I'm sure that your generators do not generate at 220 kV. In reality you will have GSU (Generator Step-Up) transformers that connect the generators to the transmission system. The actual generators might actually be rated at something in the range of 4 kV to 36 kV.
Unless you've already got a 220 kV grid, you want to change the GSU transformers to ones with a high voltage side of 380 kV.
Assuming the generators have a rated voltage of 20 kV, you would omit the 20 kV to 220 kV GSU transformers and instead order 20 kV to 380 kV GSU units.

Are you trying to step up? You will need to supply 3phase to the grid.
I am assuming that you are trying to step down. In which case again assuming 3phase from the 380 kv line then you would need a 3phase Y connected input on the powersupply. The step down factor of 1/&radic 3 means that you will have 220kv between phases.

Use a step-up transformer to match your supply voltage to the grid voltage.

You could step the supply voltage up to 380kV

you need to get a power transformer to step up the voltage - - - have a look at some builder's merchants or technology companies...

I believe that would be called a step down transformer.
