hi I got a 1950 Siemens AC syncronous generator, 700 kW, and I´m going to retrofit excitation... the idea is to connect a DSR 100 Basler regulator, to feed the excitation on the main rotor... and use a GE multiline for protections.
But I´ll like to ask you some questions about this generator, or other old generators...
1.- Excitation time? or how to calculate it?
2.- Maximum capacitive reactive current? I mean how far I can go into power factor capacitive seeing it from machine side?
3.- Reverse power when the prime mover is a turbine (francis) ??
4.- Over load? how much time?
5.- Negative sequence? how much time?
6.- Zero sequence?? how much time?
I´m just asking for your usual numbers?? or if you got experience with older machines like this one...
thank and hope you´ll find interesting this threat
