This standard specifies the technical requirements for the connection and operation of micro- cogenerators 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, voltage 230/400 V. This standard prescribes a "Fit and inform" procedure, due to the small capacity and type certification. 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. For the electrical installation this standard makes reference to HD 384 series and in HD 384.5 series "Selection and erection of electrical equipment.. Requirements for automatic disconnection and isolation regulations for safety purposes are included, however the standard does not cover the safety of DNO personnel or their contracted parties, as their safety is a combination of the electrical conditions and working instructions, which is the responsibility of the DNO. The intention of this standard is to ensure that micro-cogenerator satisfies appropriate provisions for - safety of persons, - the requirements of the DNO e.g. grid protection, - information to electricians working inside the house, - quality of supply, - electrical protection of the generation unit. The following aspects are included in the scope: - all micro-generation technologies are applicable; - intended grid independent operation, however guidance on how to transfer from parallel operation to grid independent operation and back again is under consideration. The following aspects are excluded from the scope: - multiple units that exceed 16 A per phase in aggregate, for one installation; - issues of revenue rebalancing, metering or other commercial matters; - cogenerators never to be connected to the supply networks; - requirements related to the primary energy source e.g. matters related to gas fired cogenerator units.
