Stator field control of DFIG for wind energy systems

Abstract

The growing demand for electric power around the world has led to an increased consumption of fossil fuels (oil, coal and gas). The impact these energies on the environment has led modern societies to seek sustainable alternatives to meet industrial and industrial needs and requirements ever-increasing daily life. This approach has led to the implementation of renewable energy sources.More and more countries are being made aware of the essential nature of the advance of renewable energy in the fight against climate change and of increasing access to energy for the benefit of populations still deprived of any modern energy service.Wind energy is one of the forms of renewable energy; it takes its name from Eole, the name given to the god of the wind in ancient Greece. It is an energy that is directly drawn from the wind using a wind turbine device. The development and exploitation of wind energy has increased in recent years, especially in countries.Wind energy is now attracting the interest of several research teams. These systems that produce electrical energy from the wind can be a technological and economic alternative to the various sources of harmful energy exhausting at the same time.The purpose of this work, we will study the direct vector control of the DFIG based on the orientation of the stator flux, used to make it work as a generator. The latter highlights the relationships between stator and rotor magnitudes. These relationships will make it possible to act on the rotor signals in order to control the exchange of active and reactive power between the stator of the machine and the network. We will simulate the whole overall system using MATLAB software
