Alternator synchronization:now the last two paragraphs are contradictory[edit]
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)
- You're too terse, i don't understand. What seems to be the contradiction? --Wtshymanski (talk) 01:22, 14 February 2010 (UTC)
- 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)
- 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)

- 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) .
