Problems solved by technology

For a long time, due to the low accuracy of line selection and positioning, ground fault location in various places is still mainly based on manual test pull line selection and section selection
At present, the shortcomings of small current ground fault detection are that a single line selection method cannot adapt to various systems; the display of ground faults is simplistic, and the reliability of manual judgment after the system analyzes the fault point is also different due to differences in personal qualities.

Abstract

The invention relates to a method for judging earth fault information visual configuration. The method for judging the earth fault information visual configuration comprises a step S1 of determining a standard wave recording file and power topological information; a step S2 of obtaining the standard wave recording file; a step S3 of establishing the power topological information; a step S4 of analyzing the wave recording file; a step S5 of synthesizing a fault locating result by means of a plurality of algorithms by employing a unified input and different output manner on the wave recording file; and a step S6 of analyzing a locating statement. According to the invention, the waveform comparison efficiency is greatly improved, and the labor workload is greatly reduced.

Description

technical field The invention relates to the field of electrical engineering, in particular to a visual configuration judgment method for ground fault information. Background technique With the development of the electricity market and economic construction, the reliability of distribution network power supply has become an important issue for power supply enterprises. In order to improve the power supply capacity and ensure the quality of power supply, distribution network automation has become a very urgent task. The 10kV distribution network mostly adopts the method of ungrounding the neutral point or grounding through the arc suppression coil, which is called a small current grounding system. A large number of statistics show that single-phase (small current) ground fault is the most important fault form of 10kV distribution lines, accounting for about 2 / 3 of the total number of faults. The sensitivity, selectivity and reliability of the ground fault line selection and ...
