Power and Current Limiting Control of Wind Turbines Based on PMSG Under Unbalanced Grid Voltage

Also Available Domains Power Quality

Project Code :TEPGPS435


: The main objective of this project is to limit the current, power and enhance the operation of wind power system during unbalanced grid voltage conditions.


This paper proposes a simple current limiting control scheme without auxiliary equipment, which based on the detailed analysis of the excessive peak current. In this scheme, the Machine Side Converter (MSC) controller adjusts the electromagnetic power according to the power transmitted to the grid by the Grid Side Converter (GSC). Meanwhile, it converts the unbalanced power on the dc-link into the rotor kinetic energy, avoiding the dc-link overvoltage. 

The GSC controller can not only ensure that the three-phase inverter currents are in the maximum safe range that the converters can bear, but also provide reactive power support for the grid. Furthermore, the fluctuations on dc bus voltage and output power can be eliminated effectively by using the GSC controller. 

The feasibility of the proposed scheme and the superiority over the traditional control schemes have been verified by simulations under different types of unbalanced voltage.

Keywords: Unbalanced grid voltage, peak current, current limiting control, rotor kinetic energy,

reactive power support.
