Operation Manual of WEICHAI GENSET
current, busbar voltage and generation
circuit breaker closing are fed back.
■ Required settings:
Input: remote on-load start.
Output: set closing output.
Multiple sets: priority and ID
number cannot be repeated
Load requirements: Initially start all
the sets or start sets according to load
requirements.
Manual startup and shutdown steps:
Place the switch knob on the switchgear
in the automatic position, operate the
DSE861MKII controller of the control
panel beside the set, press the manual
button to put the set in the manual
mode, then press the start button to
start the generator set, and after the
generator set rises to the rated state
after idle running for some time, check
whether the set voltage and frequency
are correct, oil pressure and water
temperature on the control panel are
normal and the set is abnormal. If the set
is in normal condition, press the closing
button on the DSE861MKII controller: if
there are no sets connected in parallel
on the busbar at this time, the set
directly issues the closing command to
control the closing of the circuit breaker;
if there are sets connected in parallel on
the busbar at this time (other sets have
been closed), the DSE861MKII module
will automatically issue a
synchronization command to control the
set to carry out speed adjustment and
voltage adjustment. When the
alternator voltage and busbar voltage
frequencies are detected to be the same,
the voltage is the same, and the phase
angle is consistent, the DSE8610MKII
module will automatically issue a closing
command to control the circuit breaker
to close. At this time, the set will
complete the synchronization process
and realize parallel operation. After
parallel operation,
in manual mode, it is necessary to
confirm before shutdown that the power
generation of the remaining sets
connected in parallel can meet the load
requirements after shutdown of the set.
Press the opening button on the
DSE861MKII controller directly and wait
for the load transfer to be completed.
After the opening is completed, press
the stop button on the DSE861MKII
controller to ensure that the diesel
engine will stop after the cooling delay.
Note: Manual operation of the circuit
breaker at the switchgear is prohibited
when multiple generator sets are
manually connected in parallel.
Automatic startup steps:
Place the switch knob on the switchgear
in the automatic position.
Place the DSE861MKII controller of the
control panel beside the set in auto
mode. After the DSE861MKII controller
of the control panel beside the set
receives the remote start signal, multiple
diesel alternators start at the same time,
and then any set first automatically
closes after the rated voltage is met (the
priority of multiple sets is the same level)
to transmit power to the busbar section,
and then the DSE8610MKII parallel
modules of other sets perform
simultaneous detection. After it is
detected that the frequency, voltage and
phase angle of the alternator and busbar
are the same, the alternate
automatically closes to the busbar
section to realize parallel connection of
