In this paper, the authors investigated a Direct Drive Permanent Magnet Synchronous Generator Wind Turbine (PMSG-WT). This study deals with control of the PWM back-to-back converter (AC/AC) of the wind turbine, since the average size of WTG installations has increased due to the advent of larger capacity machines, especially variable speed technology, this raise of integration rate of wind ener...

Using the FACTS controllers, such as static synchronous compensator (STATCOM), as it provides continuous reactive power, in the grid including wind turbine (WT) equipped with doubly fed induction generator, for improving voltage profile (under normal circumstances) and providing a transition ability from inductor generator transition state has been proposed. In this paper, in order to contr...

A detailed model of wind power station, including Double Fed Induction Generator, DFIG is presented in this paper. Two control mechanisms are included in the model. The inner control system uses stator flux oriented control for the rotor side converter and grid voltage vector control for the grid side converter. The outer control system is used for wind turbine pitch angle. PSCAD/EMTDC is us...

The aim of this paper is to propose different methods of control for a Doubly-Fed Induction Generator (DFIG) used in wind energy conversion systems. This paper presents a comparative study on the performance of three control methods for DFIG wind turbine. The study focuses on the regulation of the active and reactive power exchanged between the generator and the grid by the generator inverter u...

In the recent years, many wind turbine generation systems (WTGS) have been installed in many countries. However the electric power obtained from wind generators is not constant due to wind speed variations. The generated electric power and the loss in WTGS change corresponding to the wind speed variations, and consequently the efficiency and the capacity factor of the system also change. In thi...

This paper gives an overview of Modeling and simulation of Doubly Fed Induction generator (DFIG) coupled with wind turbine. Latest researches and developments which have been published in imminent journals through rigorous review are overviewed in this paper. Because of the advantages of the DFIG over other generators it is being used for most of the wind applications. Various researches have b...

The increasing penetration of load model in distribution systems may significantly affect voltage stability of the systems, particularly during Low Voltage Ride-Through (LVRT) wind turbine. The main objective of this work is to present the impact of different static and dynamic load models, on the LVRT recovery after disturbances. A component and composite loading structures are considered, com...

This paper presents a terminal voltage control of a wind turbine Self Excited Induction Generator (SEIG). The wind turbine induction generator system is proposed to supply an isolated static load under widely varying conditions. The terminal voltage had been regulated by adapting the value of the excitation capacitance from Static VAR Compensator (SVC) using Artificial Neural Network (ANN) cont...

With the increase of wind turbine dimension and capacity, the wind turbine structures are subjected to prominent loads and fatigue which would reduce the lifetime of wind turbines. Individual pitch control (IPC) is used in this paper to attenuate the blade root bending moment and the tilt and yaw moments and fatigue. The loading transfer from rotational coordinate system to the fixed coordinate...
