Application research of the voiceprint imaging technology in substation patrol

Abstract

In order to make full use of the noise information of substation power equipment and to deeply explore the value of noise, a voiceprint imaging technology in substation patrol was proposed in this paper which replace the the noise monitoring by human ear. The basic principle, algorithm, array selection and other technical details of the voiceprint imaging technology were introduced in detail. The effectiveness of the technical measure in substation patrol was proved by an application case. The voiceprint imaging technology in substation patrol is safe, fast and accurate. It fills the technical gap of power equipment noise patrol and greatly improves the efficiency of substation patrol.
