A Voiceprint Recognition Method for Substation Fault Judgment

Abstract

The invention discloses a substation fault judgment voiceprint recognition method, which overcomes the problem in the prior art that the number of substations and the equipment in the substation are more and more difficult to judge equipment faults. First, a system model is established to store the common noise types in the substation. Store the waveform and voiceprint information of various noises in the system model, build multiple filters based on the known noise, and collect the noise information in the substation in real time. Pass the real-time collected noise information through the filter of the system model, if the filtered If the noise can be correlated with a pre-stored noise waveform, it is determined that the substation is faulty. The invention adopts the method of voiceprint recognition to obtain a conclusion by filtering the sound and then comparing the graphs of the waveforms.

Description

technical field [0001] The invention relates to the technical field of substation monitoring, in particular to a voiceprint recognition method for substation fault determination. Background technique [0002] In daily life, speech is a medium for transmitting information. The content of speech can be obtained from different speech, and the personal information of the speaker can also be confirmed through the unique characteristics of the speech. When the power equipment is running, it will also make its own voice like a human being. Experienced electric power masters can often judge whether there is a potential safety hazard in the equipment based on these voices. Stable operation is critical. With the development of power grid construction, the number of substations will increase, and it is unrealistic to completely rely on masters to judge equipment failures. There are many equipments in the substation, including transformers, switch cabinets, insulators, busbars, discon...

Problems solved by technology

[0003] The present invention aims to overcome the problem in the prior art that it is difficult to judge equipment faults due to the increasing number of substations and equipment in the substation, and provides a voiceprint recognition method for substation fault judgment. Above the sound, the fault sound is associated with the preset corresponding fault, and the type of fault is judged, which improves the accuracy of substation fault identification
