List of top Electrical Machines Questions on DC Generator Efficiency asked in CUET (PG)

Calculate the area required for Rotor to generate 4.5KW in a 5m/s. Assume a drive train efficiency of 0.85, a generator efficiency of 0.75, and an altitude of 92m

The incremental cost characteristics of two generators delivering a total load of 200MW are as follows.
\(df_1/dp_1=2.0+0.01 P_1.\; df_2/dp_2=1.6+0.02 P_2\)
What should be the values of P₁ and P₂ for economical operations?
