What Is Emergency Diesel Generator
The emergency diesel generator is a self contained diesel engine driven electrical generator set, which is located in a separated room with access from deck. Usually the generator is the self-excited, brushless type and can be set for manual or automatic operation. Auto will be normally selected, with the manual setting being used for testing the generator or in case of auto start failure.
Why An Emergency Diesel Generator Is The Best Power Solution
An emergency diesel generator is a very popular choice when looking for an alternative source of power. Whether it's an interruption in service, hurricanes, natural disasters, or something else, home and business owners both agree that a standby generator is the best way to ensure that emergency power where it needs to go both efficiently and safely.
Standby diesel generators are stationary, unlike their portable counterparts, and are fairly straightforward to use. However, if this is the first time that you are looking at standby generators for sale, it can be difficult to know how to choose the best option.
Operation of an Emergency Diesel Generator
Operating Procedure
① When the mains power fails, the generator should be started promptly.
② Before starting, check that the oil, diesel, battery, and voltage levels are normal. Is the water level in the water tank sufficient?
③ Inspect the blades and drive belts to ensure they are normal, and check for oil leaks and any loose connections throughout the unit.
④ The starting time should not exceed 5 seconds. If two consecutive starts are unsuccessful, wait 2 minutes before attempting to start again. If it cannot be started after three attempts, identify the cause.
⑤ Once the generator is running normally, monitor the operation of each instrument. If any abnormal conditions are detected, stop the inspection immediately.
⑥ Keep the unit load at or below 80% of the customer's specified value during operation.
⑦ After the mains power resumes, switch back according to the startup procedure. The generator should run at no load for more than 5 minutes before stopping.
⑧ During operation, ensure the blower is turned on.
⑨ After the emergency generator starts, it should be monitored for 2 hours, and the voltage, current, oil pressure, and water temperature should be recorded.
⑩ To ensure the normal and safe operation of the generator set, the unit must be inspected by observing, listening, smelling, and touching.
Daily Inspection and Maintenance of Emergency Generators
① Check the fuel level in the fuel tank and the water level in the water tank. If either is insufficient, add the necessary fluids.
② Check the oil level and add more if needed.
③ Inspect the stability of all accessories, ensuring the anchors and mechanical connections are secure.
④ Check the machine for oil and water leaks.
⑤ Verify that the meters are functioning normally, ensure the battery water is sufficient, and check that the battery voltage is normal.
⑥ Clean the exterior of the machine and its accessories.
⑦ The generator should be kept in an automatic standby state, and the battery should remain in a charging state.
Upon failure of the main diesel generators, the emergency generator set will start automatically and connect to the emergency switchboard to maintain power supplies to essential services. It is also used to restore power to the ship from a dead ship condition, enabling power to be supplied to essential services without the need for external services such as starting air, fuel oil supply, and cooling water.
The engine is normally equipped with a self-contained cooling water system, which is circulated by an engine-driven pump and cooled in a radiator. Cooling air is forced through the radiator by an engine-driven fan. The cooling water is mixed with antifreeze to prevent freezing in cold conditions, and a thermostatic electrical heater is fitted in the cooling water system to keep the engine in a condition ready for immediate starting. The engine-driven cooling water pump supplies the lube oil cooler, and after leaving the engine, the cooling water flows to the thermostat and back to the radiator or engine circulation pump.
The engine running gear is force-lubricated by an engine-driven gear pump, which draws oil from the sump tank and discharges it through the cooler and a filter to the lube oil rail. The system is equipped with a pressure-regulating valve to prevent overpressure of the lube oil supply to the engine.
The generator is supplied with fuel from a dedicated tank located in the emergency generator compartment. The fuel level in the tank, as per SOLAS requirements, should be sufficient for 18 hours of continuous running at maximum nominal load for cargo ships, and 36 hours for passenger vessels.
The engine is typically started by means of an electric starter motor, with power supplied by batteries. The batteries are equipped with an isolation switch and are maintained in a fully charged condition by a battery charger, which operates continuously and is usually equipped with an alarm that activates if the charger fails. A backup hydraulic starter is also fitted, with hydraulic power being manually generated via a hand pump. An accumulator charged by the hand pump provides the pressure to drive the hydraulic motor, which connects with the flywheel. When in automatic operation, only the electric starter motor is utilized. The engine should be started at least once a week and run at full load monthly.
The emergency switchboard is normally supplied from the main 440V switchboard, and when AUTO mode is selected, the emergency generator starts automatically by detecting no voltage on the emergency switchboard busbar. Usually, three start attempts are available under automatic control, with a start failure alarm activated if the generator fails to start.
The emergency generator air circuit breaker (ACB) will connect automatically to the emergency switchboard after confirming the continuation of no voltage, and the bus tie breaker on the emergency switchboard, which feeds from the 440V main switchboard, will open automatically when no voltage is detected.
To enable the emergency generator to start automatically in the event of a blackout:
1.The mode selector switch at the local control panel must be set to the AUTO position.
2.The fuel tank must always contain sufficient fuel for at least 18 hours of operation at full load.
3.The battery system must always remain on charge, and the batteries must be checked to ensure they are fully charged. If one of the battery systems fails, it must be disconnected and replaced as soon as possible.
Usually, after power has been restored on the main switchboard, the generator ACB and tie breaker will operate automatically, and the engine will stop. If the automatic system fails, the manual procedure to stop the engine after power restoration is as follows:
1.Turn the emergency generator operating mode switch to the MANUAL position.
2.Manually open the emergency generator circuit breaker.
3.Manually close the normal supply circuit breaker (tie breaker) to the emergency switchboard.
4.Manually stop the emergency generator by pressing the STOP pushbutton on the engine panel.
5.After the engine stops, turn the emergency generator operating mode switch to the AUTO position.
If, for some reason, the emergency generator fails to start automatically, it must be started manually, either using the battery starter or hydraulic starter mentioned above. The procedure for manual starting of the emergency generator and manual closing of the circuit breaker is as follows:
1.Check that there are no water, fuel, or lubricating oil leaks and that the emergency generator is available for starting, ensuring there are no restrictions on engine starting.
2.Ensure that the engine control panel is supplied with electrical power.
3.Ensure that the fuel system is fully primed and that all valves from the fuel tank to the engine are open.
4.Check the water level in the radiator expansion tank and add water if necessary.
5.The generator heater and switchboard heater must be switched on.
6.Ensure that the starter batteries are fully charged and able to supply electrical power to the starter motor.
7.Check the oil level in the engine sump and replenish if necessary.
8.Turn the engine control panel mode selector switch to the MAN position.
9.At the engine control panel, press the START pushbutton. The engine should turn over on the electric starter motor and should fire. When the engine fires, the START pushbutton must be released. The engine governor will regulate the speed to the preset value.
10.Check that the engine runs smoothly without excessive noise or vibration.
11.When the engine is running normally and the generator voltage and frequency are correct, the generator may be connected to the switchboard. The emergency generator circuit breaker can be closed by pressing the CLOSE/MAN pushbutton on the same panel.
The Components of a Emergency Diesel Generator
DIESEL ENGINE
A diesel engine is similar to the one you'd find in a car, truck, or any other large vehicle. This is the main source of mechanical energy, and the size of the engine is important if you are looking to hire a diesel generator; the larger the engine, the more power you will be able to produce.
ALTERNATOR
This component is responsible for generating the power output. An alternator consists of many complex components, and one of these crucial components is the rotor.
The rotor is a shaft that rotates from mechanical energy driven by the diesel engine, with carefully placed fixed magnets that create a magnetic field. This is where we see the concept of electromagnetism.
The magnetic field constantly rotates around another critical part of the alternator: the stator. To simplify, if an electrical conductor remains stationary and a magnetic field moves around it, an electric current will be induced.
FUEL SYSTEM
The fuel system supplies the engine with fuel through a pipe that connects directly to it. This system kickstarts the entire operation, and its size will dictate how long your diesel generator can operate.
A smaller fuel system may be used for generators housed indoors or portable units, while larger fuel systems are typically found for extensive, permanently fixed applications.
The internal components of the fuel system consist of various pipes to deliver fuel to the engine effectively. This is similar to systems found in most vehicles, including a fuel filter, a ventilation pipe, and a valve for the fuel tank to prevent unwanted overpressure.
There's also an overflow connection to ensure that if your tank is overfilled, the excess fuel will be channeled away without spilling onto the floor, the engine surface, or the alternator.
THE VOLTAGE REGULATOR
The voltage regulator is possibly the most complex component of the diesel generator. It regulates the voltage output. There are many details regarding the voltage regulator that we cannot explain in one section, so we'll break it down for you.
Without this component, the voltage and amperage of the AC current would vary according to the speed of the diesel engine. In our modern world, we rely heavily on a steady power supply, which requires a mechanism to stabilize it. In simple terms, the voltage regulator ensures that our power supply remains steady and manageable.
COOLING & EXHAUST SYSTEM
These two components are essential and, unlike the voltage regulator, are easier to understand. The cooling system prevents your diesel generator from overheating by releasing coolant, which counteracts any excess heat generated by the engine. The coolant absorbs the heat through a heat exchanger and dissipates it outside the generator.
Similarly, the exhaust system directs any gases produced by the diesel engine through a piping system and expels them from the generator.
LUBRICATION SYSTEM
The lubrication system is connected to the diesel engine and is managed by an oil pump, which circulates oil to ensure that all parts operate smoothly and do not grind against each other. Without this system, your engine would likely break down.
BATTERY CHARGER
Every diesel engine requires a battery charger to help initiate operation. This small motor needs a charged battery to function properly. The battery keeps the system charged and operational.
CONTROL PANEL
You will operate your diesel generator from the control panel, which contains a wide range of controls that allow you to manage various functions and monitor system performance.
Typical controls and outputs include:
●Start/Shutdown
●Frequency Switch
●Engine Mode Switch
●Engine Fuel
●Engine Oil
●Engine Speed
●Coolant Temperature
●Battery Charge
There are also many other controls and outputs available.
MAIN ASSEMBLY FRAME
The main assembly frame is necessary to contain the generator components. It helps keep everything together for optimal operation. The frame can be an open or closed design, depending on your setting.
