Abstract

Generator je jedan od najbitnijih elemenata u elektroenergetskom sustavu. To je uređaj koji u elektrani iz mehaničke energije proizvodi električnu energiju. Zbog njegove uloge i velike cijene potreban mu je složeni sustav zaštite kako bi spriječili oštećenja uzrokovana kvarovima i smetnjama u radu. Tu zaštitu postižemo složenom uporabom zaštitnih releja. Oni služe kako bi na vrijeme otkrili probleme i na iste pravilno reagirali. Zaštitni releji iako zahtijevaju nešto veća početna ulaganja dugoročno donose uštede i sigurnost radu generatora. U ovom radu su razmotreni mogući poremećaji u normalnom radu generatora i problematika vezana za njegovu zaštitu od smetnji i nenormalnih pogonskih stanja. Također opisan je zaštitni uređaj koji štiti sinkroni generator.

Abstract (english)

Generator is considered one of the most important elements in power systems. Generator is a device located in a power plant with a single duty, to convert mechanical energy to elecrtical energy. It's function and price in general make it necessary to apply a complex protection system in order to prevent faults and abonrmal operational hazards. That kind of protection is achieved using protection relays. Their function is quick fault and disturbance discovery. Inital investment is required but they reduce the longterm cost and generate stability. In this paper we study generator faults and operational hazards and setting a sucssful generator protection. Such generator protection device is also described.
