A mountain with wind turbines

How do mountain waves affect wind turbines?

Called mountain waves, these oscillations can have big impacts on power generated by wind turbines, because they also cause oscillations in wind speed at the height of wind turbines.

Does a wind farm affect environmental characteristics in a mountain region?

In the present study, we reported an absence of impact of the turbine as assessed by plant ecological indicators, suggesting that the wind farm did not significantly alter the environmental characteristics in the studied mountain region.

Why are mountain wind farms more complex than flat wind farms?

In the mountain wind farms in southern China, the wind resource conditions are more complex than in flat wind farms as a result of the complex terrain. WT failures caused by frequent starting of the yaw system are common, resulting in significantly reduced economic benefits over the WT life cycle.

What is a giant wind turbine?

Today, giant wind turbines are multimegawatt generators with rotor diameters of more than 100 m. As a result, for wind-turbine installations, it is critical to locate places with high wind speeds, as this produces a larger electrical energy production .

What is a mountain wave in a simulated wind field?

Mountain waves can be seen in the simulated horizontal wind field at 100 m a.g.l. (Fig. 4a) as relatively thin and similarly spaced oscillating strips of high and low wind speeds oriented approximately perpendicular to the wind direction.

Do mountain waves affect wind farm power output and nacelle wind speed?

When analyzing wind farm power output and nacelle wind speeds, we found that even small oscillations in wind speed caused by mountain waves can induce oscillations between full-rated power of a wind farm and half of the power output, depending on the position of the mountain wave's crests and troughs.
