Relay Protection for Distributed Photovoltaic Grid Power Transformers

7.1  Distributed Photovoltaic Grid Transformer (DPV-GT) Protection

The addition of the DPV energy resource to the distribution or subdistribution level impacts the relay system beyond the point of common coupling (PCC). Generally protection systems are designed for the traditional radial circuit formation. Additional concern is attributed to the bidirectional power flows, increased fault levels, safety, voltage swells, fluctuations and transients, equipment ratings, and autoreclosing. These affect the relay protection schemes applied to the configuration. A distributed resource like DPV when added to the system necessitates the insurance of safe and reliable operation ...
