Using A Simple Technique To Economic Feasibility And Assess The Technical Of Micro Hydro Power Plants In Existing Watering Systems

摘要

A humble technique is suggested to spot turbines and pick their rule output, appraise charges and revenues and offer useful indications for Micro Hydro Power (MHP) plant project in current irrigation systems.This technique, based on simple models and demanding a reduced number of input factors cool to survey in primary project stages, has been used and confirmed in an existing irrigation system located in Calabria (Italy).The consequences have emphasized that in the case study the lowest profitable turbine would yield5 KW. A lower number of plants (with higher output) would create no particular monetary savings compared to a greater number of smaller turbines. Besides, neither was the choice of increasing pipe diameter found to provide savings. In general, a considerable potential from MHP operation has been revealed in current irrigation systems, providing a return on investment higher than that provided by the Italian monetary market.Lastly, MHP usefulness noticeably rises with total annual process time, being on average 55%higher in a wet year (eight months of electrical production/four month of irrigation) as opposed to a dry year (six months of electrical production/six months of irrigation).
