ANALYSIS OF HYDRO POWER PLANT BY THE HILL-CHART DIAGRAM
KOMUNALNA ENERGETIKA / POWER ENGINERING, 3
In the paper the operational analysis of hydro power plant is represented. The turbine model, as one of the main part in hydro power plant, is obtained by the hill-chart diagram of the turbine. The whole model is built in program package Matlab/Simulink. The operational analysis of the hydro power plant is performed at the hill-chart basis regards on any flow and head, whilst the output parameters of model are turbine efficiency and power. The proposed model can be used as useful tool in the different operational regime estimation, even within the optimization algorithms.

ACCEPTANCE INDICATORS OF A MICRO HYDRO POWER PLANT INVESTMENT FOR A MICRO HYDRO POWER PLANT "KOTNIK"
KOMUNALNA ENERGETIKA / POWER ENGINERING, 5
This paper deals with the impact of the energy cost, produced by a micro hydro power plant, on the acceptance indicators of a micro hydro power plant investment. The aforementioned acceptance indicators are the net present value and the internal rate of return. All calculations are performed for a micro hydro power plant "Kotnik" with power of 10 kW, where technical and essentially financial parts are observed.
