This model is a partial class extended by three-phase unbalanced wind turbine power sources.
The model has boolean parameters plugPhase1,
plugPhase2, and plugPhase3 that can be
used to connect the wind turbines in an unbalanced
configuration.
The model has an array scaleFraction[3] that is
used to determine how to partition the power of the wind turbines
on the three-phase. By default it is assumed a uniform partition
scaleFraction[3] = {1/3, 1/3, 1/3}.
