Dynamic adjustment method for infrared temperature measuring period of transformer station equipment

Abstract

The invention discloses a dynamic adjustment method for an infrared temperature measuring period of transformer station equipment and belongs to the technical field of electric power systems. According to the invention, an expert knowledge rule base is created according to the adjustment content of the infrared temperature measuring period; the percentage of the load and schedule load, as well as the percentage of the load and minimal interval carrying capacity where the load is positioned, can be computed; a mathematical expression of the expert knowledge rule base is built; and an inference machine is adopted to perform inference for the mathematical expression of the expert knowledge rule base, thereby, obtaining the temperature measuring period adjustment result. According to the method provided by the invention, the infrared temperature measuring period can be automatically adjusted according to variation of the scheduling load, thereby timely discovering hot potential hazard of the equipment, and providing effective means for ensuring the safe and steady operation of the electric power equipment.

Description

technical field [0001] The invention belongs to the technical field of power systems, and in particular relates to a method for dynamically adjusting the infrared temperature measurement cycle of substation equipment. Background technique [0002] Thermal faults in power systems are one of the main faults that cause unplanned power outages in power systems. How to effectively and accurately detect and prevent thermal faults and hidden dangers in power systems has become one of the important issues in the safe operation of power systems. At present, infrared temperature measurement technology is widely used in the detection and prevention of thermal hidden dangers and thermal faults in power systems due to its long-distance, non-stop power supply, non-contact, non-sampling, non-disintegration, and ability to effectively reduce unplanned power outages. The thermal failure of the power system is largely caused by the excessive power load. How to effectively combine the dispatch...

Problems solved by technology

At this stage, the infrared temperature measurement and detection of power transmission and transformation equipment basically depends on the regular periodic inspection, which is one of many inspection items in the regular periodic inspection. It is difficult to dynamically adjust the inspection cycle according to the load changes of the equipment, thus missing the opportunity to prevent failures best time
