Transformer substation infrared monitoring method and device and computer readable storage medium

Abstract

The invention discloses a transformer substation infrared monitoring method and device and a computer readable storage medium. The monitoring method comprises the following steps: acquiring an original infrared image of a series compensation capacitor bank; performing de-noising processing on the original infrared image to obtain a first infrared image; performing enhancement processing on the first infrared image to obtain a second infrared image; and performing edge detection on the second infrared image to determine a fault position of the series compensation capacitor bank. A monitoring device realizes remote monitoring based on the visual Internet of Things, and performs real-time alarm on abnormal heating of equipment. Visual labels are marked on an abnormal heating area and an areawith high temperature, the temperature change condition is analyzed, and faults are prevented from happening and upgrading. The monitoring device can accurately monitor and locate an equipment temperature abnormal area in real time, continuously monitor an area with over-high temperature and give an early warning for faults, and provides reliable guarantee for abnormal monitoring of series compensation capacitor bank equipment.

Description

technical field [0001] The invention relates to the technical field of intelligent monitoring of electric power systems, in particular to a substation infrared monitoring method, device and computer-readable storage medium. Background technique [0002] The series-compensated capacitor bank is one of the key equipment in the UHV substation. Timely monitoring and diagnosing the potential failure of the series-compensated capacitor bank is of great significance to ensure the safety of the entire transmission line. The UHV series capacitor bank is arranged on a platform with a height of more than ten meters, and the equipment is densely packed, and the staff cannot directly see the operating conditions of the equipment. The series compensated capacitor bank has typical faults such as bulging, oil leakage, and heat generation. The AC UHV series compensated capacitor bank is large and densely distributed. Once a fault occurs, it is easy to cause equipment fires and cause group ex...

The UHV series capacitor bank is arranged on a platform with a height of more than ten meters, and the equipment is densely packed, and the staff cannot directly see the operating conditions of the equipment

The series compensated capacitor bank has typical faults such as bulging, oil leakage, and heat generation. The number of AC UHV series compensated capacitor banks is large and densely distributed. Once a fault occurs, it is easy to cause equipment fires and cause group explosions

[0003] In the prior art, a laser level measuring instrument is installed on the inspection trolley for the monitoring of the bulge. Such a monitoring method requires a complicated device, and it is necessary to set a fixed track for the inspection trolley. The failure rate is high, the monitoring is not timely, and the diagnosis is not good. Timely, if the potential safety hazards are not dealt with in time, it is likely to cause greater economic losses; for the monitoring of oil leakage and heat generation, wireless thermometers, infrared cameras and visible light cameras are used for serial monitoring, but this method is based on serial compensation of communication protocols Equipment monitoring and communication control technology cannot detect potential safety hazards in time, let alone accurately determine the location and geometric size of the fault
