Abstract

Elektrodistributivna mreža osim osnovnog signala sadrži i mnoge poremećaje kao što su harmonici, promjene frekvencije, skokovi, prijelazne promjene itd. U sklopu ovog Završnog rada napravio se teorijski pregled nekih od tih poremećaja u skladu s normom EN 50160. Opisani su prekidi opskrbnog napona, propadi, nadvišenja te tranzijentni prenaponi u svrhu stvaranja simulatora signala koji će kasnije poslužiti u daljnjoj analizi, a u svrhu poboljšanja upravljanja sustavima za kontrolu kvalitete električne energije. Prikazana je jednostavna blok shema simulatora signala navedenih poremećaja, a sam simulator je opisan u programskom okruženju MATLAB radi što zornijeg prikaza navedenih poremećaja. Testna funkcija unutar programskog koda opisuje osnovni signal te svaki od poremećaja zasebno. Preklapanja poremećaja su itekako moguća u stvarnim mrežnim prilikama, ali za potrebe ovog Završnog rada programski kod je pisan jednostavnije tako što je pretpostavljeno da se svaki poremećaj događa u zasebnom vremenskom intervalu.

Abstract (english)

In addition to the basic signal in the supply network there are many disturbances such as harmonics, frequency changes, jumps, transient changes, etc. Within this Final paper theoretical review of some of these disturbances has been made in accordance with EN 50160. For the purpose of generating a signal simulator that will later serve in further analysis to improve the management of power quality control systems a description of the supply voltage interruptions, surges, swells and transient overvoltages is given. A simple block diagram of the signal simulator of the above-mentioned disorders is shown and the simulator is described in the MATLAB programming environment because it can provide a detailed description of the disturbances. The test function within the program code describes the basic signal and each of the disturbances separately. Overlapping of the disturbances is very often in a real-world network but for the purpose of this Final paper, the program code has been written in a simpler fashion by assuming that each disorder occurs in a separate time interval.
