Unit's characteristic is the stator direct incorporation, and through the excitation frequency changer control rotor current frequency, the phase and the peak-to-peak value comes the indirect control stator side the output.This kind of structure cannot separate between DFIG and the electrical networ

Units feature is direct grid-connected stator and rotor excitation inverter current's frequency, phase and amplitude to indirectly regulate the stator output power. This structure cannot be separated DFIG and the links between the network and cause the unit to the power grid and is particularly sens
