retrofit on hydro genset
retrofit on hydro genset
(OP)
I got an old hydro unit, 2000 kw, with a pilot inductor (dc generator) with the output connected to brush and the main generator rotor... and now, I want to retrofit it, and mount a new AVR, maybe a DECS 200, and with this AVR control the field of the pilot inductor, but the customer ask me for load rejection, he want to have a load rejection and keep the unit working.... and I see the time constants, on unit are great... cause, I got the sum of the dc generator time constant and main generator time constant for deexcitation, and maybe i could have a problem when i loose the load...and maybe i got a overvoltage, cause we change avr to work from PF control to volts control
What could be a good solution?
