multiple sets.
When the synchronization process starts,
the controller will automatically switch
from the status page to the
synchronization window page. When
parallel connection occurs, the ramp
adjustment process will also be
displayed in the synchronization window
page.
Automatic load distribution:
After multiple sets are connected in
parallel, the set can run with load, and
the power distribution control unit
inside the DSE8610MKII control module
will act on the speed regulating system
and the voltage regulating system to
distribute the load according to the
proportion set by the program in
advance.
When the models of multiple sets
connected in parallel are consistent, the
average power distribution is default;
when the models of multiple sets
connected in parallel are inconsistent,
the average power distribution by
capacity proportion is default.
Automatic control of sets connected in
parallel
When multiple sets run in parallel and
the load changes, the number of running
generator sets can be increased and
decreased according to the total load.
The set starts and stops automatically
according to the load size, making the
set work in the most economical state.
After multiple sets are in normal parallel
operation, the parallel control system
DSE8610MKII detects the load size
change. If the load exceeds 80%
(adjustable) of the total capacity of the
existing sets connected in parallel, the
parallel control system DSE8610MKII
controls to start the next set, and
automatically synchronizes and closes
for parallel operation after startup. At
this time, the built-in load distributor
DSE8610MKII will be put into operation,
and automatically detect the load
condition of each set, and automatically
distribute the load to the set according
to the load condition to balance the load
of the set.
When multiple sets are in parallel
operation, the parallel control system
DSE8610MKII detects the load size
change. If the load is less than 50%
(adjustable) of the total capacity of (N-1)
sets connected in parallel, the built-in
load distributor of the parallel control
system DSE8610MKII will automatically
transfer all loads out of the Nth set, and
after this process is completed,
disconnection signal is given to the Nth
set. The Nth set is released from parallel
operation. After disconnection, the
unloaded set is cooled regularly and
then shuts down and enters the standby
state.
