Do PV sources provide fault currents to a shortcircuit in the system?
Do PV sources provide fault currents to a shortcircuit in the system?
(OP)
I have very large PV (solar) generation connected to the utility substation through an 500kW inverter and a 300V/34kV transformer. Now, for setting up the relays for coordination, I need to have fault current values. My question is: Will PV generation provide fault current through inverters, say, for a fault inside switchgear that ties the utility to this generation?
Appreciate your response.

RE: Do PV sources provide fault currents to a shortcircuit in the system?
If you have an inverter between PV panels and grid, I wouldn't worry about any more current than rated current simply because no more current is available from the panels.
If you have another arrangement, like a DC motor plus a synchronous generator feeding the grid, you will have high transient currents from the generator but not much short circuit current from the MG set simply because the PV cells, again, cannot deliver much more than they are rated for.
