WindTurbineCluster.mean_hub_height()[source]¶

Calculates the mean hub height of the wind turbine cluster.

The mean hub height of a wind turbine cluster is necessary for power output calculations with an aggregated wind turbine cluster power curve. Hub heights of wind farms with higher nominal power weigh more than others. After the calculations the mean hub height is assigned to the attribute hub_height.

Returns:: self
Return type:: WindTurbineCluster

Notes

The following equation is used [1]:

$h_{WTC}=e^{\sum\limits_{k}{ln(h_{WF,k})} \frac{P_{N,k}}{\sum\limits_{k}{P_{N,k}}}}$

with:: $h_{WTC}$ : mean hub height of wind turbine cluster, $h_{WF,k}$ : hub height of the k-th wind farm of the cluster, $P_{N,k}$ : installed power of the k-th wind farm
