Unmanned Aerial Vehicles Transform Power Line Maintenance
In 2018, the energy company AltaiKrayEnergo introduced its first quadcopter to whirl above power lines. By then, an exhaustive electronic 3D map was already in place, pinpointing the geographical coordinates of each pylon. This data served as a foundation for groundbreaking tasks ahead.
During that period, various industries began to actively utilize drones. The energy sector, keen to innovate, embarked on trial runs using drones to detect power line defects. Maxim Pereverzev, the deputy CEO of AltaiKrayEnergo, detailed that traditionally, power lines were de-energized for inspection, risking power outages for entire communities connected to 10 kV lines. Now, drone technology has eliminated that requirement.
Equipping drones with high-resolution cameras and educating operators on navigation, the company cleared a path for these unmanned aircraft to fly autonomously to designated coordinates.
The Initial Outcome
To ascertain a pylon’s condition, the drone circumnavigates and photographs it from multiple angles, capturing every imperfection. Operators are tasked with uploading these images into a system where 13 engineers spanned across nine branches used to manually assess the condition, marking severe errors for immediate repair (indicated by red) and less critical issues for future attention (yellow).
First Neuro-Network Application
In light of the promising machine learning and AI technologies, the energy experts contemplated harnessing neural networks for defect detection. Consequently, they crafted the “Intelligent Diagnostic System for Energy Facilities” (IDES) and secured a grant from the Skolkovo Foundation for its development in 2021. The software evolved to identify multiple categories of defects; the neural network’s analytical speed outstripped traditional methods dramatically.
Prospects Moving Forward
Propelled by AI, diagnostics have become vastly quicker, with a single expert now managing the tasks once spread among 13 engineers. Two operators pilot a pair of drones to handle the inspections and documentation of power pylons. This leap in innovation has not only reduced emergency scenarios but also conserved funds allocated for defect detection, enhancing the overall reliability of the energy system.
AltaiKrayEnergo’s initiatives garnered attention at the III Scientific-Practical Conference on Digitalization in Belarus, earning commendations from the Ministry of Energy. Today, the company oversees over 205,000 pylons, extending more than 9,000 kilometers of transmission lines to over 350,000 energy consumers.
Important Questions and Answers:
– What are the key challenges associated with drone inspections in the energy sector?
Drone inspections in the energy sector can face logistical challenges such as dealing with remote or difficult terrain, legal and regulatory hurdles, the need for significant pilot training, and ensuring data security. Adapting to rapidly changing technology and integrating it into existing systems can be another substantial challenge. Moreover, there may be concerns about potential job displacements due to automation.
– What controversies are associated with the use of drones for power line inspections?
Privacy concerns and airspace regulations are two major controversies. Individuals and organizations are often wary of drones’ potential to infringe on privacy, as the cameras used for infrastructure inspection might inadvertently capture private property. Compliance with Federal Aviation Administration (FAA) regulations or country-specific regulations is required, which sometimes restricts drone operations.
Advantages:
– Efficiency and Safety: Drones provide a quicker and safer way of inspecting power lines than manual inspections, especially in hazardous or hard-to-reach areas.
– Cost Reduction: By employing drones, companies save on the costs associated with traditional inspection methods, which involve de-energizing lines, scaffolding, or sending out repair crews.
– Preventive Maintenance: Drones can aid in identifying potential issues before they become major problems, reducing the incidence of power outages and emergency repairs.
– Data Accuracy: High-resolution cameras and 3D mapping ensure precise data collection, improving the accuracy of diagnostics.
Disadvantages:
– Initial Investment: The initial cost for setting up a drone inspection system, including purchasing drones, training personnel, and developing software for data coordination, can be high.
– Regulatory Compliance: Complying with aviation regulations can be complex and may limit the use of drones in certain areas or at specific times.
– Data Management: Effective data management systems are needed to handle and analyze the large volumes of data collected during drone inspections.
– Technical Limitations: Drones have limitations regarding battery life, payload capacity, and flight range, which can affect their efficiency in extensive inspections.
