DIN EN 62116:2012-01

The purpose of this European Standard is to describe a test procedure to evaluate the performance of islanding prevention measures used with utility-interconnected PV systems. This standard does not specify settings parameters (voltage and frequency trip magnitude and trip time) nor pass/fail criteria, because national standards and/or grid codes should be taken into account for this purpose. This standard describes a guideline for testing the performance of automatic islanding prevention measures installed in or with single- or multi-phase utility interactive PV inverters connected to the utility grid. The test procedure and criteria described are minimum requirements that will allow repeatability. Additional requirements or more stringent criteria may be specified if demonstrable risk can be shown. Inverters and other devices meeting the requirements of this standard are considered non-islanding as defined in CLC/TS 61836. This standard may be applied to other types of utility-interconnected systems (for example, inverterbased microturbine and fuel cells, induction and synchronous machines). However, technical review may be necessary for other than inverter-based PV systems. The responsible committee is K 373 "Photovoltaische Solarenergie-Systeme" ("Solar photovoltaic energy systems") of the DKE (German Commission for Electrical, Electronic and Information Technologies) of DIN and VDE.
