Wind Turbine Tower Resonance
Wind turbine towers are large structures designed to withstand the unique loading conditions imposed on them by the turbine’s nacelle and dynamic forces from the rotating blades. Observations and noise measurements of a particular wind turbine showed high noise levels at approximately 48 Hz, which could not be explained from the usual known potential noise sources. Correlated far field noise me...
متن کاملEffect of Tower Shadow and Wind Shear in a Wind Farm on AC Tie-Line Power Oscillations of Interconnected Power Systems
This paper describes a frequency domain approach for evaluating the impact of tower shadow and wind shear effects (TSWS) on tie-line power oscillations. A simplified frequency domain model of an interconnected power system with a wind farm is developed. The transfer function, which relates the tie-line power variation to the mechanical power variation of a wind turbine, and the expression of th...
متن کاملAnalysis of Tower Shadow Effects on Battery Lifetime in Standalone Hybrid Wind- Diesel-Battery Systems
In a standalone hybrid wind-diesel-battery system, the battery lifetime is often optimistically overpredicted by hybrid system designers and battery manufacturers. As a result, battery replacement takes place more often than required. One of the reasons is due to the underestimation of battery wear from the short charge-discharge cycles, otherwise known as microcycles. A microcycle takes place ...

متن کاملInvestigation of Vertical Wind Shear Characteristics Using 50m Meteorological Tower Data
Wind measurement is important for estimating wind energy potential, but it is relatively cost-intensive and often conducted at a narrow height from the ground level. The typical range of most turbine hub heights is from 30-50 m or even higher. Extrapolation on wind data thus becomes necessary to estimate the wind speed at different heights. Doing so requires the essential understanding of wind ...
