I have been learning about generator grid synchronization. I thought
I was making progress until I heard that there are some instances when
it is not possible to synchronize a generator to the grid. I was
wondering under what conditions that it is possible or not possible to
synchronize a generator to the grid? Does it depend on the generator
- synchronous or induction? Does it depend on the load, power,
voltage difference between the generator and the grid?
Yes, it depends on all these things!!! The generator must be
with the grid. actually, the grid will impose the generator speed (3000 or
rpm) but in addition, the turbine that is driving the generator must provide
enough power such that the generator send current into the grid; if not, the
grid will try to send power to the generator (converting it into a motor)
will activate all kind of safety measures to disconnect the generator!!!
Thanks for the information. I was thinking along similar lines but I
heard that sometimes it depends on the generators/machines. There are
some generators or machines that cannot be synchronized. Is this
true? if yes, I was wondering what kind of machines or generators
cannot be synchronized?
