Abstract
Regulacija napona i jalove snage u elektroenergetskom sustavu ističe se kao glavni način očuvanja naponske stabilnosti. Iako je prisutnost jalove snage u sustavu povezana s gubicima, tj. padovima napona na reaktivnim elementima mreže, u drugu ruku je iznimno korisna za regulaciju napona, ali i potrebna industrijskim potrošačima. Uspoređujući izmjerenu vrijednost na izlazu iz regulacijskog uređaja s referentnom vrijednošću na ulazu u regulator, regulatori napona i jalove snage reagiraju na promjene u mreži. Hijerarhijski je sustav regulacije podjeljen na primarnu, sekundarnu i tercijarnu. Regulacija je poredana od najužeg (lokacijskog) do najšireg (globalnog) djelovanja za promatrani EES. U budućnosti se očekuje veća upotreba statičkih naprava za kompenzaciju jalove snage temeljenim na energetskoj elektronici, a time i veći prijenosni kapacitet sustava s povećavanjem njegove sigurnosti i pouzdanosti.

Parallel abstract (English)
The best method for keeping the voltage stability is using the voltage and reactive power control in the electrical power systems. Although reactive power flow in the system is related with power losses and voltage drops respectively, it's very useful for controlling the voltage rate in its limits but is also required from industrial loads. Comparing the output voltage values of the regulating devices to some actual fixed reference value on the regulator's input, regulators react to the changes in the power system. Hierarchical system of controlling the voltage and reactive power is divided into three controlling circuits. These are primary, secundary and tertiary, established from the narrowest (local) to the widest (global) control of the system. In the future of reactive power and voltage control, new regulation methods are expected, considering static resources that belong to power electronics-based systems. Usage of so called FACTS devices will increse security and reliability, as well as transmission capacity of its electrical power grid
