Question
two generators supplying a load.
Generator I has a no-load frequency
of 62.5 Hz and a slope Sp1 of I
MW/Hz. Generator 2 has a no-load
frequency of 62.0 Hz and a slope sp2
of I MW/Hz. The two generators are
supplying a real load totaling 2.5
MW at 0.8 PF lagging.
(a) At what frequency is this
system operating, and how
much power is supplied by
each of the two generators?
(b) Suppose an additional I-MW
load were attached to this
power system. What would
the new system frequency be,
and how much power would
Gl and G2 supply now?
