machine droop setting is 4%. let's say machine is at 20 MW & rated load is 40 MW. Hence it is at 102% TNR. (TNR-TNH=2%) If TNH reduces by 1% machine's load will increase by 25% of rated load (25% of 40MW) 10MW. machine will increase to 30 MW from 20MW.
1) Will machine stay there or it will again come down to 20MW to maintain original TNR-TNH=2% at reduced TNH of 1%?
2) If three machines of 40MW are operating at different droop settings say 4, 5 & 6%, how thaey will share increased load of 10 MW? Is there any equation or graph for this situation?
