Abstract: In recent years, wind power is proved to be the most reliable and developed renewable energy source. The share of wind power with respect to total installed power capacity is increasing worldwide. The evolution of technology related to wind systems leads to the development of a generation of variable speed wind turbines that present many advantages compared to the fixed speed wind turbines. The system studied here is a variable speed wind generation system Doubly Fed Induction Generator (DFIG). The DFIG is one of the popular wind power generator in the wind power industry. The stator of the generator is directly connected to the grid while the rotor is connected through an AC/DC/AC back-to-back PWM converter. In this thesis the steady state performance of DFIG is analyzed. The DFIG is assumed to be connected in power system. The DFIG is modeled as PQ bus for arising the AC system solution. With the help of converged power flow solution, the steady state performance is calculated using Newton Raphson method. Steady state performance of the DFIG is analyzed for its operation at leading power factor, lagging power factor and unity power factor.
