faults, and more specifically relates to an analysis method for efficient transmission and filtering of grounding fault recording files. Background technique [0002] Power supply reliability is the fundamental index to measure the performance of the power supply system, so locating faults, quickly solving distribution network faults, and shortening the number and duration of power outages are fundamental to improving power supply reliability. In distribution network faults, the proportion of ground faults is high, and the fault current is small. The vast majority of faults in the actual distribution network are single-phase ground faults, accounting for about 60% to 80% of the total faults; followed by two-phase faults (including short-circuit to ground), about 15%; and the proportion of three-phase faults is the smallest , less than 5%. Therefore, solving the small current sing...
