241Section 13 Generator Management InformationTP-6953 7/19
By the time the Generator Management Stability Delay
has expired (see Figure 13-4), the load has settled
down to a steady-state level. Generator Management
can start timing to stop Generator 4 because the system
load is below the stop kW of Generator 4.
Figure 13 -4 The Stability Timer has Expired
When its Stop Delay is complete, Generator 4 will
soft-unload (gently transfer load to the other generators)
and disconnect from the paralleling bus, either stopping
or going into engine cooldown after disconnecting. After
Generator 4 has stopped, the system continues to feed
the load with generators 1, 2 and 3 as illustrated in
Figure 13-5. The load has decreased further from the
peak loading which occurred right after startup.
