Diesel-Generator Powerhouse Configuration
Diesel-Generator Powerhouse Configuration
(OP)
An islanded power system comprising of 4 off 1400 kVA, 480V, 60Hz diesel-generators is to supply a mine via a radial 34.5kV overhead line.
What is the preferred configuration of the generators, transformers, grounding and control ?
The 34.5kV system will be grounded at the Wye side of the generator transformer(s).
Are there any disadvantages in using Wye-Wye transformers with only the 34.5kV side grounded ?
Interlocks will ensure the generators can not run in parallel with the Utility.

RE: Diesel-Generator Powerhouse Configuration
GSU transformers delta connected on the generator side.
Grounded wye 34.5 kV system.
Four wire 34.5 kV system with distributed protective grounds on the neutral.
