Development and Dissemination of Ecotype Hydraulic Turbines

Abstract

Ecotype hydraulic turbines can be utilized small and distributed water resources with little civil engineering works and without environmental burdens. In Japan, network of agricultural waterway extends 400 thousands kilometers, this abundance of waterpower has a high expectations for electric power generation to supply to agricultural facilities. This promotes local production for local consumption of electricity. Four types of turbine, Savonius turbine, waterfall turbine, jet turbine and undershot turbine, were investigated and demonstrated in some fields. We have been also investigated the standalone smart grid system which can harness a several types of ecotype turbines. It can control the amount of generation power and supplying electricity. In this manuscript, we summarize our results of the investigation of ecotype hydraulic turbines.
