There are two generators in a power system. No-load frequencies of the generators are 51.5 Hz and 51 Hz, respectively, and both are having droop constant of 1 Hz/MW. Total load in the system is 2.5 MW. Assuming that the generators are operating under their respective droop characteristics, the frequency of the power system in Hz in the steady state is _____
The two powers are P1=51.5−f and P2=51−f MW. Summing to2.5 gives102.5−2f=2.5, so f=50 Hz. The corresponding powers are1.5 MW and1 MW.
