wat is syncronization . wat parameter will take for
syncronization.
Answer Posted / joshy govind
sychronisation is important when parrallel operation of two
generators or when we connect a generator to grid.
The generator supply must only be connected to a live
grid,
1. Phase angle difference
2. Voltage differnece
3. frequency diffenrence (slip)
between the generator and grid voltage are within
permissible limits and the phase sequence of both generator
and grid rotating field should be identical.
