currently i have several generators that has identical parameter. cause of increasing demand, i will add new generatos with different parameter (capacity, speed and etc) to my power plant. my question is :
I need some advice for designing power plant
1. how we connect the new generator? in the same terminal now or i have to buy new one?my current terminal has enough short circuit capacity.
2. currently i have no grounding in my generators but i have grounding in my trafo (at the same side with generator). from my last study, i have to change my configuration. to limit sc current in generators, i have to install new ngr. how much ngr i must buy?is each of generators must have 1 ngr or just 1 common ngr for all my generators?what is the effect for my protection for both configuration?
