SIST EN 50549-1:2019

Requirements for generating plants to be connected in parallel with distribution networks - Part 1: Connection to a LV distribution network - Generating plants up to and including Type B

These standards provide technical requirements for the connection of generating plants up to and including Type A (-1-1)/ Type B (-1-2) which can be operated in parallel with a public LV distribution network. They are intended to be used as a technical reference for connection agreements between DNOs and electricity producers and to demonstrate compliance with COMMISSION REGULATION (EU) 2016/631 (Requirements for Generators).

Anforderungen für zum Parallelbetrieb mit einem Verteilnetz vorgesehene Erzeugungsanlagen - Teil 1: Anschluss an das Niederspannungsverteilnetz bis einschließlich Typ B

Exigences relatives aux centrales électriques destinées à être raccordées en parallèle à des réseaux de distribution - Partie 1: Raccordement à un réseau de distribution BT - Centrales électriques jusqu’au Type B inclus

Zahteve za vzporedno vezavo generatorskih postrojev z razdelilnim omrežjem - 1. del: Vezava z nizkonapetostnim razdelilnim omrežjem - Generatorski postroji do vključno tipa B

Ti standardi podajajo tehnične zahteve za povezovanje generatorskih postrojev do vključno tipa A (-1-1)/tipa B (-1-2), ki jih je mogoče upravljati vzporedno z javnim nizkonapetostnim razdelilnim omrežjem. Namen njihove uporabe je tehnična referenca za dogovore o priključku med upravljavci razdelilnih omrežij in proizvajalci električne energije ter izkazovanje skladnosti z UREDBO KOMISIJE (EU) 2016/631 (Zahteve za generatorje).

SIST EN 50549-1 : 2019

NACIONALNI UVOD

Standard SIST EN 50549-1 (sl), Zahteve za vzporedno vezavo generatorskih postrojev z razdelilnim
omrežjem – 1. del: Vezava z nizkonapetostnim razdelilnim omrežjem – Generatorski postroji do vključno
tipa B, 2019, ima status slovenskega standarda in je istoveten evropskemu standardu EN 50549-1 (en),
Requirements for generating plants to be connected in parallel with distribution networks – Part 1:
Connection to a LV distribution network – Generating plants up to and including Type B, 2019.

Ta standard nadomešča SIST-TS CLC/TS 50549-1:2015.

NACIONALNI PREDGOVOR

Evropski standard EN 50549-1:2019 je pripravil tehnični odbor Evropskega komiteja za standardizacijo
v elektrotehniki CLC/TC 8X Sistemski vidiki oskrbe z električno energijo.

Slovenski standard SIST EN 50549-1:2019 je prevod evropskega standarda EN 50549-1:2019. V
primeru spora glede besedila slovenskega prevoda v tem standardu je odločilen izvirni evropski
standard v angleškem jeziku. Slovensko izdajo standarda je pripravil tehnični odbor SIST/NTF Oskrba
z električno energijo.

Odločitev za privzem tega standarda je v marcu 2019 sprejel tehnični odbor SIST/TC NTF Oskrba z
električno energijo.

ZVEZE S STANDARDI

S privzemom tega evropskega standarda veljajo za omejeni namen referenčnih standardov vsi
standardi, navedeni v izvirniku, razen standarda, ki je že sprejet v nacionalno standardizacijo:

SIST EN 50549-2 Zahteve za vzporedno vezavo generatorskih postrojev z razdelilnim omrežjem
– 2. del: Vezava s srednjenapetostnim razdelilnim omrežjem do vključno tipa
B
SIST EN 60255-127 Merilni releji in zaščitna oprema - 127. del: Funkcijske zahteve za pre- in
podnapetostno zaščito (IEC 60255-127)
SIST EN 61000-4-30 Elektromagnetna združljivost (EMC) - 4-30. del: Preskusne in merilne tehnike
- Metode merjenja kakovosti napetosti (IEC 61000-4-30)
SIST HD 60364-1 Nizkonapetostne električne inštalacije - 1. del: Temeljna načela, ocena
splošnih karakteristik, definicije
SIST HD 60364-5-551 Nizkonapetostne električne inštalacije - 5-55. del: Izbira in namestitev
električne opreme - Druga oprema - 551. točka: Nizkonapetostni generatorji

OSNOVA ZA IZDAJO STANDARDA

– privzem standarda EN 50549-1:2019

PREDHODNA IZDAJA

– SIST-TS CLC/TS 50549-1:2015, Zahteve za priklop generatorjev za toke nad 16 A na fazo – 1. del:
Priklop na nizkonapetostni distribucijski sistem

OPOMBE

– Povsod, kjer se v besedilu standarda uporablja izraz “evropski standard”, v SIST EN 50549-1:2019
to pomeni “slovenski standard”.

– Nacionalni uvod in nacionalni predgovor nista sestavni del standarda.
