Protection
(OP)
Hi Guys,
I have been given a protection single line diagram for a
induction generator which will be connected to local utility.
The actual situation is that there are two induction generators but the diagram has only one, so I have to develop a new one with two, So my question is
Q #1 Should I just copy and paste same protection with the second paralled generator . If a fault occurs in one, is there any coordination required that the other will be stopped alos.
I dont wanna just give wrong information with my less knowledge of protection.
thanks

RE: Protection
Both generators are similar I think they had an impression that it is gonna be one generator, so they did not put the second one, from the diagram I see they have only two relays
SEL 551 and 547, I looked at the websites and I am also wondering, when we talk about bus protection that is a part of switch gear protection, in my case will these two relays take care of bus protection or we have to have a seperate bus protection.
Thanks
