The Research of Reactive Power Output of Doubly-Fed Induction Generator when Large-Scale Wind Power Integration

Abstract:

The technology of large-scale wind power connected to grid is a key technology in the application of wind power. However, the large-scale wind power will cause the negative effect on the voltage of grid. So, the regulation of reactive power is necessary, which can stabilize the voltage level of the grid. The doubly-fed induction generators (DFIG) themselves own the ability of providing reactive power. Considering the reactive power demand when the power grid is operating, and then rationally allocating static and dynamic reactive power compensation equipment, the operational efficiency can be improved. The particle analyzes the reactive power limit of DFIG, considering the limit of stator and rotor. In this way, the reactive power compensation capacity of DFIG is used first, the use of reactive power compensation equipments are greatly reduced, so the economy of the wind farm is obviously improved.
