In this section you will learn the benefits of
using a power management system they're
closed today may have a number of
generator sets split best bars and a
variable load automatic control of all
these have become common practice to
ensure continuity of service and an
efficient management of both generating
and load equipment typical power
management system will incorporate the
following functions automatic line
frequency adjustment load monitoring
load dependent start/stop of generator
sets supervision of heavy consumers
switch on load sharing automatic start
and connect after blackout other
functions which may be controlled by the
power management system include control
of pre lubrication pumps on the standby
Diesel's automatic load dependent change
of fuel on larger auxiliary Diesel's
diesel 2hf oh and vice versa click on
item to have that item described to you
in greater detail the power management
system sends increase/decrease signals
to the governor without the power
management system fine adjustment for
the frequency has to be executed
manually by means or the apt down
switches on the main switchboard the
total system load is monitored and
compared to the available online
generating capacity the system's will
advise the operator to start off stop
the generator sets in auto mode this
will be carried out automatically the
total system load is monitored and
compared with the available online
generating capacity
the system would advise the operator to
start stop the generator sets in
response to varying load in auto mode
this will be carried out automatically
the power management system will
consider the total load in relation to
the available online capacity before
allowing the heavy consumer to start
this is them to prevent blackout if the
actual old and a heavy consumer load
totaled is greater than the available
online capacity the power management
system would start and connect the next
generator before the heavy consumer is
allowed to be switched on the blackout
logic is triggered when the power
management system reads zero volts from
the main burst bars the highest priority
generator would attempt to start and
connect to the main bus bars if this
fails the next diesel generator will try
to start and connect move the cursor
over the different push buttons and
indicators for a description
let us assume that one generator is
connected and the other one is ready
both generators are in auto and are set
to equal load sharing you can now
increase and decrease the load on the
generators and change from equal load to
optimal load when finished press the
continue button by now it should be
obvious but to achieve maximum safety
during maneuvering both generators
should be connected and equal load
sharing selected as a control mode note
that even if the Prince of the same
there are several types of power
management systems found on the market
so you must always familiarize yourself
with the actual system found on board
your ship
