Abstract

The invention discloses a GIS local discharging detecting system and method based on sound-electricity integration sensor,comprising sound-electricity integration sensor, BP neural network fusion module, DS decision module and display module; the sound-electricity integration sensor is used for simultaneous detection of ultrasonic wave and ultra-high frequency signal generated from local discharging ; BP neural network fusion module filters and fuses the discharging information detected by sound-electricity integration sensor and transmits such information to DS decision module;according to the obtained discharging information, the DS decision module uses the D-S evidence theory to perform the decision fusion for fault type determination results and transmits the decision fusion to display module; the display module is used for display after analysis and processing of obtained data. The system and method are used for GIS local discharging detection by new sound-electricity integration sensor and detecting whether local positioning is performed while local discharging occurs.

Description

technical field [0001] The invention relates to the fields of electronic technology and control, in particular to a GIS partial discharge detection system and method based on an acoustic-electric integrated sensor. Background technique [0002] With the development mode of condition-based maintenance of power equipment and the development plan of UHV power grid, two separate electromagnetic wave and ultrasonic sensors are mostly used in traditional partial discharge acoustic-electric joint positioning. A new type of acoustic-electric integrated sensor uses a The sensor can obtain the acoustic-electric signal and the time difference of the acoustic-electric signal at the same time, thereby reducing the number of sensors required for partial discharge detection and positioning, and bringing convenience to partial discharge on-site detection and experiments. The sensor will make up for the shortcomings of the current 1000KV GIS partial discharge online monitoring method under t...
