Инновации с помощью компьютерного зрения и искусственного интеллекта в энергетическом секторе

The energy sector powers life as we know it, providing electricity for our homes, energy for industries, and the foundation for digital connectivity. It’s the invisible thread that keeps the wheels of society turning every day. 

As the world grapples with environmental concerns over fossil fuel consumption and aims to achieve net-zero carbon emissions, the focus has shifted toward sustainable energy solutions. However, while developing new energy sources is important, there’s also significant work being done to improve current energy systems and make them more efficient, reliable, and environmentally friendly.

Traditional methods of electricity generation and energy operations are slowly being integrated with advanced technologies like artificial intelligence (AI). Specifically, computer vision - the use of AI to interpret and analyze visual data - is playing a pivotal role in addressing challenges within the electrical sector.

Computer vision is changing the way electrical energy systems are monitored, maintained, and optimized. Let’s take a closer look at how this technology is being applied in the energy sector.

Understanding the Electrical Sector

Before we dive into the applications of computer vision in the electrical sector, it’s important to understand why these applications matter and who they impact.

Electricity production is a key part of the energy sector, and it involves four main steps: generation, transmission, distribution, and consumption. It starts with electricity being generated at power plants, which can use resources like fossil fuels, nuclear energy, or renewable sources such as wind, solar, and hydropower. The generated electricity is then transmitted over long distances through high-voltage power lines. Once it reaches high-voltage stations, it's distributed through substations and then delivered to homes, businesses, and industries via lower-voltage lines.

Here are the main stakeholders in the electricity production system:

• Utility companies: These are the companies that produce electricity in power plants and transmit it to consumers. They are responsible for maintaining infrastructure and ensuring a consistent supply.
• Grid Operators: They manage the electrical grid and monitor the balance between electricity supply and demand. These entities also oversee grid stability, prevent outages, and integrate renewable energy sources.

• Regulators: Regulatory bodies, mostly the government, enforce policies and rules for grid operators. They ensure compliance with safety, environmental, and economic standards and protect consumer interests.
• End-users: These are the consumers, such as households, industries, and businesses, who use electricity. 

Core Challenges in the Electrical Sector

The electrical sector faces several major concerns on a daily basis. Many electrical systems rely on aging infrastructure that wasn’t designed to handle today’s energy demands, leading to inefficiencies and a higher risk of failures like breakages in power lines. Maintenance is often reactive rather than proactive, which can result in costly downtime and unexpected issues. On top of that, outdated grid systems struggle to adapt to changing energy needs efficiently. Tackling these issues is a crucial part of creating a stable and dependable energy system for the future.

The Role of Computer Vision in the Electrical Sector

Computer vision is a subfield of AI that helps machines see and understand visual information from the world around them, similar to how humans do. A computer vision model can be trained to identify objects and patterns in images and videos to make informed decisions. 

In the electrical sector, Vision AI models like Ultralytics YOLO11 can be used to check for damages in voltage lines, inspect delicate parts in transformers, monitor circuits in real-time, and work in hazardous places like high-voltage and remote areas.

Applications of Computer Vision in the Electrical Sector

Computer vision innovations can come in handy for various purposes in the electrical sector, including inspection, monitoring, and management. Let’s take a closer look at some of the real-time use cases of computer vision models in the energy industry.

Drone Inspections

Computer vision-enabled ai drones equipped with high-resolution cameras can inspect power lines, transmission towers, solar farms, and other electrical infrastructure. The process typically involves either human-controlled or autonomous drones capturing images and videos of power lines in a specified area, which are then analyzed by computer vision models. 

Models, such as YOLO11, that support techniques like object detection and instance segmentation can be used to identify various issues. These include cracks, corrosion, vegetation encroachment, human interference near power lines, and equipment damage. This AI-driven approach speeds up the inspection process. It also improves safety by reducing the need for human workers to perform hazardous tasks, such as climbing towers or working in high-voltage zones.

A great example of this is Jiaozuo, a city in China, where drones are being used to improve the safety of the state grid's transmission lines. Human-controlled drones patrol the transmission lines to identify potential damages. Using drones, they have inspected 114 electrical lines and identified and resolved two hidden damages efficiently.

Substation Monitoring

Surveillance systems integrated with computer vision can monitor power stations for anomalies such as transformer overheating, circuit breakers, oil leakages, and equipment failures. If you look under the hood of such systems, you can usually find a custom-trained computer vision model. 

For example, by training a custom YOLO11 model on a diverse dataset of images capturing various equipment anomalies, like the ones listed above, we can create a robust system for automated anomaly detection. The trained YOLO11 model can be used to recognize specific patterns and deviations from normal working conditions. By using innovations like YOLO11, we can improve operational efficiency in power stations, eliminate workplace accidents, and make the workplace safer.

Nowadays, we are seeing an increase in these types of cutting-edge innovations. For instance, an AI-powered robotic dog named Sparky was used to explore AI-driven substation inspection in Connecticut. Sparky is integrated with computer vision and AI to be able to read and monitor voltage gauges, record thermal images, and detect damage to the equipment. It features a high-resolution camera with 30x zoom, an infrared camera, and an acoustic sensor to read sound signatures.

Smart Grid Surveillance

Computer vision models can also be leveraged with respect to smart grid systems to monitor power flow, identify bottlenecks, and detect potential vulnerabilities. Combined with other AI technologies, such as Internet of Things (IoT) sensors and data analytics, computer vision systems can enhance grid surveillance. 

Particularly, when paired with infrared imaging technology, computer vision models can capture heat signatures. Infrared imaging is a technique that captures images of objects based on their heat emission. It uses thermal cameras operating in the infrared spectrum to detect temperature variations that are invisible to the naked eye. This technology is helpful when it comes to identifying hotspots, which could indicate overheating, friction, or electrical faults in equipment.

In the electrical sector, infrared imaging is especially valuable for detecting issues such as overheating transformers, circuit breakers, and power lines. An infrared camera with computer vision capabilities can monitor utility poles in real time and look for sudden spikes in temperature. If a camera detects any unusual temperature changes, it can alert a maintenance team. The maintenance team can then investigate the issue and take necessary action, preventing potential outages and safety hazards.

Pros and Cons of Computer Vision in the Energy Sector

The electrical sector can benefit in many ways from using computer vision applications. Here are a few examples: 

• Cost Savings: By implementing vision-based solutions, labor costs can be reduced, especially labor costs associated with tasks like in-line inspections, which are time-consuming and hazardous. 
• Data-Driven Decision Making: Insights gathered from vision models can be combined with historical data to make informed decisions.
• Scalability: Computer vision models are flexible and can be implemented at any scale. They can easily be scaled up from a small area to a larger one, or down from a large area to a smaller one, without requiring major changes.

On the other hand, implementing computer vision systems comes with its limitations. Some of these concerns are mentioned below:

• High Initial Cost: Deploying computer vision systems, including drones, cameras, and AI infrastructure, can be expensive. For small-scale industries, investing a huge sum of money in new technology can be a significant challenge.
• Data Privacy & Security: Vision AI systems often involve the collection and processing of sensitive data, raising concerns about privacy and security.
• Environmental Limitations: The quality of visual data in computer vision inspections can be affected by factors like lighting, weather, and camera calibration. Adverse weather, such as fog, rain, or snow, can make these inspections less effective, especially outdoors.

The Future of Power

Computer vision is a reliable tool for tackling the complex challenges of the electrical sector. By automating visual inspections, analyzing large amounts of data, and enabling real-time monitoring, AI-powered solutions can play an essential role in meeting today’s energy demands. 

For instance, computer vision can help reduce the risk of human error in everything from identifying issues in power lines to predicting equipment failures. As AI adoption grows and the energy sector evolves, these technologies will play a key role in advancing green energy and creating more environmentally friendly power grid systems.
