Low Voltage Ride Through Enhancement Based on Improved Direct Power Control of DFIG under Unbalanced and Harmonically Distorted Grid Voltage
In the conventional structure of the wind turbines along with the doubly-fed induction generator (DFIG), the stator is directly connected to the power grid. Therefore, voltage changes in the grid result in severe transient conditions in the stator and rotor. In cases where the changes are severe, the generator will be disconnected from the grid and consequently the grid stability will be attenu...
متن کاملLow voltage ride-through capability improvement of DFIG-based wind turbines under unbalanced voltage dips
This paper proposes a competent and effective scheme to enhance the ride-through capability of DFIGbased wind turbines under unbalanced voltage dip conditions. The proposed method is realized through joint use of the rotor-side converter control and a three-phase stator damping resistor (SDR) placed in series with the stator windings. By means of an asymmetrical SDR idea, during the unbalanced ...
متن کاملImproved Control Strategy for Low Voltage Ride Through Capability of DFIG with Grid Code Requirements
This paper deals with a protection and control strategy to enhance the low voltage ride through capability of a wind turbine driven doubly fed induction generator (DFIG). As the wind power penetration continues to increase, wind turbines are required to provide Low Voltage Ride-Through (LVRT) capability. Crowbars are commonly used to protect the power converters during voltage dips and their ma...
متن کاملLow Voltage Ride through Capability Improvement of Dfig Based Wind Turbine Using Statcom
This paper studies a control strategy to improve low voltage ride through (LVRT) capability of doubly fed induction generator (DFIG)-based wind turbine (WT). This solution is based on the DFIG with Crowbar circuit control and the installation of STATCOM which is connected at the point of common coupling (PCC). The simulation model of WTs with STATCOM is built using the environment MATLAB/Simuli...
متن کاملDecoupled Feed Forward Voltage Oriented Controller for DFIG under Balanced and Unbalanced Fault Conditions
As Wind Power Penetration increases continuously in total Power Generation, the wind turbines are necessary to stay connected to grid even under grid disturbances. An enhanced control strategy for DFIG is proposed in the present paper to meet the latest grid codes set by grid operators. The Decoupled Current Controller implemented in Grid Voltage oriented reference frame is applied to Grid Side...
