Question
Electrical Machines Question on DC Generator Efficiency
The incremental cost characteristics of two generators delivering a total load of 200MW are as follows.
df1/dp1=2.0+0.01P1.df2/dp2=1.6+0.02P2
What should be the values of P₁ and P₂ for economical operations?
A
P1−P2=100W
B
P1=80MW,P2=120MW
C
P1=200MW.P2=0MW
D
P1=120MW,P2=80MV
