Good afternoon,
Please if you can, help me with a information.
If I have an autotransformer of 250 MVA; 400/132/38.5 kV(tertiary), impedance voltage 10.2% , with tap changer located in neutral, +- 8 steps, +9%-10%, voltage regulation on 132kV side.
Please let me know if exist a possibility to put this autotransformer in parallel with other 2 similar autotransfomers, but which have different value of impedance voltage on the ends of domain of voltage regulation.
The rest of data are similar.
My autotransfomer have the impedance voltage on the ends of the domain of voltage regulation: for max ratio: 7.84% and for min ratio: 15.07%
The other two autotransfomers have the values of these voltage impedances: for max ratio: 9.9% and for min ratio 10.3%
Thank you very much for your information.
