This project builds a model-agnostic LLM pipeline aimed at solving the challenge of analyzing unstructured maintenance logs in wind power operation and maintenance. By automatically standardizing, classifying, and extracting reliability intelligence from maintenance work orders, it provides data-driven intelligent operation and maintenance solutions for the renewable energy industry. The core innovation lies in combining the natural language understanding capabilities of large language models with industrial operation and maintenance scenarios, supporting flexible selection of different LLMs (such as OpenAI GPT, Anthropic Claude, open-source Llama, etc.) to balance data privacy and model capabilities.

Wind energy is one of the fastest-growing renewable energy sources globally, and operation and maintenance efficiency directly affects power generation costs and equipment lifespan. Maintenance records of modern wind farms are mostly unstructured text (such as technician notes, fault descriptions). Traditional manual analysis is time-consuming and labor-intensive, making it difficult to extract key reliability intelligence like fault patterns and component failure rules from massive data, which has become a bottleneck for operation and maintenance efficiency.

The core of the project is to build a robust model-agnostic LLM pipeline that achieves three main functions:

1. Automatic Standardization: Unify fault records with different expressions (e.g., "gearbox oil leakage" and "transmission oil seepage") through LLM semantic understanding;
2. Intelligent Classification: Multi-dimensional classification (fault type, component location, severity level, maintenance type);
3. Reliability Intelligence Extraction: Extract deep information such as fault patterns, root cause clues, maintenance measures, and time rules.

The pipeline supports multiple LLMs, and users can flexibly choose based on cost, performance, or privacy requirements.

Key technical implementation points:

• Prompt Engineering + Few-Shot Learning: Guide LLMs to understand wind power professional terms and context through carefully designed prompts and typical examples;
• Structured Output and Validation: Constrain the model to output JSON format, perform post-processing to verify completeness, and mark low-confidence results for manual review;
• Batch Processing and Scalability: Support asynchronous processing, rate control, and error retries for large-scale historical records to adapt to different LLM API limits.

Application scenarios and value:

• Predictive Maintenance: Identify equipment health trends and prevent faults in advance;
• Spare Parts Inventory Optimization: Optimize inventory strategies based on fault data to reduce costs;
• Supplier Quality Evaluation: Track component failure rates to support procurement decisions;
• Knowledge Transfer: Structured historical cases help train new engineers.

Technical challenges and solutions:

• Domain Term Understanding: Add glossaries and domain examples to prompts, and perform lightweight domain adaptation if necessary;
• Data Privacy Compliance: Deploy open-source models locally or perform data desensitization to ensure sensitive information security;
• Cost Control: Incrementally process new records, cache results, and select cost-effective models to reduce API call costs.

This project demonstrates the great potential of LLMs in the industrial operation and maintenance field. The model-agnostic design makes it versatile and expandable to other industrial scenarios such as equipment manual parsing and fault report analysis. With the growth of global wind power installed capacity, such intelligent tools will become key support for the industry's digital transformation, providing reference cases for AI applications in industry.
