| Title | Requirements for the connection of generators above 16 A per phase - Part 1: Connection to the LV distribution system |
| Project Number | 20863 |
| Abstract/Scope | The purpose of this Technical Specification is to provide technical guidance for the connection of generating plants which can be operated in parallel with a public distribution network. This Technical Specification is intended to be used as a technical reference in connection agreements between DNOs and electricity producers. The requirements of this Technical Specification only apply to electrical machinery and equipment, irrespective of the kind of primary energy source. This Technical Specification applies to all three-phase generating units that meet all of the following conditions as an individual generating unit or as a cluster of generating units with a common point of connection: • converting any primary energy source into AC electricity; • connected to the LV network and rated at more than 16A per phase; • intended to operate in parallel with a public distribution network under normal network operating conditions. NOTE Generators rated up to and including 16A per phase are covered by EN 50438. This Technical Specification defines interconnection requirements and a conformance test procedure. Island operation of generating plants, both intentional and unintentional, where no part of the public distribution system is involved is out of the scope of this Technical Specification. Safety of personnel is out of the scope of this Technical Specification. This Technical Specification recognises the existence of National Standards and Network Codes: these must be complied with. Only in the absence of these National Standards and Codes should the requirements of this Technical Specification be applied. |

(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.
