Discharge Simulation as Potential Energy of Sibundong Hydroelectric Power Plant

摘要

In the planning of hydroelectric power plant requires sufficient discharge data for the purpose of hydrological analysis of the watershed. In the Sibundong watershed encountered incomplete discharge measurement problems, many empty discharge observations, and prolonged discharge data. With the tank model, it is expected to be able to perform a discharge simulation to find out the amount of discharge in the river. The purpose of this study is to apply the tank model in the estimation of river discharge and calculate the dependable discharge on the Sibundong river, in addition, it is also to analyze the potential power of Sibundong hydroelectric power plant. From the result of generator discharge analysis, it can be analyzed the probability of discharge reliability based on Flow Duration Curve that is Q = 9.29 m3/s, P = 60%. Selected Francis turbine has a sensitivity of operating variation from 35% to 105% of the discharge design of generator, the turbine operating discharge pattern is between 60% and 100% with consideration of dependable discharge. The power potential that can be generated for the hydroelectric power operation pattern is 2 x 6.26 MW and the energy is 1489.96 GWh/year.
