Wind Energy Conversion System Using Doubly-Fed Induction Generator (DFIG) Technology

In this paper, we explore wind energy conversion systems based on doubly-fed induction generators (DFIG). DFIG technology represents one of the most prevalent wind energy conversion methods, offering significant advantages such as high efficiency and enhanced controllability. The system implementation typically involves rotor-side and grid-side converters controlled through vector control algorithms, enabling independent regulation of active and reactive power. DFIG technology enhances wind power reliability and effectiveness by maintaining consistent output power across varying wind speeds through optimal power tracking algorithms like Maximum Power Point Tracking (MPPT). Modern control techniques including field-oriented control and direct torque control further improve system stability and reliability by providing robust performance under grid disturbances. Looking forward, DFIG technology is expected to maintain its critical role in wind energy conversion, with ongoing developments focusing on advanced fault ride-through capabilities and grid code compliance through sophisticated control system implementations.
