Generating Set Control
Protection System
During
the load operation of diesel generator, it is necessary to monitor and control
the working condition of the unit at any time, report all kinds of faults
accurately and timely, and automatically protect the genset can supply power
safely and reliably.
The
electrical control and protection system of generator is generally composed of
integrated controller, sensor, instrument and so on. The function of the sensor
is to monitor the temperature, pressure and other signals on the diesel engine
and convert these signals into current signals.
At
present we use more is Deep Sea DC control system. Model includes 520, 550,
560, 5110, 5220, 5510, 7310, 7320 and other controllers. DSE7320 controller is
widely used in our power generators no matter it is Cummins generator, Perkins
generator, Volvo generator or Chinese brand generator. If it is parallel diesel
generator set, we often use DSE8610 or DSE8620 control module.
The
DSE7310 is an Auto Start Control Module and the DSE7320 is an Auto Mains
(Utility) Failure Control Module suitable for a wide variety of single, diesel
or gas, gen-set applications.
Monitoring
an extensive number of engine parameters, the modules will display warnings,
shutdown and engine status information on the back-lit LCD screen, illuminated
LEDs, remote PC and via SMS text alerts (with external modem).
The
DSE7320 will also monitor the mains (utility) supply. The modules include USB,
RS232 and RS485 ports as well as dedicated DSENet® terminals for system
expansion.
DSE7320 control module
Both
modules are compatible with electronic (CAN) and non-electronic (magnetic pick-up/alternator
sensing) engines and offer an extensive number of flexible inputs, outputs and
extensive engine protections so the system can be easily adapted to meet the
most demanding industry requirements.
DSE560
module is an automatic generator control module that automatically starts and
stops the engine and indicates operating and fault conditions. When the
generator is automatically stopped, the LED on the control panel flashes and
displays the cause of the failure through the LCD icon.
The
operation is realized through the three control positions of the knob switch on
the control surface: automatic, manual, and stop. The Triangle button is used
to see the operating parameters of the unit.
Charger:
Nowadays, generator is mostly as back up power. Sometimes the generating sets
won’t be turned on for one or two months. And the battery has self-discharge
phenomenon, so that the unit cannot be used in emergency because the battery is
out of power. Therefore, it is necessary to install the charger. Usually, use
the mains/electric supply to charge the battery. When the battery voltage
reaches the specified value, it will be disconnected.
