Hello,
We have typically been designing large scale PV plants with Y-D-Y GSU's with a NGR on X0. Why not use a Y-D transformer and use novel methods of detecting ground faults (3V0)? I understand that you would need to do a more in depth insulation study because of the larger neutral shift and...
We have two identical synchronous generators connected at low side 13.8 sharing 3 GSU- 2 identical 138kV GSU's and 1 69kV GSU. Each generator has its own Basler decs 300 AVR and utilizes reactive droop compensation of 5%. Following a disturbance, the generators will cause MVAR oscillations one...
