Islanding fault
Witryna16 lip 2015 · Islanding is a critical and unsafe condition in which a distributed generator, such as a solar system, continues to supply power to the grid while the electric utility … Witrynaislanding condition, the injected current from the inverter towards the unpowered grid affects the voltage in the PCC. Therefore, the active power generated by the DPGS in an islanding fault can be expressed as follows: PDPGS = Vo 2 /R G (1) where Vo is the voltage at the PCC and RG is the equivalent resistance after the PCC (grid side).
