Description

Diagnostic apparatus for power facilities The present invention relates to a power facility diagnostic device that monitors power facilities and diagnoses their condition using an unmanned aerial vehicle. Energy generated from power generation facilities is supplied to power demand centers through multiple power facilities, such as transmission lines, substations, and transformers. Power facilities are not only located within specific facilities or buildings, but are also distributed over wide areas outdoors, such as transmission towers and utility poles, and can be installed in hard-to-reach locations such as mountainous areas as well as flat land. Since transmission lines, transmission towers, and utility poles are exposed outdoors, there is a possibility of damage caused by natural disasters such as lightning strikes or typhoons; additionally, power facilities that have been installed for a long time may be damaged due to aging. Accordingly, these power facilities need to be inspected regularly and their condition managed. Traditionally, regular inspections were conducted using manpower; however, due to their distribution over a wide area, these inspections are time-consuming and require a large workforce. In particular, when facilities are installed in hard-to-access locations, such as mountainous areas, it is difficult to accurately inspect their condition. Furthermore, caution is required when personnel climb transmission towers directly due to the risk of accidents, such as falls or electric shocks. Although safety training is being conducted for workers to address these issues, its effectiveness remains insufficient. Accordingly, there is a growing trend to apply methods that acquire data from power facilities and remotely diagnose anomalies online as a means to effectively monitor and manage power equipment. However, access to power facilities located in mountainous areas remains limited, and there are issues where anomalies that are difficult to identify solely through measured data cannot be detected. For power facilities that are difficult to access, a method is being applied to diagnose abnormalities by using unmanned aerial vehicles, such as drones, to film the facilities. As a related technology, there is Korean Published Patent No. 10-2020-0009310, "Power Equipment Monitoring Device and Method." However, there is a problem of low diagnostic efficiency because the data that can be acquired is limited due to the limitations on the devices that can be mounted on the unmanned aerial vehicle, and the detectable failures vary by equipment.
