Hi everyone,

I have this project and I really need some help to understand it and ways to start it...

Thank you in advance.

The pdf file is attached.

 

The instructions seem perfectly clear. Design a substation that runs off 115KV.
Meanwhile, I'll tell the bosses here that this belongs in the homework section.

 

If you don't understand it enough to ask specific questions, then I suggest you approach your instructor and work with them on getting your understanding of the course material up to a point where you can at least start asking specific questions.

 

I have a question, How many transformers do I need to build the cheapest substation?

 

I have a question, How many transformers do I need to build the cheapest substation?

Make yourself a sketch of the loads and proposed layout. It will help you come to a solution. You might have options on the number of transformers, but until you lay it out and make some initial calculations, you can't answer the question.

 

Excuse me,

Can I use only one transformer to supply more than one motor.
As in this question, 4 DC motors, 3 induction motors and 2 synchronous motors.
For example, one transformer for the 4 DC motor.
And one for the 3 induction motors. Lastly, one for the synchronous motors.
Thank you
