This paper is concerned with behavior analysis and improvement of wind turbines with Doubly Fed Induction Generator (DFIG) when using a new fractional-order control strategy during wind variations. A doubly fed induction generator, two types of variable frequency power electronic converters and two input wind waveforms are considered. A fractional-order control strategy is proposed for the wind...

In recent years, wind energy has become one of the most important and promising sources of renewable energy. As a result, wind energy demands additional transmission capacity and better means of maintaining system reliability. The evolution of technology related to the wind system industry has led to the development of a generation of variable speed wind turbines that present numerous advantage...

Basically the various challenges of the grid connected DFIG based wind turbine has been highlighted in this review. Nonlinear model of wind turbine with DFIG configuration are explained and a 1.2 MW, 50 Hz, 6 pole DFIG simulated using MATLAB/SIMULINK. Some important control is...

In this Paper Analysis of Calculation Methods to calculate the losses and output power of wind turbine generator systems with using two types first one is Squirrel-Cage Induction Generator and the second is Doubly-fed Induction Generator. By using the existing methods in this paper, we can evaluate the generated output power, total system losses, total energy generated, efficiency and capacity ...

This paper proposes a design of a speed control of three phase induction motor fed from wind turbine using genetic algorithm. The wind turbine acts as a prime-mover for doubly fed induction generator. To make the system stable, proper monitoring is required or sometimes an auxiliary system can also be a good option, which can support the primary system during undesirable conditions. The three p...

The vast majority of wind turbines that are currently being installed use one of the three main types of electromechanical conversion system. The first type is known as the Danish concept. The second type uses a doubly fed induction generator instead of a squirrel cage induction generator. The third type is called the ‘direct-drive wind turbine’ because it does not need a gearbox. In this paper...

The effect of wind generator on sub-synchronous resonance (SSR) is being interested by increasing penetration of wind turbine in power systems,. Purpose of this article is to analyze SSR in a wind farm based on doubly fed induction generator (DFIG) which is connected to compensating series grid. A dynamic model for analysis of induction generator effect and Torsional Interaction (TI) has been u...

This paper presents the study of a variable speed wind energy conversion system based on a Doubly Fed Induction Generator (DFIG) based on a sliding mode control applied to achieve control of active and reactive powers exchanged between the stator of the DFIG and the grid to ensure a Maximum Power Point Tracking (MPPT) of a wind energy conversion system. The proposed control algorithm is applied...
