Abstract

Ovim radom je realizirana estimacija potrošnje energije u prostorijama sjeverne
strane devetog kata Fakulteta elektrotehnike i racunarstva Sveucilišta u Zagrebu. Estimacijski postupak izvršen je putem nederivacijskog Kalman filtra. Za potrebe estimacije razvijen je hidraulicki i temperaturni model razmatranog sustava centralnog grijanja u Matlab/Simulink programskom okruženju. Upravljanje protokom kroz ventilokonvektore ostvarano je pomocu troputnog ventila. Estimacijom se odrežuju parametri hidraulickog modela sustava kako bi se potom korištenjem takvog modela mogla procjenjivati snaga ventilokonvektora u radu.

Abstract (english)

This thesis realized energy consumption estimation in rooms on the north side of
the ninth floor of the Faculty of Electrical Engineering and Computing University of
Zagreb. Estimation process is done using Unscented Kalman filter. For estimation
needs, hydaulic and temperature model of the considered central heating system is
derived using Matlab/Simulink environment. Flow control is realized with a three-way
valve utilization. Estimation of the hydraulic model parameters is done so that such
could provide a model convenient for evaluating the power of fan coils in operation.
