Sažetak
Various EU regulations have established rules for accessing the electricity exchange grid in order to ensure proper functioning of the electricity market while maintaining a proper level of system security. System security depends on the technical capabilities of its components to withstand disturbances and to help prevent serious interruptions or to re-establish system operation after a breakdown occurs. U radu su dana teorijska razmatranja i osvrti na Plan obrane od velikih poremećaja. U središte analize su stavljeni regulaciju napona transformatora, mogućnost preopterećenja elementa mreže, učinci blokade regulatora i ukupnost pozitivnih učinaka na očuvanje sigurnosti sustava. This paper generally gives a theoretical and practical overview of measures for the automatized protection against voltage disruption and reduction of the active or reactive load of lines or transformers in the subsystem PrP Osijek. For this purpose, the possibility of using different protection and automation devices will be analyzed to preserve the basic contour of the transmission grid in order to quickly establish consumer power supply and normal system operation. In addition to automatic protection, measures of excluding certain elements of the grid will be shown, as well as functions for blocking/activating the regulation of grid elements in order to reduce active and reactive loads of lines or transformers. The analysis gives the effect of some measurements on a real transmission grid model. The model had to be adjusted with the grid state and load requirements that anticipated various unfavorable scenarios which could cause the power system to break down.
