Abstract
This article deals with the design optimization of the micro-hydropower plant. This mini-power source is designed as an additional power source for small recreational objects or remote places with access to a water stream of flow rate approximately 0.4 m3/s. A paddle wheel with 3 m diameter is welded from sheet metal. The paddle wheel is designed for a rotational speed of 5 rpm. The electric generator with planetary gear is integrated into central supported tube. The original construction was very robust and heavy. Particularly due to the high weight, it was required optimizing of design. A finite element model of the whole structure of the hydropower plant was created. Mechanical stresses and deformations in main part have been analyzed. Based on these analyzes, optimization has been proposed with the result of weight reduction while maintaining of use properties and with good durability.
