    wind farm interconnection study

    Thanks all for your answers .They help. The turbines are being modelled as doubly fed type 3 induction machines where aspen requires to keep sub transient ,positive ,and negative sequence impedances equal to the sub transient reactance with some very high zero sequence reactance.If I have to a...
