So far as electricity production is concerned, hydro-power is the most established and popular renewable resource. As a matter of fact, hydro-turbines have a very quick response for power generation and thus they are capable of handling the load variations. Besides, these can be directly connected to the grid. Among the renewable sources, Micro Hydro Power (MHP) is attractive because of its mature technology, spallation cheap cost, minimum civil work, manageable technology which is robust and reliable that it is applied for controller, generator, and turbine technologies. In this paper, a 60 KW, 132 KV synchronous generator with two controllers are designed and simulated to control the mechanical power input and another controller for controlling the excitation of synchronous generator and synchronous generator output at 13.8 KV is fed to load of 2 KW at 13.8 KV and then this 13.8 KV is stepped down to 400 V to feed the loads of 10 KW and 50 KW. Here 10 KW load is connected through the breaker, to provide load variations and 50 KW load of fixed type. March - May 2017 Copyright © 2017 i-manager publications.
