Behavior of DFIG Wind Turbine during Unbalanced Grid Voltage
The use of doubly fed induction generators (DFIGs) in wind turbines has become quite common for the last few years. These machines provide variable speed and are driven with a power converter which is sized for a small percentage of the turbine-rated power. This paper presents a detailed model of an induction generator coupled to wind turbine system. Modeling and simulation of the induction mac...
متن کاملDirect Power Control of a Dfig-based Wind Turbine under Unbalanced Grid Voltage without Rotor Position Sensor
In this paper, the behavior of a doubly fed induction generator (DFIG) is proposed under an unbalanced grid voltage and without using a rotor position sensor. There are two main methods that have been used for the detection of rotor position: use of a shaft sensor and use of a sensorless algorithm. In this paper the shaft sensor is eliminated and a position sensorless algorithm is used for esti...
متن کاملA Novel Control Scheme for DFIG-based Wind Energy Systems under Unbalanced Grid Conditions
This paper presents an analysis and a novel control scheme for a doubly-fed induction generator (DFIG) based wind energy generation under unbalanced grid conditions. The control objectives are: (i) to limit the rotor currents, (ii) to suppress ripples in the torque and (iii) to suppress the dc-link voltage fluctuation through converter controls. Negative sequence compensation techniques by one ...
متن کاملAn Improved Control Method for a DFIG in a Wind Turbine under an Unbalanced Grid Voltage Condition
This paper presents a control method, which reduces the pulsating torque and DC voltage problems of a doubly fed induction generator (DFIG)-based wind turbine system. To reduce the torque and power ripple, a current control scheme consisting of a proportional integral (PI) controller is presented in a positive synchronously rotating reference frame, which is capable of providing precise current...
متن کاملLow 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...
