Problems solved by technology
And the movable monitoring device also has problems such as manual movement inconvenience.
[0004] Existing mobile partial discharge monitoring devices often only determine the equipment where the partial discharge source is located, and cannot accurately point out the specific location of the partial discharge source
This kind of mobile partial discharge monitoring device has low flexibility, and it is not easy to reach the vicinity of the partial discharge source through the automatic mobile platform for further monitoring
[0005] Most of the existing devices for further monitoring near the partial discharge source use ultrasonic monitoring method and pulse current method for monitoring, which have low sensitivity, poor anti-interference ability, low measurement frequency, narrow frequency band, and less information contained. defect

The invention relates to a substation partial discharge automatic monitoring and positioning method and system based on an inspection robot, and belongs to the field of smart power grids. The method is based on a system consisting of an inspection robot, an ultra-high frequency antenna array composed of four omnidirectional antennas, an alarm, a laser indicating lamp, a steering engine, a steppingmotor, an electronic compass, a gyroscope, a signal processing module, a signal acquisition module and a central processing unit. The robot is used for polling in a transformer substation; when a partial discharge signal is judged and monitored through an energy accumulation algorithm, the robot goes to the position of a partial discharge source; the pointing direction of the ultra-high frequencyantenna array fixed on the robot is automatically adjusted by utilizing the time difference of the ultra-high frequency signals received by the antenna array; and the partial discharge source is indicated, accurate monitoring and positioning of the partial discharge source of the transformer substation are realized, and partial discharge information is transmitted to a remote end through a wireless transmission module on the robot and is displayed on a display.
Description
technical field [0001] The invention belongs to the field of smart grids and relates to the technical field of insulation monitoring of high-voltage power equipment, in particular to an automatic monitoring and positioning method and system for substation partial discharge based on inspection robots. Background technique [0002] At present, the partial discharge monitoring and positioning of substation equipment at home and abroad are mainly carried out for specific single equipment such as circuit breakers and transformers, and the monitoring of the entire substation cannot be realized; [0003] The existing fixed partial discharge monitoring device needs to install a partial discharge monitoring device on each device, which is extremely expensive, and the use efficiency of the monitoring system is also low, and the maintenance workload of many online monitoring devices is also very large . This kind of fixed partial discharge monitoring device has a fixed position during...
