May require controller upgrade to VMP Global. ***High Wind Operation is a standard feature on the turbine • The HWO control feature gradually reduces energy production by following a de-rating profile, thereby enabling extended wind turbine operation beyond standard cut-out wind speeds. Additional energy production When the wind speed exceeds the standard cut-out point of a wind turbine, Vestas’ HWO enables the turbine to keep producing electricity. This continued energy production beyond the standard cut-out wind speed can improve annual energy production by up to 0.8 percent*. Improved reliability The Vestas HWO control feature results in fewer hysteresis-related stop-and-start operations due to the cycle moving to higher wind speeds with fewer expected operating hours. As a result, the frequency of associated hysteresis loops are reduced, which can increase the number of production hours as well as limit the strain on wind turbine components. For more information Vestas HWO provides extended wind turbine operation for improved output stability, energy production and reliability.
