Abstract: It is demonstrated with applications, that the use of a computer-aided preliminary optimization model can help evaluate the overall technical and economic characteristics of low-head hydro installations. The model can provide realistic information on the optimum operational ranges of impulse, reaction and crossflow turbines, as well as the relevant discharge, power output and cost characteristics for various alternative scenarios. The program LOHED analyzes discharge/gross head data to predict available power for a variety of different penstock sizes. It also selects preliminary turbine characteristics based on actual data gathered from various turbine manufacturers. The program FINAN uses the output from LOHED along with some initial cost data for specific equipment and materials, synthesizes a cashflow over the life of the project, and amoritizes it to a present value.
