Transient Thunderstorm Downbursts and Their Effects on Wind Turbines
The International Electrotechnical Commission (IEC) Standard 61400-1 for the design of wind turbines does not explicitly address site-specific conditions associated with anomalous atmospheric events or conditions. Examples of off-standard atmospheric conditions include thunderstorm downbursts, hurricanes, tornadoes, low-level jets, etc. The simulation of thunderstorm downbursts and associated l...
متن کاملDependence of offshore wind turbine fatigue loads on atmospheric stratification
The stratification of the atmospheric boundary layer (ABL) is classified in terms of the M-O length and subsequently used to determine the relationship between ABL stability and the fatigue loads of a wind turbine located inside an offshore wind farm. Recorded equivalent fatigue loads, representing blade-bending and tower bottom bending, are combined with the operational statistics from the ins...
متن کاملAtmospheric stability affects wind turbine power collection
The power generated by a wind turbine largely depends on the wind speed. During time periods with identical hub-height wind speeds but different shapes to the wind profile, a turbine will produce different amounts of power. This variability may be induced by atmospheric stability, which affects profiles of mean wind speed, direction and turbulence across the rotor disk. Our letter examines turb...
متن کاملDamping Wind and Wave Loads on a Floating Wind Turbine
Offshore wind energy capitalizes on the higher and less turbulent wind speeds at sea. To enable deployment of wind turbines in deep-water locations, structures are being explored, where wind turbines are placed on a floating platform. This combined structure presents a new control problem, due to the partly unconstrained movement of the platform and ocean wave excitation. If this additional com...
متن کاملModelling of transient wind turbine loads during pitch motion
In connection with the design of wind turbines and their control algorithms, the transient loads, especially generated by time varying blade loads, are very important. In the Blade Element Momentum method, the most widespread tool in the wind turbine industry, the time constants necessary to describe these problems are not an inherent part of the model. In the present study two different approa...
