As of December 15, PetroChina's first large-scale green power export project—the Angge Wind Power Project in Jilin Oilfield, also the largest single wind power project in Jilin Province—has cumulatively generated over 1.1 billion kWh of electricity since its operation began. This output is equivalent to saving approximately 335,000 tons of standard coal and reducing carbon dioxide emissions by about 914,000 tons.
Located in Qianguo County, Songyuan City, Jilin Province, the Angge Wind Power Project is equipped with 88 wind turbines, each with a capacity of 6.25 MW, totaling an installed capacity of 550 MW. Since its completion and commissioning, Jilin Oilfield has continuously enhanced operational efficiency by implementing a refined management system that integrates "defect management" and "economic operation" in a dual closed-loop framework, maintaining high equipment availability rates.
To improve wind farm management effectiveness, Jilin Oilfield has established a rapid response and defect control mechanism. This includes creating a comprehensive equipment checklist, defining inspection frequency, routes, and standards, and dynamically updating digital defect logs to ensure safe and controllable operational conditions.
For economic operation, the company employs data-driven decision-making by consolidating multi-dimensional data from SCADA systems and power curves. Comparative analyses—year-on-year, quarter-on-quarter, and cross-sectional—are conducted to quickly identify underperforming turbines. For "suboptimal" units, a tailored "one-turbine-one-strategy" approach is applied for precise maintenance and optimization. Continuous monitoring of turbine performance has led to overall efficiency improvements across the entire facility.
