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 کاملSliding-Mode-based Improved Direct Active and Reactive Power Control of Doubly Fed Induction Generator under Unbalanced Grid Voltage Condition
This paper proposes an improved direct active and reactive power control (DPC) strategy for a grid-connected doubly fed induction generator (DFIG) based wind-turbine system under unbalanced grid voltage condition. The method produces required rotor voltage references based on the sliding mode control (SMC) approach in stationary reference frame, without the requirement of synchronous coordinate...

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 کاملIntegral Plus Resonant Sliding Mode Direct Power Control for VSC-HVDC Systems under Unbalanced Grid Voltage Conditions
An integral plus resonant sliding mode direct power control (IRSMC DPC) strategy for voltage source converter high voltage direct current (VSC-HVDC) systems under unbalanced grid voltage conditions is proposed in this paper. Through detailed instantaneous power flow analysis, a generalized power compensation method, by which the ratio between the amplitude of active and reactive power ripples c...
