MATHEMATICAL MODEL FOR CATHODIC PROTECTION OF THE UNDERGROUND PIPELINES
KOMUNALNA ENERGETIKA / POWER ENGINERING, 22
Cathodic protection is most often used technique for protection of underground or underwater metallic infrastructure from corrosion. Design of the cathodic protection system implies determination of the potential distribution on the protected object surface which meets given criterions. This paper presents a mathematical model for calculating cathodic protection system parameters. Presented mathematical model was used to conduct the analysis of the impact of soil resistivity and coating resistivity on the level of polarization.

MATHEMATICAL MODEL OF SOLAR CELL COMPOSED IN MATLAB/SIMULINK
KOMUNALNA ENERGETIKA / POWER ENGINERING, 30
This article presents a mathematical model of solar cell composed in Matlab/Simulink. Mathematical models of solar cell presented in the article are differ in the complexity of the structure and consequently the accuracy of the responses to the input parameters and they are named as ideal, simple, single-diode and two-diode model. In Matlab/Simulink are mathematical models of solar cell assembled with the help of terms, which describe the operation of solar cell. We compared mathematical models of solar cell with each other and we were evaluated them by comparing with the measured values of the actual solar cell.

MATHEMATICAL MODEL OF SOLAR POWER PLANT BRESTANICA
KOMUNALNA ENERGETIKA / POWER ENGINERING, 31
This article presents a mathematical model of solar power plant composed of Matlab/Simulink. For the evaluation of simulation results of the mathematical model of the solar power plant we use the results of measurements from the actual solar power plant Termoelektrarna Brestanica d. o. o. We evaluate the results of simulation calculations and measurements of the actual plant for different days of the year. The results show good correlation between calculated and measured values of solar power, which is a good basis for further use of mathematical model of solar power for the analysis of voltage profiles of the network.
