Samenvatting:
In the Netherlands and worldwide, the installation of grid-connectedPV-systems is rapidly gaining pace and volume. This makes the need for
regulations of the requirements of grid- connected PV inverters urgent. This
document lays down requirements and recommendations for the design
qualification and type approval of inverters for grid-connected operation of
photovoltaic power generators with a current up to and including 16 A per
phase for single or three phase power conditioners (max. 11 kVA) feeding into
the utility low-voltage mains. Inverters up to 5 kVA can be single-phase
connected, and only a minimum level of protection is required. Islanding
prevention is considered to be implemented with sufficient safety and at low
costs by using a window for grid voltage and frequency, as well as the
frequency shift method. The document addresses the design of grid connected
PV-inverters with regard to performance, electromagnetic compatibility (EMC),
safety, utility interface protection and reliability. lt describes the
applicable standards for the design as well as for the experimental
verification of a number of aspects related to the items mentioned above.
This document can be used by manufacturers in the design process, by testing
institutes for research and development and by certification bodies for type
approval. 31 refs.
