Micro hydro power is considered as one of the lucrative options for electricity generation, it can work both autonomously and in Grid connected mode.Most of the MHP’s are built on obsolete technology due to which only a portion of flow is utilized for power generation. In micro hydro power plant Voltage and frequency of induction generator are not constant due to change in discharge of water.To overcome these issues technology is moving from fixed speed operation (FSO) to variable speed operations (VSO). Doubly Fed Induction Generator (DFIG) is the most suitable option for variable speed operation .In this research paper working and operation of DFIG in MHP system in Grid connected mode is observed which allow to compensate the variations in acceptable proportion while guaranteeing a good quality of electrical outputs.A control algorithm is developed which enable the stator voltage and frequency of DFIG to a constant value in spite of speed variation in driving shaft and load changes. A vector control technique is adopted for the regulation of rotor side converter (RSC) and grid side converter(GSC) to keep the voltages and frequency with in limits and also ensure the reactive power exchange with the grid according to the reference value.Operation of the established model is tested by different operating conditions in Simulink MATLAB.
