1 Hydropower -Fundamentals -Water Turbines

2 Fundamentals of Hydropower a. Type of Hydrosystem Low head (run of the river only) Medium head (stored only) High head (run of the river or stored)

3 Fundamentals of Hydropower a. Type of Hydrosystem Large scaleSmall scale (<1MW) Cheaper per kW Quick import – delivered on a turnkey basis Little (or no) dependence on overseas technologies Capacity building –Can use local labour/materials Can serve urban demandClose to (rural) users Fisheries/leisureMostly “run of river” so no reservoir problems

4 Fundamentals of Hydropower b. Parts of Hydrosystem: Ideals 1 1 1 1 2 2 3 3 4 4 5 5 Letaknya harus dekat dengan pemukiman untuk mereduksi biaya transmisi dan juga mudah diakses (e.g maintanace) Harus dapat mengatasi flow yang sangat besar yang diperlukan oleh turbin Panjangnya diusahakan sependek mungkin??
