Title Requirements for the connection of micro-generators in parallel with public low-voltage distribution networks
Project Number 22109
Abstract/Scope This European Standard specifies technical requirements for connection and operation of fixed installed micro-generators and their protection devices, irrespective of the micro-generators primary source of energy, in parallel with public low-voltage distribution networks, where micro-generation refers to equipment rated up to and including 16 A per phase, single or multi phase 230/400 V or multi phase 230 V (phase-to-phase voltage). In some countries this document may be applied to generators with higher ratings used mostly in domestic and small commercial installations. These countries are listed in Annex F. Whenever the scope is extended to equipment rated greater than 16 A per phase additional standards could be applicable. The electrical interface is the principal focus and this includes the method of connection, the settings and protection requirements for connection, the operation of the electrical interface under normal conditions, emergency shutdown, distribution network-independent operation, start-up and distribution network synchronisation. The provisions of this European Standard are not intended to ensure by themselves the safety of DNO personnel or their contracted parties. The intention of this European Standard is to ensure that the micro-generator satisfies appropriate provisions for • the requirements of the DNO, • information to electricians working in the electrical installation • quality of supply. The following aspects are included in the scope: • all micro-generation technologies are applicable. The following aspects are excluded from the scope: • multiple units that for one installation, in aggregate, exceed 16 A; • issues of revenue rebalancing, metering or other commercial matters; • generators never working in parallel with the public low-voltage distribution network; • requirements related to the primary energy source e.g. matters related to gas fired generator units; • intended network independent operation. NOTE If independent operation is intended, generally preliminary agreement of the DNO shall be obtained, however this is out of the scope of this document. Specific additional requirements most likely could be applicable.

Normative reference (6)  

(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved


(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat


(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level


(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement


(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn


(6) This list of normative references is purely indicative. The only official list of normative reference is the list of the published standard.
