How to Effectively Synchronize Multiple Generators in a Hospital Setting?

[dhanking23]

i am BSEE student, my project study is to synchronize the generator of an hospital, it have a one 313KVA standby-power diesel gen.,and three 100kva transformer.The generator system is operated manually and no ATS or UPS. one more new building is being build so the transformer will be upgrade to a higher vale.
1)how i can connect the new gen. to the old gen. and to the synchronize panel?
2)what is the new gen. to be buy?(rating, etc.)

These is my title: To synchronize the generator system of the ____ Hospital.
Anyone have a good title?
Thanks.

Hello,
its a good and challenging project, first of all the synchronization of 2 generators consist of 4 parts:
1- the voltages should be equal in all phases in the 2 generators
2- the 2 generators should be in phase
3- the output of the 2 generators should have same frequency
4- the sequence of different generator phases in the two generators should be the same (meaning if the sequence of phases in generator 1 is :a-b-c, then the sequence of phases in generator 2 should also be:a,b,c)
So you have to make a circuit that do the 4 steps of synchronization.
with respect to the rating of the generator, it depends on the load you have in the building.
