Seasonal effects in the long-term correction of short-term wind measurements using reanalysis data [PDF]
Measure–correlate–predict (MCP) approaches are often used to correct wind measurements to the long-term wind conditions on-site. This paper investigates systematic errors in MCP-based long-term corrections which occur if the measurement on-site covers ...

The Power Curve Working Group's assessment of wind turbine power performance prediction methods [PDF]
Wind turbine power production deviates from the reference power curve in real-world atmospheric conditions. Correctly predicting turbine power performance requires models to be validated for a wide range of wind turbines using inflow in different ...

Wear test programs for roller-type pitch bearings of wind turbines [PDF]
Pitch bearings are critical for the safe and efficient operation of wind turbines. They connect the rotor blades to the rotor hub and allow for pitching movements that control loads and rotor speeds.

Wind inflow observation from load harmonics: initial steps towards a field validation [PDF]
A previously published wind sensing method is applied to an experimental dataset obtained from a 3.5 MW turbine. The method is based on a load-wind model that correlates once-per-revolution blade load harmonics to rotor-equivalent shears and wind ...

A vállalati napenergia termelés feltételrendszere = Framework for Corporate Solar Energy Production [PDF]
The production and use of solar energy is increasingly important not only in the private or institution sector, but in the corporate sector as well. However, there are still some elements in the regulatory system that need to be optimized.

Initial results from a field campaign of wake steering applied at a commercial wind farm – Part 1 [PDF]
Wake steering is a form of wind farm control in which turbines use yaw offsets to affect wakes in order to yield an increase in total energy production.

Augmented Kalman filter with a reduced mechanical model to estimate tower loads on a land-based wind turbine: a step towards digital-twin simulations [PDF]
This article presents an application of the Kalman filtering technique to estimate loads on a wind turbine. The approach combines a mechanical model and a set of measurements to estimate signals that are not available in the measurements, such as wind ...
