Study on Different Fault Detection Techniques and Control Strategies in DFIG

Doubly Fed Induction Generator (DFIG), is a type of electrical generator which is mostly and popularly utilized with wind turbines for wind Energy Conversion System. It is a versatile technology that may be used in various sectors and may play a State of Art Technological Revolutionary role for Renewable Power Generation. DFIG is a State of Art Technology for power generation through wind due to its variable speed capabilities, Optimum efficiency, and cost-effectiveness. Its ability to operate at partial load and yield reactive power to the grid, makes it an ideal choice for wind Energy Conversion System. These factors motivate the author to go in deep with DFIG. This paper provides the working mechanism of DFIG with benefits and Limitations. While DFIG has many advantages in wind power generation, but there are also some limitations to this technology. DFIG, can experience various types of faults that can affect its operation and performance. To control these faults different control strategies or systems has to be applied in it. In this paper, Author tries to covers these types of faults and control strategies, applied to control these faults.
