Mostly the small hydro power plants built on a run of river, they are without any water storage capability. When enough water is available in the river then the power can be generated. In this research paper I discussed the maximum power extracted through run off river plant using doubly fed induction generator. Now a day for variable speed turbines doubly fed induction generator is the most suitable machine to extract electrical power from the energy source. In this research paper I proposed a study of variable speed turbine on a run off river plant using doubly fed induction generator. Usually electrical power is extracted from variable speed small hydro turbine through synchronous or induction generator but in both cases voltage magnitude and frequency change with changing of discharge. In proposed research paper I stabilize frequency and magnitude of voltage by doubly fed induction generator. The entire model has been verified by simulation using MATLAB/simulation environment under the various situation, such as discharge values and different reference reactive power on rotor side converter and also on different reference reactive power on grid side converter. From the simulation results and investigation we can say that p doubly fed induction generator model can extract maximum power from run off river without affecting the voltage magnitude and frequency and reactive power control between grid and DFIG.
