Photovoltaic invertor connection to MV grid
Photovoltaic invertor connection to MV grid
(OP)
Dear All.
We work now on some technical evaluation of Photovoltaic invertor connection to MV grid.
Power is about 1MW. Im "responsible" for the protection requerements.
Actually, from my point of view, its same as co-generation issue.
Im use standard protection 50/51/49/67N
And would like use additional function for decoupling/ island mode:
27/59/81U/81O and ROCOF( df/dt), maybe voltge jamp.
Im think also add 25 functionality.
Could you please attached links to standards or rules in your countries.
Thanks in advance.
Best Regards.

I will order IEEE 1547.
Marmite, as usually UK guidance is good and useful documents.
Best Regards.
Have a nice weekend.
