High Wind Ride Through Providing more predictable power output The Siemens High Wind Ride Through application allows a wind turbine to operate at some storm-level wind speeds and is a breakthrough in stabilizing energy output. High Wind Ride Through is an intelligent solution for both onshore and offshore wind turbines that enables more stable energy production. When the wind speed is higher than 25 meters per second, wind turbines typically shut down in order to avoid overload due to extreme loads. Equipped with High Wind Ride Through, the wind turbine will gradually reduce power output instead of shutting down completely. This results in a more stable power output at high wind speeds. As a result, the operating range of the wind turbine at high wind speeds is extended, while remaining loadneutral. This is achieved by intelligently pitching the blades out of the wind as soon as the rated power output is reached and by limiting rotational speed in proportion to the increase in wind speed and turbulence intensity. The gradual derating eliminates abrupt cutouts, which significantly improves grid stability. This is an advantage, especially for larger wind farms where commitment to a certain level of energy production is often required. Answers for energy.

Minimizing the occurrence of hysteresis loops can increase the wind turbine's production time. Key benefits of High Wind...
