At present, electrical energy is one of the most useful forms of energy for human beings in the world. Energy in various forms is essential to sustain human life and pursue economic growth. Electrical is to sustain human life and pursue economic growth. Electrical energy can be derived from various sources of energy such as coal, diesel, nuclear, water, steam, wind, solar, heat and so on. The collected data allows for parameter optimization, suitable turbine choice and the design of generator. This paper analysis the turbine selection and generator design of mini-hydropower of Myin War Taung in Hinthada Township Ayerwaddy Division. This is done throughout design and analysis of the electrical generator aspects of the (250 kW) synchronous generator, which was connected to propeller turbine. Modelling and simulation of the system also described by using MATLAB software.
