In this report, work done to develop generator model using MATLAB (Matrix laboratory) environment is explained. The main aim of the project was to develop an excellent Doubly fed induction generator model. The model can be used to understand, simulate and analyze transients load. The simulation of the model under different grid condition and articulation of the resonant excitation would be possible. This report also contains the technology of generator systems in wind energy conversion systems which are already in use and some of the new concepts and their technical features. The new generator technologies could generate invariable wind power and does not depends on the changes happen in the velocity of the wind. It has huge application across the globe and especially at the remote areas of the world.

In recent years, renewable energy has become one of the most important and promising sources of energy generation, which demands additional transmission capacity and better means of maintaining system reliability. The evolution of technology related to wind systems industry leaded to the development of a generation of variable speed wind turbines that present many advantages compared to the fixed speed wind turbines. These wind energy conversion systems are connected to the grid through Voltage Source Converters (VSC) to make variable speed operation possible. The studied system here is a variable speed wind generation system based on Doubly Fed Induction Generator (DFIG). The rotor side converter (RSC) usually provides active and reactive power control of the machine while the grid-side converter (GSC) keeps the voltage of the DC-link constant. The additional freedom of reactive power generation by the GSC is usually not used due to the fact that it is more preferable to do so usin...

Design and Modelling of Induction GeneratorWind power Systems by usingMATLAB/S IMULINK2014 •
This paper describes the performance comparison of a wind power systems based on three different induction generators. The three induction machines studied for the comparison are the squirrel-cage induction generator (SCIG), the doubly fed induction generator (DFIG) and using a doubly fed induction generator in single-sided grid connection. The performances are compared between the SCIG, DFIG and DFIG in single-sided grid connection systems. The SEF-DFIG stator of the machine is connected with a direct power grid, and the rotor is controlled by an inverter without any external power source. In this paper, for applying the proposed scheme to the wind turbine, the design and modelling of the induction generators simulated in MATLAB/SIMULINK environment

Modelling and control of wind turbine doubly fed induction generator with MATLAB Simulink2017 •
This paper describes the modelling and control system of a wind turbine, using a doubly fed induction generator. This configuration makes the wind turbine suitable for variable speed wind energy application. The power captured by the wind turbine is converted into electrical power by the induction generator, and it is transmitted to the grid by the stator and the rotor windings. The control system generates voltage command signals for rotor converter and grid converter, respectively, in order to control the power of the wind turbine. Reactive power exchanged with the network through the converters is set to 0 VAr. The control strategy has been developed using MATLAB/Simulink. The simulation results are presented and discussed in the conclusions.

This work is based on the dynamics of wind energy generation considering the wind speed and the control of the rotor speed using vector control of the converters. The converters are both connected to the rotor side and grid side of the doubly fed induction generator (DFIG), pulse width modulated (PWM) generators powering the switches are controlled using various vector transformation and proportional integral (PI) control of the direct and quadrature current and the speed of the rotor. It is found that at an average wind speed of about 8.5 m/s a considerable voltage and current characteristic is evolved whereas at wind speed of about 2 m/s, the amount of voltage generated is seen not to compare favorably to the former. The modelling and simulation of this work was done using MATLAB and Simulink software.

Operation and Analysis of Doubly-Fed Induction Generator Based Wind Turbine Model under Normal and Transient Conditions2020 •
Renewable energy resources are the major sources of energy for human being and current industrial applications. Exhausting resources such as petroleum, gas, coal and other non-renewable energy resources are depleting day by day and causing global warming. Due to this reason national and international trend of generating energy is moving to the renewable and clean energy resources. Energy from the wind is one of the prominent sources of production of electricity. Wind turbines are employed for electrical energy generation. Many types of AC generators have been employed for converting the rotational energy in form of mechanical energy from wind turbine into electricity. Doubly-fed induction generator is the prominent and escalating kind of generator employed in wind energy conversion system. Energy from the wind might be varied randomly therefore system reliability and stability is needed. The major purpose of this research work is to implement the grid connected wind turbine model and investigate the voltage and current profiles of system at normal condition and transient fault condition.
