This diploma thesis deals with the design of hydraulic cleaning machine of fine screens located in the supply channel of small hydropower plant. The part of this thesis is also the design of hydraulic circuit and strength analysis using finite element method. The thesis also deals with the optimal debris removal. The thesis is attached by drawing documentation of selected parts of the mechanism.

This thesis focused on creating a model of a small hydropower plant model (SHPP) and a part of the electricity network in the simulation software "PSCAD" (basing on real sources). The model will be specified on the basis of the data obtained from the measurements to correspond with the real equipment.
