How does a system control centre in a utility plant gets
the grid frequency of the electrical network (50 Hz or 60
Hz)by the SCADA system?

Answer Posted / jim

SCADA does not control frequency. The source generators produce at 60 cycle. The ultimate load on the grid will never be perfectly matched with the generation. This load mismatch will control the grid frequency by + or - from 60 cycle. Your wall clocks will change speed.

in cvt,there are two windings,1a,1n and 2a,2n.in my one project i use only one winding i.e.1a,1n. the other winding is not in use, so i connect it in open delta and want to close it by ibsertibg thermal resistor. the output of cvt is 132kv/115/sqrt3. plesae tell me exact value of resistor, so i may close it to avoid the resonance phenomenin. send me answer on this email adress please. aetcon-po@aetcon.com
