As a backup power
source, emergency diesel generator provides AC power to the load in case of
main power failure, ensuring continuous power supply of the load. It is widely
used in various industries such as communication, coal mine, etc., and various
faults occurred in the operation of the diesel generator set. Most of them are
caused by untimely, inoperative or improper operation of the operation manager.
Emergency
Diesel Generator Start-up Operation
Release the
"emergency stop" button on the control panel.
Turn the power switch
knob on the control panel to the “ON” position, the power indicator light is
red, and the generator's controller power is on and displays normally.
Press the manual button
on the generator controller panel, the indicator on the manual button lights
up, and a palm is displayed in the lower right corner of the LCD screen. This
is the manual start mode.
Press the start button
on the generator controller panel to start the generator, the generator start
indicator lights up, and the LCD screen shows that the three-phase voltage
rises from 0V to 230V.
Check the generator for
abnormal noise or vibration, whether there is oil leakage, water leakage or air
leakage, and whether the control panel displays abnormality.
After confirming that
the generator power output has stabilized at about 230V, close the generator
control cabinet output circuit breaker, and the diesel generator starts normal
power supply.
Emergency
Power Output Operation
Check the emergency
power supply incoming cabinet breaker, the voltage output shows about 230V, and
check that the output status of each feeder circuit is normal.
Operation
of Emergency Power Distribution Cabinet in Each Substation
Check and confirm that
the incoming power supply of the emergency power distribution cabinet of each
substation has been cut to the generator power supply state (backup power
supply).
If ATS is not switched
to the standby power state, the ATS control switch is cut to the manual state,
and the special handle is used to manually switch to the standby power supply
state (generator power supply).
Check the normal power
supply status of each feeder circuit of the emergency power distribution
cabinet.
After the diesel
generator is working normally, it is necessary to check the running state of
the generator and the output current, voltage and other parameters.
Emergency
Diesel Generator Shutdown Operation
Confirm that the
incoming power supply of the emergency power distribution cabinet of each
substation has been cut to the mains power supply (common power supply).
Confirm that the load
has completely exited and disconnect the generator emergency power inlet
cabinet circuit breaker.
Disconnect the generator
control cabinet output main circuit breaker.
Make sure that the
generator is cooled for about 3 minutes at idle speed, then press the stop
button on the generator controller panel, the stop button indicator lights up,
and the generator stops normally.
If there is an emergency
to stop the generator, you can not turn off the generator control cabinet
output circuit breaker, directly press the red "emergency stop"
button on the controller panel, and the generator will stop in an emergency.
After confirming that
the generator is stopped, turn the power switch knob on the control panel to
the “off” position, the power indicator light is off, and press the “emergency
stop” button to complete the shutdown of the diesel generator.
Notes:
When the diesel generator is running at no load, it shall not exceed 5 minutes.
Do not take off the
battery during the operation of the diesel generator to avoid the damage of
electronic components.
Do not open the lid of
the water tank before the diesel generator set is cooled to prevent scalds.
