Sentence examples for frequency of the wind from inspiring English sources

The decrease of free aperture separation reduces the enclosure flow rate whilst the frequency of the wind flow almost maintains at a constant value.

In this study, the frequency of the wind farm is used as the frequency regulation target, and fref (1,2) = 50 ± x Hz is selected as the frequency regulation dead band.

In this framework, the fixed base natural frequency of the wind turbine is first calculated and is then multiplied by two non-dimensional factors to account for the foundation flexibility (i.e. the effect of soil structure interaction).

In this paper, an internal model control (IMC) method with an adaptive algorithm is implemented to first identify the vibration frequency of the wind turbine tower and then to cancel the vibration signal.

According to this study, our GIS methodology is based on 500 meter and 1000 meters buffers, the frequency of the wind direction (data from Meteo France®), the presence of topographic barriers (BD Alti, IGN), vegetative barriers (BD Topo®, aerial photography and/or remote sensing), and structural barriers (BD Topo®, aerial photography and/or remote sensing).

Based on the measurement of voltage and frequency of the wind-turbine generator and the grid side, a control decision is taken to connect the system to the grid.

Thus, the tower foundation system could potentially become near-resonant with the operational frequencies of the wind turbine.

Those fluctuations are due to successive lock-ins of the wind speed dependent shear layer instability of the jet, with acoustic resonant frequencies of the wind tunnel.

Icing frequencies of the wind sensors at the stations were detected based on measured temperature, relative humidity and the standard deviation of the lateral movement of the wind sensor.

The wind turbine mechanical resonance frequencies may be within the typical range for power system oscillations, which may limit the frequency range; then an active power modulation controller should be used to avoid exciting oscillations at mechanical resonance frequencies of the wind turbine.

When the SoC of the battery reaches the value of 100%% and frequency is set to 51 Hz, at t = 1.5 s, the over/under frequency relay of the wind generators (R14) is activated and disconnects them from the microgrid, resulting in a new power balance.
