The power extracted from the water i-e hydropower is one of the clean and economical source for the generation of power. The flow of water does not remain constant throughout the year so we have to build large storage tanks i-e dams to store water for power generation. But building these large dams have limited this source of energy. Consequently, the trend is going to change by building small hydropower plants. There is no availability of storage of water for producing power then mostly small hydro power plants are built there which are also called as run off river plants. The flow of water vary throughout the year resulting in inconsistent generation of power.so there is a need of variable speed operation that can operate at different operating point to achieve maximum efficiency. So for varying speed operation the one of the famous operating system that is doubly fed induction generator can be used to achieve desired results. In this work the DFIG in a MHPP’s is studied, there steady state and dynamic models are discussed. The 3 phase voltages and currents are transformed into 2 phase for ease in calculation by using Clark and park transformation. Then doubly fed induction generator has to operate at the required references which are reactive power, active power and also for speed. And eventually the model of vector control of doubly fed induction generator is achieved. The main objective of developing the model of doubly fed induction generator is to manage the two powers (i-e reactive and active power). The whole simulation should be carried out in MATLAB/Simulink. In this model of doubly fed induction generator we are using two different type of controllers, i-e Proportional integral and Proportional Integral Derivative controllers, to check the efficiency of the model. The results which are then obtained such as the torque, speed, rotor current, voltages on the rotor side as well as Bus voltage, reactive power on the grid side obtained from the two controllers are then compared with each other to see that which controller is giving good efficiency. Therefore, in this research, a predictive controller is proposed to manage the powers i-e active and reactive, of a hydropower plant using doubly fed induction generator.
