Performance tests and evaluation of hydropower plant with double rotating hydropower screw system

Abstract

The newly developed Archimedean double screw hydropower concept combines hydroelectric power generation and bi-directional fish passage in a single device. Efficiency tests were conducted at the first commercial facility to verify the design data. The downstream migration possibilities have previously been proven. However, this study demonstrates the operational capability for upstream migration. The hydraulic efficiency of this type of power plant is also determined. This is the first time that the hydraulic performance of this type of plant has been demonstrated.
