Hydro power energy generation of run-off river type by using plural flow duration curve

Abstract

This research intends to present a new method about the discharge modeling for mini-hydro power so it can be obtained the maximum energy. The methodology consists of modelling by the plural Flow Duration Curve (FDC). By using this method, it is hoped that the hidden discharge potency on a river can be appear and optimally used. The detail methodology is as follow: to analyze the available dependable discharge in the Konang watershed, to know the condition of Konang watershed based on the ratio pf Qmax/Qmin, to determine the suitable turbine type for the mini-hydro power of run off river in the Konang river, and to analyze the power and energy based on the single and plural Flow Duration Curve (FDC). The result can be applied on the design of run off river mini-hydro power in the Konang river, Trenggalek regency-Indonesia, By the treatment, it is hoped to be able to produce the significant decreasing of mini-hydro power energy.
