1.what to do if ferquency of any power system continue to
decrease ?
Answer Posted / sanju
u can bring the frequency to normal by decreasing the laod
shared by the generators. But i dont think any power system
engineer can afford to loose laod. The frequency can be
brought back to the noraml valsue after the following:-
1.make sure that the governor sets of all generators are
working fine.
2.make sure that that the droop characterstics of all the
governors connected are same.
3.make sure that there is no problem with prime mover side.
i hope this wl solve ur problem

If any HVDC line is going with positive & negative(the negative usually have return path of current with earthing electrode). Now the question is if this HVDC earthed electrode which is using as return path and earthed any nearby 400kv or 220kv AC substation equipments. which will be the impact of this on AC substation & its equipment, how severe may be this and what should be the minimum distance require between HVDC earthed electrode and AC substation equipments? It's really an high engineering level question...Dare to answer and increase your knowledge.
