In the evolving field of wind energy, optimizing wind parks effectively is crucial for improving performance and ensuring reliable operations. Traditionally, physics-based models have guided these efforts. However, at Turbit, we have opted for a data-driven approach by employing neural networks and artificial intelligence (AI). This article explores why neural networks are becoming the preferred method for optimizing wind parks and how they compare to traditional physics-based models.
Comparing Physics-Based Models with Neural Networks
Physics-based models have been essential in wind park optimization, relying on fundamental physical principles and equations to simulate turbine behavior. These models take into account variables such as wind speed, turbine blade angles, and atmospheric conditions to predict energy output and identify inefficiencies.
Despite their foundational role, physics-based models have limitations:
Complexity and Assumptions: These models may struggle to capture the full complexity of real-world conditions and rely on static assumptions that may not reflect dynamic changes accurately.
Adaptability Issues: Adjusting physics-based models to new data or evolving conditions can be time-consuming, requiring significant recalibration.
Neural networks, a key component of AI models, offer several advantages:
Advanced Pattern Recognition: Neural networks excel at identifying complex patterns within large datasets, providing insights that traditional models may miss.
Dynamic Learning: These networks continuously learn from new data, adapting in real-time to changes in wind conditions, turbine performance, and other variables.
Enhanced Predictive Accuracy: Neural networks leverage vast amounts of data to make highly accurate predictions and detect subtle anomalies that may not be visible through traditional methods.
Why We Choose AI Models: A Data-Driven Approach
At Turbit, we have opted for a data-driven approach by leveraging neural networks, aligning with our commitment to innovation and efficiency. Here’s why:
Scalability: Neural networks handle large volumes of data efficiently, making them well-suited for monitoring and optimizing numerous turbines across extensive wind parks.
Preventing Downtime: Real-time data analysis helps us predict and address potential issues before they lead to significant downtimes, maintaining operational efficiency.
Mitigating Risk: Advanced predictive capabilities allow us to identify risks early, enabling timely corrective actions and reducing the likelihood of costly disruptions.
Time Savings in Operations and Asset Management: Neural networks streamline data processing, enhancing the efficiency of operations and asset management, and reducing time spent on manual analysis.
Independence from Specific Sensors: AI models can create effective monitoring systems regardless of the data quality or presence of specific sensors, addressing a major challenge in data science.
Innovation Speed: We can develop new monitoring systems for various sensors within a week, without needing to understand the underlying physics of the components, allowing rapid adaptation and deployment.
Customized Models: Neural networks enable us to train individual models tailored to each turbine and its components, benefiting from transfer learning and extensive data to improve accuracy, particularly in predicting failure modes.
Our Neural Network Ecosystem: A Closer Look
Currently, Turbit monitors approximately 2,500 turbines, with over 12,000 neural networks in production. Each turbine can have up to six neural networks, focusing on various performance and condition aspects. Here are examples of the data we analyze:
Temperature Data: Monitoring temperatures of critical components such as gearboxes, generators, and power converters to ensure they operate within optimal ranges.
Power Data: Tracking power output to identify inefficiencies and optimize energy production.
Oil Data: Assessing lubricant conditions to predict maintenance needs and prevent potential component failures.
Generator Bearings: Monitoring the condition of generator bearings to ensure smooth operation.
Main Bearing: Tracking the health of the main bearing for early detection of wear and tear.
Pitch Behavior: Analyzing pitch behavior to optimize turbine performance and efficiency.
Each turbine’s unique characteristics are taken into account, ensuring precise and effective monitoring.
