Eli5: How do you synchronize a whole national grid?

549 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?

that is how you do it. you very slowly change the rpm of all generators on the grid until they match the grid you want to connect with.
