Wind farm operations are becoming increasingly sophisticated and data-driven. By precisely controlling every aspect of wind farm operations—including operation, maintenance, and management—companies can achieve optimal resource allocation and maximize operational efficiency. Compared to traditional, extensive operating approaches, refined operations can increase wind farm power generation by 5% to 10% and reduce operation and maintenance costs by 15% to 20%, significantly enhancing the profitability of wind farms.
Optimizing operating parameters is a crucial component of refined operations. By analyzing historical wind speed data and unit operation data, wind farms can set personalized operating parameters for each turbine. When wind speeds are low, the turbine’s cut-in wind speed threshold is appropriately lowered to enhance its ability to capture wind energy. When wind speeds are high, the pitch angle control strategy is optimized to ensure stable turbine operation while maximizing power generation. At a wind farm in northwest China, parameter optimization has increased the annual power output of a single turbine by approximately 30,000 kilowatt-hours, resulting in an overall annual increase in power generation for the entire farm exceeding 1 million kilowatt-hours.

Fine-grained operations and maintenance management has significantly boosted O&M efficiency. The wind farm has established a predictive maintenance system based on equipment condition, which uses real-time monitoring of equipment operating data to identify potential faults in advance and schedule maintenance activities accordingly. At the same time, inspection routes and inspection cycles have been optimized, and technologies such as drone inspections and remote monitoring have been adopted to reduce unnecessary inspections. At a wind farm in North China, fine-grained O&M has reduced the number of inspection personnel by 30%, while the timely repair rate for equipment failures has increased to 98%.

Fine-grained cost control has effectively reduced operational expenses. By establishing a comprehensive cost accounting system, the wind farm achieves precise control over various costs, including operation and maintenance materials, labor, and energy consumption. In terms of spare parts procurement, the farm has lowered procurement costs through centralized purchasing and long-term partnerships. Regarding energy consumption management, it has optimized the operating strategies for auxiliary equipment at the wind farm, thereby reducing the on-site power consumption rate. Thanks to this refined cost control approach, one wind farm has reduced its annual operation and maintenance costs by 2 million yuan, and its on-site power consumption rate has dropped from 5% to 3.5%.

Refined personnel management has enhanced the team’s combat effectiveness. The wind farm has established a comprehensive performance evaluation system that links indicators such as power generation, equipment failure rates, and cost control to employees’ salaries, thereby boosting employee motivation. At the same time, the company has strengthened staff skills training to cultivate versatile talents who are “specialized in one area yet capable of performing multiple tasks.” At a wind farm in South China, refined personnel management has increased employee work efficiency by 40%, significantly enhanced the team’s innovation capabilities, and led to the submission of 12 operational optimization proposals within just one year, generating substantial economic benefits.
