Abstract
Svrha ovog diplomskog rada bilo je analizirati potencijalni utjecaj određenih parametara kvalitete električne energije na uređaje zaštite u 10 kV distribucijskoj mreži. Navedeni su osnovni parametri norme EN 50160, te osnovne zadaće i tipovi relejne zaštite. Zatim se definiraju utjecaji određenog tipa poremećaja na instaliranu relejnu zaštitu te utjecaj smetnji na rad releja. Vrši se detaljnija kvantifikacija poremećaja u elektroenergetskom sustavu i njihov utjecaj na zone postavljanja releja. Nakon toga rade se studije slučaja te teorijske i grafičke analize utjecaja pojedinih događaja na relej. Prikazuju se odzivi različitih vrsta filtara releja na različite događaje u mreži. U zadnjem poglavlju radi se računska analiza utjecaja efekata nesinusoidalnih struja na elektromehanički nadstrujni relej i digitalni upravljački relej motora.
Abstract (english)
The purpose of this Master´s thesis was to analyze the potential impact of certain parameters of power quality on the protection devices in the 10 kV distribution network. The basic parameters of EN 50160 are listed, as well as basic tasks and types of relay protection. Then the impact of a certain type of disturbance on the installed relay protection and the impact of interference on the relay operation are defined. A more detailed quantification of disturbances in the power system and their impact on the relay setting zones is performed. After this, case studies are performed, as well as theoretical and graphical analysis of the influence of certain events on the relay. Responses of different types of relay filters to different events in the network are displayed. In the last chapter, a calculation analysis of the effect of non-sinusoidal current effects on the electromechanical overcurrent relay and the digital motor menagement relay is performed.
