Abstract

U svijetu ubrzanog rasta stanovništva i tehnologije,povećava se potreba za čistom energijom. Najbrža rastuća elektrana na obnovljive izvore je vjetroelekrana. Da bi isporučena energija doprinijela stabilnosti i sigurnosti prijenosnog i distribucijskog sustava potrebno ju je zaštiti. U radu je opisana relejna zaštita kojom se postiže siguran rad vjetroagregata. Istraženi su problemi s kojima se zaštite susreću u praksi bilo da je kvar na vjetroelektrani ili na mreži na kojoj je spojena. Da bi se smanjili utjecaji udara munje na opremu i ljude koristi se zaštita od udara munje. Ona mora biti dobro izvedena jer amplituda struje udara u kratkom vremenu postiže veliki iznos. Također je i uzemljenje vjetroelektrane, koje ima ulogu odvođenja visokog prenapona i struje, obrađeno u radu.

Abstract (english)

In a world of rapid population and technology growth, the need for clean energy is increased. The fastest growing plants on renewable sources is wind plants. delivered energy which contribute to the stability and security of the transmission and distribution system needs to be protected. The paper describes the relay protection, which makes the safe operation of the wind turbine. In paper are explored problems which protections of wind power plant face in practice, no matter if failure is internal or external. In order to reduce the effects of lightning on equipment and personnel, lightning protections is used. It must be well executed because the amplitude of the lightning current in a short time achieved a huge amount. Also, a grounding of wind power plant, which has the role of taking the high voltage and current, is discussed in the work.
