The POWERNESTTM system is a wind farm-level control system that integrates various turbine performance optimization function modules. It provides a series of advanced control technologies, including intelligent yaw wind rectification for optimized unit output, environmental perception and adaptation control capabilities, real-time load detection, service life status estimates, and sector management. This system can improve the average annual generation capacity of a wind farm by 2-5%. As of June 2017, this system had been deployed on projects with a total capacity of over 2 million kW and provided an average generation increase in excess of 2%.

EFARM LiDAR Assisted Control Technology

Traditional wind direction and speed measurement instruments are affected by the wake created by blade rotation, which means the measured values and actual values deviate. Our newly-developed front-mounted LiDAR wind measurement technology uses LiDAR units mounted on the turbine to capture the dynamic wind flow in front of the turbine. This information is then input into the turbine's real-time control system for use in advanced control algorithms that optimize the turbine performance, load, and other characteristics. This significantly reduces the unit's load, while improving its generation capacity. This front-mounted LiDAR unit – Efarm – was developed and tested over two years, giving us significant simulation analysis and field testing experience. It allowed us to make a series of important technical breakthroughs in dynamic environmental adaptation, intelligent optimal gain, extreme gust ride-through, and feedforward control. These breakthroughs laid a solid foundation for the decrease of Goldwind turbine loads and promotion of wind zones.
