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 کاملCoordinated Control of a DFIG-Based Wind-Power Generation System with SGSC under Distorted Grid Voltage Conditions
Abstract: This paper presents a coordinated control method for a doubly-fed induction generator (DFIG)-based wind-power generation system with a series grid-side converter (SGSC) under distorted grid voltage conditions. The detailed mathematical models of the DFIG system with SGSC are developed in the multiple synchronous rotating reference frames. In order to counteract the adverse effects of ...
متن کاملBehavior 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 کاملImproved control strategies for a DFIG-based wind-power generation system with SGSC under unbalanced and distorted grid voltage conditions ¬リニ
This paper investigates an improved control strategy for a doubly-fed induction generator (DFIG) based wind-power generation system with series grid-side converter (SGSC) under network unbalance and harmonic grid voltage distortion conditions. The integrated mathematical modeling of the DFIG system with SGSC is established by taking both the negative-sequence and harmonic components of the grid...
