Feasibility of a Cascade Type Hydroelectric Generator System

Abstract

<p>The feasibility of an alternative concept of a small scale hydroelectricity generation system which is suited to high volume, low head flows was investigated. The device consists of a cascade of hydrofoils which are mounted in an arrangement which resembles a conveyor belt. The investigation included the use of a computer model which simulated the water flow through the cascade. A sensitivity analysis was done using the model to establish the effects of varying the design variables which defined the system. On the basis of the analysis, a prototype was designed with the consideration of the material, configuration, safety and environmental requirements. A cost estimate and economic analysis were made of the prototype and subsequently the concept was evaluated.</p>
