Section 13 Generator Management Information
13.1 Generator Management
Purpose
Generator Management is intended to decrease fuel
consumption, environmental emissions, and sound
emissions while improving generator life and
serviceability.
13.2 Generator Management Basic
Function
Generator Management supplies a stop signal to a
generator. If Generator Management fails or is turned
off, the stop signal is removed, resulting in the generator
starting. Most faults relating to Generator Management
will cause it to be disabled, causing the generator to
start.
Generator Management is disabled when the start
signal to the system is removed, and must go through a
stability delay before it will stop generators.
13.2.1 Sequence of Operation
This sequence follows the operation of a normal
paralleling system which uses Generator Management.
When a start signal is applied to any of the generators in
the paralleling system, all the generators that are in auto
andhavenoshutdownfaultswillstart.
Figure 13-1 illustrates the system after the first
generator has reached rated voltage and frequency and
has closed to the paralleling bus (any of the generators
can be the first to close, d epending on which generator
reaches rated voltage and frequency first). The Total
System Capacity is that of a single generator and the
load is low enough to be supported by a single generator
because non-critical loads have been shed by a Load
Management (also called Load Add/Shed or Load
Control) system (not shown).
