(Main)Requirements for generating plants to be connected in parallel with distribution networks - Part 10: Tests for conformity assessment of generating units
Requirements for generating plants to be connected in parallel with distribution networks - Part 10: Tests for conformity assessment of generating units
The purpose of this document is to provide technical guidance for tests on generating units and interface protection to evaluate their electrical characteristics.
NOTE 1 Mechanical issues are taken into account as far as they influence the electrical characteristics.
The evaluation results are intended to be used to demonstrate conformity of generating units to technical requirements for grid connection. In this context the evaluation results can also be used as part of a certification programme.
NOTE 2 Besides the type test results of the generating unit all additional elements for connection to the grid (e.g. transformer, cabling, multiple units) are considered in the evaluation of the final installation of a generating plant.
The requirements to be evaluated are covered in the following standardization documents:
– 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
– EN 50549 2:2019: Requirements for generating plants to be connected in parallel with distribution networks - Part 2: Connection to a MV distribution network - Generating plants up to and including Type B
If grid connection requirements are dealt with in other documents or for other generating module types, where no specific testing procedure is provided, testing methods of this document can be used if applicable.
This document provides evaluation criteria for the conformity assessment of generating units with respect to the above mentioned standardization documents, based on type testing. However, some requirements are applicable on the generating plant level. The assessment of the conformity to these plant requirements are out of the scope of this document. Nevertheless, this document may be used to show the capabilities of a generating unit to be used in a plant.
As a consequence, it is possible that the conformity assessment of a generating unit does not cover all aspects of the above-mentioned standardization documents, typically when a requirement is evaluated on a plant level. Therefore, the conformity assessment report indicates clearly which clauses of this document are covered and which clauses are not covered.
This document recognizes the existence of specific technical test requirements within several member states that must be complied with.
Anforderungen für zum Parallelbetrieb mit einem Verteilnetz vorgesehene Erzeugungsanlagen - Teil 10: Tests für die Konformitätsbeurteilung von Erzeugungseinheiten
Exigences relatives aux centrales électriques destinées à être raccordées en parallèle à des réseaux de distribution - Partie 10: Essais d’évaluation de la conformité des unités de production
L’objectif du présent document est de fournir des recommandations techniques pour les essais sur les unités de production et la protection de découplage afin d’évaluer leurs caractéristiques électriques.
NOTE 1 Les problèmes mécaniques sont pris en compte dans la mesure où ils influencent les caractéristiques électriques.
Les résultats d’évaluation sont destinés à démontrer la conformité des unités de production aux exigences techniques de raccordement au réseau. Dans ce contexte, les résultats de l’évaluation peuvent également être utilisés dans le cadre d’un programme de certification.
NOTE 2 Outre les résultats des essais de type de l’unité de production, tous les éléments supplémentaires servant au raccordement au réseau électrique (par exemple, transformateur, câblage, unités multiples) sont pris en compte dans l’évaluation de l’installation finale d’une centrale.
Les exigences à évaluer sont couvertes par les documents de normalisation suivants:
– EN 50549 1:2019: 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
– EN 50549 2:2019: Exigences relatives aux centrales électriques destinées à être raccordées en parallèle à des réseaux de distribution — Partie 2: Raccordement à un réseau de distribution MT — Centrales électriques jusqu’au Type B inclus
Si les exigences de raccordement au réseau sont traitées dans d’autres documents ou pour d’autres types de modules de production, où aucune procédure d’essai spécifique n’est prévue, les méthodes d’essai du présent document peuvent, le cas échéant, être utilisées.
Le présent document fournit des critères d’évaluation pour l’évaluation de la conformité des unités de production par rapport aux documents de normalisation susmentionnés, sur la base d’essais de type. En revanche, certaines exigences s’appliquent au niveau de la centrale. L’évaluation de la conformité à ces exigences ne relève pas du domaine d’application du présent document. Néanmoins, ce dernier peut être utilisé pour montrer les capacités d’utilisation d’une unité de production dans une centrale.
Par conséquent, il est possible que l’évaluation de la conformité d’une unité de production ne couvre pas tous les aspects des documents de normalisation susmentionnés, notamment lorsqu’une exigence est évaluée au niveau d’une centrale. Le rapport d’évaluation de la conformité indique donc clairement quels articles du présent document sont couverts et lesquels ne le sont pas.
Le présent document reconnaît l’existence, dans plusieurs Etats membres, d’exigences techniques spécifiques en matière d’essais qui doivent être respectées.
Zahteve za vzporedno vezavo generatorskih postrojev z javnim nizkonapetostnim razdelilnim omrežjem - 10. del: Preskusi za oceno skladnosti generatorskih enot
Namen tega dokumenta je podati tehnična navodila za preskuse v zvezi z zaščito generatorskih enot in vmesnikov, da se ovrednotijo njihove električne značilnosti.
OPOMBA 1: Mehanske težave so upoštevane, v kolikor vplivajo na električne značilnosti.
Rezultati vrednotenja so namenjeni dokazovanju skladnosti generatorskih enot s tehničnimi zahtevami za omrežno vezavo. V tem kontekstu je mogoče rezultate vrednotenja uporabiti tudi kot del programa certificiranja.
OPOMBA 2: Pri vrednotenju končne namestitve generatorskega postroja se poleg rezultatov tipskega preskusa generatorske enote upoštevajo tudi vsi dodatni elementi za vezavo z omrežjem (npr. transformator, kabli, večdelne enote).
Zahteve, ki jih je treba ovrednotiti, so zajete v naslednjih dokumentih za standardizacijo:
– EN 50549-1:2019: Zahteve za vzporedno vezavo generatorskih postrojev z javnim nizkonapetostnim razdelilnim omrežjem – 1. del: Vezava z nizkonapetostnim razdelilnim omrežjem – Generatorski postroji do vključno tipa B
– EN 50549-2:2019: Zahteve za vzporedno vezavo generatorskih postrojev z javnim nizkonapetostnim razdelilnim omrežjem – 2. del: Vezava s srednjenapetostnim razdelilnim omrežjem – Generatorski postroji do vključno tipa B
Če so zahteve glede vezave z omrežjem obravnavane v drugih dokumentih ali za druge tipe generatorskih modulov, v katerih določen preskusni postopke ni podan, je mogoče uporabiti preskusne metode iz tega dokumenta, če je primerno.
Ta dokument podaja merila vrednotenja za oceno skladnosti generatorskih enot z zgoraj omenjenimi dokumenti za standardizacijo na podlagi tipskega preskušanja. Vendar se nekatere zahteve uporabljajo na ravni generatorskega postroja. Ocena skladnosti s temi zahtevami za postroje ne spada na področje uporabe tega dokumenta. Kljub temu se lahko ta dokument uporabi za prikaz zmogljivosti generatorske enote, ki bo uporabljena v postroju.
Posledično je možno, da ocena skladnosti generatorske enote ne zajema vseh vidikov zgoraj omenjenih dokumentov za standardizacijo, kar je običajno v primeru ocenjevanja zahteve na ravni postroja. Zato je v poročilu o oceni skladnosti jasno navedeno, katere točke tega dokumenta so oziroma niso zajete.
Ta dokument priznava obstoj posebnih zahtev za tehnične preskuse v več državah članicah, ki jih je treba upoštevati.

European foreword
This document (EN 50549-10:2022) has been prepared by CLC/TC 8X “System aspects of electrical energy
supply”.
The following dates are fixed:
• latest date by which this document has to be (dop) 2023-08-09
implemented at national level by publication of
an identical national standard or by
endorsement
• latest date by which the national standards (dow) 2025-08-09
conflicting with this document have to be
withdrawn
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. CENELEC shall not be held responsible for identifying any or all such patent rights.
EN 50438:2013 has been superseded by EN 50549-1:2019. However, Annex D of EN 50438:2013 provided
requirements on compliance type testing, which is out of the scope of EN 50549-1:2019 resulting in a gap
regarding type testing. This document provides requirements for compliance type testing for generating units
and closes this gap.
This document has been prepared under a Standardization Request given to CENELEC by the European
Commission and the European Free Trade Association.
Any feedback and questions on this document should be directed to the users’ national committee. A complete
listing of these bodies can be found on the CENELEC website.

1 Scope
The purpose of this document is to provide technical guidance for tests on generating units and interface
protection to evaluate their electrical characteristics.
NOTE 1 Mechanical issues are taken into account as far as they influence the electrical characteristics.
The evaluation results are intended to be used to demonstrate conformity of generating units to technical
requirements for grid connection. In this context the evaluation results can also be used as part of a certification
programme.
NOTE 2 Besides the type test results of the generating unit all additional elements for connection to the grid (e.g.
transformer, cabling, multiple units) are considered in the evaluation of the final installation of a generating plant.
The requirements to be evaluated are covered in the following standardization documents:
– 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
– EN 50549-2:2019: Requirements for generating plants to be connected in parallel with distribution networks
- Part 2: Connection to a MV distribution network - Generating plants up to and including Type B
If grid connection requirements are dealt with in other documents or for other generating module types, where
no specific testing procedure is provided, testing methods of this document can be used if applicable.
This document provides evaluation criteria for the conformity assessment of generating units with respect to the
abovementioned standardization documents, based on type testing. However, some requirements are
applicable on the generating plant level. The assessment of the conformity to these plant requirements are out
of the scope of this document. Nevertheless, this document may be used to show the capabilities of a generating
unit to be used in a plant.
As a consequence, it is possible that the conformity assessment of a generating unit does not cover all aspects
of the above-mentioned standardization documents, typically when a requirement is evaluated on a plant level.
Therefore, the conformity assessment report indicates clearly which clauses of this document are covered and
which clauses are not covered.
This document recognizes the existence of specific technical test requirements within several member states
that must be complied with.
