Performance Study of Grid Connected Doubly Fed Induction Generator Designed for Small Hydropower Plant

The intention of current research exertion is to show the simulation and modeling of the hydro power turbine that is ambitious by the induction generator which is doubly-fed as well as the produced alternating current power prearranged to the grid. Intended for conveyance the alternating current power to the grid, we are applying two PWM voltage source converters which are allied back to back amid the utility grid and rotor terminals with the assist of mutual direct current link. The converter of machine side is used for fitting the excitation. The alternating current power flow in the midst of Alternating Current side and Direct Current bus is proscribed by grid side converter (GSC) as well as it permits the system to be operated in sub-synchronous speed and super- synchronous speed manner of operation. MATLAB/SIMULINK is used for Time domain simulations. The system is stable under different load conditions and that is investigated with the facilitate of model and simulations outcomes. To retain the system stability at whatever time the alternating current power stipulate is abruptly increasing in the utility grid side, induction generator which is doubly-fed (DFIG) system and Proportional integral (PI) controller is used.
