if generator is running in iso mode parrallel with grid and
suddenly grid breaker off what will happen?
Answer Posted / blake australia
If generator is running in ISOC mode (opposed to base
loading) and the grid connection is lost the generator will
try to pick up the load on the connected network. If the
load is too big then the generator will trip. If the load
isn't the generator will continue to run as before. ISOC
mode means that the generator is running in its own
frequency control, so if it looses the grid frequency it
can still run based on its own frequency.
If the generator was running in base load and the breaker
trips the generator will have no frequency reference.
Usually they are configured to change themselves back into
isoc when grid reference is lost but you should check if
unsure.
