Answer / l.sivagurunathan

in case of nuclear power plant due to grid disturbance like
under frequency condition, generator will feed power to one
or few parts of grid only which are predefined and remaining
part will be isolated from grid. this mode is islanding mode
whereas in houseloading mode generator will feed to its own
houseload only if grid is not further stabilised, that is
also for few minutes only till grid gets normaliesd and
restored. otherwise generator has to be manually
tripped.these arrangements are for baseload operating
generators only. because of these arrangements grid can be
restored easily

Answer / wasim

houseload is plant's load only, whereas in islanding certain load beside plant's load is defined to feed. houseload operation usually acceptable for 1 hour

DCS marshaling Cabinet Power supply can be replace during plant running time? Answer Yes it is possible. I am talking about the controller and cards power supply modules. They are always redundant and connected through diode so that if one power supply fails the other can take the charge immediately.so it is possible to replace one of them in running plant if the other one is healthy. MY question is how switching done.
