When the synchronous generator is connected in quasi synchronous parallel with the power grid, all other conditions are met except that the generator voltage is only less than 5% of the power grid voltage. At this time, if the generator is closed in parallel, the generator will ()
A.
Generate huge current, so that the generator cannot be paralleled
B.
Generate a small current, which is inductive current
C.
Generate a small current, which is a capacitive current
D.
Generate a small current, which is an active current
