Abstract

Električno omrežje sestavljajo naprave, ki potrebujejo za svoje delovanje jalovo moč. Za zmanjšanje izgub, ki so povezane s prenosom energije, uporabljamo naprave za kompenzacijo jalove moči. V diplomi imamo opraviti s kombiniranim bremenom, ki je sestavljeno iz bremen s počasnim dinamičnim odzivom in bremen s hitrim dinamičnim odzivom. Avtomatska kompenzacijska naprava je uporabljena za kompenzacijo jalove moči bremen s počasnim dinamičnim odzivom, dinamična kompenzacijska naprava pa za kompenzacijo jalove moči bremen s hitrim dinamičnim odzivom. Analiza izvedena v diplomski nalogi temelji na simulacijskih izračunih izvedenih v programskem paketu Matlab-Simulink in na rezultatih meritev na terenu. V obeh primerih je jasno razvidno, da kompenzacijska naprava bistveno zmanjša jalovo moč dobljeno iz omrežja. Po vključitvi naprave za kompenzacijo jalove moči se pri enaki delovni moči bremena bistveno zmanjša efektivna vrednost bremenskega toka.

Secondary title:	Power factor correction device
Secondary abstract:	Electricity network mostly consists of devices which require reactive power for their operation. In order to minimize losses related with energy transmission reactive power compensation, in the form of a power factor correction device, can be introduced. The diploma thesis deals with the combined load, composed of the load with slow dynamic response and the load with fast dynamic response. An automatic power factor correction device is applied to compensate reactive power of the load with slow dynamic response while a dynamic power factor correction device is used to compensate reactive power in the case of the load with fast dynamic response. The analysis performed in the diploma thesis is based on simulations performed in the program package Matlab-Simulink and on the results of field testing. In both cases, it is clearly shown that the power factor correction device substantially reduces reactive power delivered from the grid. After switching-on the power factor correction devices, the load current rms vale decreases substantial at the same active power of the load.
