Eli5: How do you synchronize a whole national grid?

541 viewsEngineeringOther

Back in 2015 Turkey has been synchronized to the European grid.
Now my question is, how do you synchronize a whole country to another country? Adjusting the voltage is pretty simple by using transformers, but what about the frequency and phase angle? While synchronizing a generator to the grid is just a matter of changing the rpm of the generator, but obviously you can’t do that, in order to change the frequency of the grid, because if your generator is to slow it will be powered by the grid. So how do you synchronize a whole country?

I can’t find any info because I don’t know the right search terms, but I’m aware of a type of synchronous generator that has electronically switchable stator windings. This allows the control system to effectively rotate the stator field, thus adjusting the relative rotational speed between the rotor and the stator. This means the output can be in phase over a wide range of rotor RPM which is useful in many renewable energy fields. Very cool tech, and I wish I had a link to post.
