Alternator synchronization:now the last two paragraphs are contradictory. pls read and all rfs in droop speed control.thank you.Wdl1961 (talk) 23:27, 13 February 2010 (UTC)Reply

You're too terse, i don't understand. What seems to be the contradiction? --Wtshymanski (talk) 01:22, 14 February 2010 (UTC)Reply


At least one machine in a utility grid system must be run as an //"isochronous" governor;// it will maintain a constant speed and [[utility frequency|system frequency
In a large system with hundreds of generators connected, the connection of any one machine will have //negligible influence //on the rest of the machines.


this works with a small no of generators only ;called (small) island mode.Wdl1961 (talk) 02:48, 14 February 2010 (UTC)Reply
Please don't abbreviate so much, it's hard to follow when you don't write complete sentences. So, what keeps the grid at 60Hz? --Wtshymanski (talk) 03:33, 14 February 2010 (UTC)Reply
the grid runs hardly ever at exactly 60 or 50 cycles . the governors are readjusted to catch up or fall back .see time control in droop control.there is a protocol somewhere east coast 10 sec every 30 min max deviation without readjustment.see ref>http://www.nationalgrid.com/uk/Electricity/Data/Realtime/Frequency/Freq60.htm </ref>.Wdl1961 (talk) 04:07, 14 February 2010 (UTC) .Reply
atomic powerplants have no useful droop at all running baseload. some hydro is run at max efficiency.there are lots of relative unimportant details that do not add anything .Wdl1961 (talk) 03:06, 19 February 2010 (UTC)Reply
