Active Power Control in Doubly Fed Induction Generator by Using PID Control Technique

This paper deals with control strategy of active power of Doubly Fed Induction Generator (DFIG) by using PID controller. The active power control of wind farms becomes major concern of stability and security of entire power system. Control over active power according to dispatch command means the wind farm should behave in some way more similar to the conventional power plants. Doubly Fed Induction Generators (DFIG) are generally used in power plants due to capability of decoupled active and reactive power control. This paper describes design and simulation of DFIG using back to back voltage source PWM converter, converter switches gets signal by PID controller attach to output of comparator circuit & rotor circuit using MATLAB Simulink environment. Vector control scheme for supply side PWM converter results in active and reactive power control
