system is a wind farm-level control system that integrates various turbine performance optimization function modules.
World's first laser-aided turbine control
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. Goldwind’s 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, EFarm, 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 was developed and tested over two years, yielding significant simulation analysis and field-testing experience. As a result, Goldwind has made important technical breakthroughs in dynamic environmental adaptation, intelligent optimal gain, extreme gust ride-through, and feedforward control.
Goldwind has received the world’s first component certification from DNV GL for a Lidar-aided control system, a technology that will revolutionize wind turbine power production by reducing loads on blades by as much as 20% during operation.
