Abstract

The short circuit behavior of solar farms are different from conventional generating stations. These generating resources are
static in nature and have a rich power electronic interface with a grid, limiting these solar farms’ short circuit capabilities.
The solar inverter voltage versus short circuit current characteristics is modeled to supply the fault current within inverter
designed ratings. In this research paper, a large number of solar power investors are grouped to pool their power into the
grid. Short circuit studies are carried out for a 500 MW solar farm with string inverters rating of 3125 kW per IEC 60909.
The protective relaying coordination is performed as per IEEE C37.90 and IEC 60255-1 relaying standard.
