Generator Principles

The following is a brief discussion of generator operation and its relationship to the mechanical load placed on the diesel engine.

Electromagnetic Induction

Electromagnetic induction, the basic principle of generator operation, involves the movement of an electrical conductor through a magnetic field. Figure 9-1 shows the principles being discussed in this section. As the conductor passes through the magnetic field, in this case downward, it cuts each of the lines of magnetic force (flux) which causes a current to be “induced” in the conductor. Because the conductor has a resistance, it is known from ‘ohms law’ that the voltage is equal to the current times the resistance.

Therefore, a voltage is also ‘induced’ between the two ends of the conductor. If the conductor is connected to a closed electrical circuit, this voltage would cause a current to flow. The amount of current flow is a function of the voltage induced and the electrical resistance of the load in the circuit.

The Voltage of the Best Silent Diesel Generator

The actual voltage induced in the conductor is determined by the number of lines of flux cut per unit of time. Two key factors affect the magnitude of the voltage induced.

• The speed at which the conductor moves through the fixed magnetic field and the strength of the magnetic field determines the output voltage. This speed is a function of the rotational speed (RPM) of the generator/engine. As the speed of the engine and the generator increases, the voltage produced also increases. Since the operating speed of the engine and generator is constant in order to maintain the desired frequency, another method of voltage control must be employed.
• The generator output voltage is most often controlled by regulating the strength (flux intensity) of the magnetic field. This is accomplished by the generator excitation system. The excitation system monitors the generator output and regulates the magnetic field to maintain the desired voltage. As the load on the generator is increased, an increase in current flow causes the voltage to drop. The excitation system senses this decrease in voltage and increases the strength of the magnetic field to return the voltage to the desired level.

Figure 9-2 shows the principles discussed above implemented into a machine to produce a voltage. In this implementation, a ‘U’ shaped form is provided with a ‘gap’ between the open ends of the ‘U’. A coil of wire is wrapped about the legs of this form to produce a magnetic field across the gap. In the gap, an armature is formed by a loop of wire. The loop exits the armature onto two slip rings.

The slip rings are contacted by brushes that connect the generator to the outside electric circuit. An engine or some other prime mover is connected to the armature causing it to rotate inside the gap. When the ‘field’ coil is energized to establish a magnetic field/flux in the gap and the armature is then rotated, a voltage is generated in the armature. The slip rings and brushes conduct this voltage out to some load “A.”

Figure 9-3 shows a blowup of the armature in the gap. As the armature is rotated in its initial position, no voltage is created because the magnetic flux is equal but opposite on both branches of the loop. This is shown in the part of the diagram labeled ‘Start.’

As the armature is turned to a position 90 degrees from the first, the two ends of the loop is acted upon in a manner wherein the voltages generated at each end of the loop are additive, as shown in the ‘1/4-cycle’ diagram. Peak output voltage is generated at each cycle point. As the armature continues to rotate, it again gets to a position of no voltage generation, shown in the ‘½-cycle diagram’.

As the rotation continues, a voltage is again generated. A close examination of the wiring out of the armature reveals that the connections have become inverted. This results in the opposite polarity of the voltage. The diagram at the bottom of the figure shows the resulting build-up and decay and opposite polarity build-up and decay again through two cycles (two rotations of the armature).

The resulting voltage build-up and decay form a sinusoidal wave that is defined as an ‘Alternating Current’ or AC. This is the basis for a single-phase alternator. Two other sets of coils offset by 120 degrees and connected to slip rings would form a machine to generate 3-phase AC power.

This is the basis for all AC 3- phase generation. If instead of using two slip rings a single ring that is split into two segments were used, as the armature rotated, there would be a buildup and decay of voltage as before, but the split slip ring would reverse the connection on each half revolution. The split slip ring configuration is commonly referred to as a ‘commutator.’

This would result in a machine that puts out a pulsating DC current. By combining a great many poles and the same number of segments on the armature commutator, an almost steady DC output would be produced. This is the principle of the DC generator or motor. The AC alternator described above has a number of problems.

The armature and its slip rings have to handle all the load current that is produced by this generator. The brushes and slip rings restrict the amount of current that can be handled. To eliminate this problem, the design and construction were changed such that the small excitation current now goes through the brushes and slip rings to the rotating armature field. The large AC current induced into the stationary stator windings is transmitted to the loads by solid connections.

This same principle also applies to AC synchronous motors as there is little difference between an AC generator and an AC synchronous motor. It is a matter of what is driving the system – an electric motor or an engine-driven generator.

This also simplifies the construction of the generator. These machines very often also are called ‘alternators’ in as much as the voltage and current are alternating. A three-phase generator/alternator is simply three single-phase machines interlaced with one another, sharing the same rotor assembly, with wiring brought out to connect each phase to the electrical
system.

The result of the interlacing of the alternator windings is shown on the voltage trace shown at the bottom of Figure 9-4. The upper part of Figure 9-4 shows how the current of each/any phase acts to produce the power. The left-most diagram shows the current in phase with the voltage. This is the case when the power factor is 1.0 (unity). The real power (KW) in that case is equal to the apparent power (KVA). These terms will be discussed later. When the current is not in phase with the voltage, there is a lesser power factor, and the KW is less than the KVA. The KW is still in phase with the voltage, but the KVA has shifted slightly due to the shift in the current. This introduced KVAR and will be explained later

The place where the generator set will be installed must be, clean, dry, well illuminated and ventilated, free of corrosive or conductive pollutant substances like dust, lint, smoke, oil vapor, exhaust smoke, etc…

Be sure to leave enough blank space around the generator set, in order to ease future maintenance or repair activities Remember that it can be necessary to disassemble the main parts like the engine, alternator, or base frame in some cases. The base ground where the generator will be settled must be clean dry and must have a good drainage system. Put the generator set in such a place that nobody unauthorized can access it, or at least take necessary precautions about it.

Place generator sets in such places that they will not be affected by the operation of any other machines. Do not install or run the generator set at any place that has any possibility of risk in terms of safety of operation.
Also, provide the necessary precautions (canopy option) or protections against bad weather conditions if it will be placed outside.

The doors of the room that the generator set will be placed in, must be at enough size for the main parts (engine, alternator, radiator, etc…) to pass through. Also, ventilation windows can be built portable or mobile for
this purpose.

Diesel Generator

A diesel generator is a device that converts diesel fuel into electricity. Diesel generators are typically used as backup power sources in the event of a power outage, but they can also be used as primary power sources in remote areas where there is no grid electricity available.

Diesel generators work by using a diesel engine to turn a generator. The diesel engine burns diesel fuel to create mechanical energy, which is then converted into electrical energy by the generator.

Diesel generators are available in a variety of sizes and power outputs. Some diesel generators are small enough to be portable, while others are large enough to power entire buildings or communities.

Diesel generators are a reliable and efficient way to generate electricity. They are also relatively easy to operate and maintain.

Here are some examples of where diesel generators are used:

• Hospitals and other critical facilities: Diesel generators are used to provide backup power in hospitals, data centers, and other critical facilities. This ensures that these facilities continue to operate even in the event of a power outage.
• Construction sites: Diesel generators are used to provide power for construction tools and equipment at construction sites. This allows construction work to continue even in remote areas where there is no grid electricity available.
• Emergency services: Diesel generators are used to provide power for emergency services, such as ambulances and fire trucks. This ensures that these services can continue to operate even in the event of a power outage.
• Remote areas: Diesel generators are used to provide primary power in remote areas where there is no grid electricity available. This allows people living in these areas to have access to electricity for lighting, cooking, and other essential needs.

Diesel generators are a valuable tool for generating electricity in a variety of situations. They are reliable, efficient, and easy to operate and maintain.

Diesel Generator Outputs

The output of a diesel generator is measured in kilowatts (kW). The output of a diesel generator is limited by the size and power of the diesel engine that it uses. Diesel generators are available in a variety of sizes and power outputs, ranging from small portable generators that produce a few kW of power to large industrial generators that produce thousands of kW of power.

The output of a diesel generator is also affected by a number of other factors, including:

• Fuel quality: The quality of the diesel fuel used in a generator can affect its output. Lower quality diesel fuel can produce less power and can also damage the generator.
• Air quality: The quality of the air that the generator is operating in can also affect its output. Operating a generator in thin air or in hot weather can reduce its output.
• Maintenance: Proper maintenance of a diesel generator is essential to ensure its optimal performance. A generator that is not properly maintained may produce less power and may also be more likely to break down.

Here are some examples of the power outputs of different types of diesel generators:

• Small portable generator: 1-5 kW
• Medium-sized generator: 5-10 kW
• Large generator: 10-100 kW
• Industrial generator: 100 kW and up

The power output of a diesel generator is an important factor to consider when choosing a generator for a particular application. The generator should have enough power output to meet the needs of the devices and appliances that will be connected to it.

It is also important to note that the power output of a diesel generator is not the same as its efficiency. The efficiency of a diesel generator is the percentage of the fuel energy that is converted into electrical energy. A more efficient generator will produce more electrical energy for a given amount of fuel.

Diesel Generators

Diesel generators are a type of backup or standby power source that uses a diesel engine to generate electricity. These generators are widely used in various applications where a reliable and continuous power supply is crucial. Here are key aspects related to diesel generators:

Components of Diesel Generators

1. Diesel Engine:
   • The diesel engine is the primary component responsible for converting diesel fuel into mechanical energy. This mechanical energy is then used to turn a generator to produce electricity.
2. Generator (Alternator):
   • The generator, or alternator, converts the mechanical energy from the diesel engine into electrical energy. It consists of a rotor and a stator, and as the rotor turns within the stator’s magnetic field, it induces an electric current.
3. Fuel System:
   • The fuel system stores and delivers diesel fuel to the engine for combustion. It typically includes a fuel tank, fuel pump, and fuel injectors.
4. Cooling System:
   • Diesel generators have a cooling system to maintain optimal operating temperatures. This system may include a radiator, cooling fans, and a water or air cooling mechanism.
5. Exhaust System:
   • The exhaust system is responsible for expelling the combustion gases produced during the diesel engine’s operation. It usually includes a muffler and may incorporate emission control devices.
6. Control Panel:
   • The control panel houses the generator’s control and monitoring systems. It allows operators to start or stop the generator, monitor performance, and sometimes control other parameters such as voltage and frequency.
7. Voltage Regulator:
   • The voltage regulator maintains a stable output voltage by adjusting the excitation current to the generator’s rotor.
8. Battery Charger:
   • Diesel generators often have a battery or set of batteries to start the engine. A battery charger ensures that the batteries remain charged and ready to start the generator when needed.
9. Automatic Transfer Switch (ATS):
   • An ATS is a crucial component for standby generators. It automatically switches the electrical load from the main power source to the generator when it detects a power outage and vice versa when the main power is restored.

Working Principle:

1. Combustion: Diesel fuel is injected into the combustion chamber, and the heat generated by the compression of air ignites the fuel.
2. Mechanical Energy: The combustion process produces high-pressure gases that expand, creating mechanical energy. This energy is used to rotate the engine’s crankshaft.
3. Electricity Generation: The rotating crankshaft is connected to the generator, causing it to spin. As the generator’s rotor rotates within the stator, it induces an electric current, generating electricity.

Applications:

1. Emergency Power:
   • Diesel generators are commonly used for emergency backup power in critical facilities such as hospitals, data centers, and telecommunications facilities.
2. Construction Sites:
   • They are used on construction sites to power tools and equipment where a reliable grid connection may not be available.
3. Industrial Facilities:
   • Diesel generators provide backup power for industrial plants and manufacturing facilities to prevent production disruptions.
4. Remote Locations:
   • In remote or off-grid locations, where a stable power supply from the grid is not feasible, diesel generators can provide a reliable source of electricity.
5. Mining Operations:
   • Diesel generators are often used in mining operations to power equipment in remote and rugged environments.
6. Agriculture:
   • Farms may use diesel generators to power irrigation systems, machinery, and other agricultural equipment.

Advantages:

1. Fuel Availability:
   • Diesel fuel is widely available, making diesel generators suitable for various locations.
2. Fuel Efficiency:
   • Diesel generators are known for their fuel efficiency, providing a cost-effective solution for standby power.
3. Durability:
   • Diesel generators are generally robust and durable, capable of handling heavy loads and providing long service life.
4. High Torque:
   • Diesel engines provide high torque, making them suitable for applications with varying load conditions.

Limitations:

1. Noise and Emissions:
   • Diesel generators can be noisy, and their combustion process produces emissions. However, advancements in technology have led to quieter and more environmentally friendly models.
2. Maintenance:
   • Regular maintenance is essential to ensure the proper functioning of diesel generators.
3. Initial Cost:
   • Diesel generators may have a higher upfront cost compared to some other types of generators.

Diesel generators are a reliable and widely used solution for providing backup or primary power in various settings. The choice of a diesel generator depends on factors such as power requirements, environmental considerations, and the specific needs of the application.

Diesel generators are machines that convert the chemical energy of diesel fuel into mechanical energy, which is then used to generate electricity. They are a popular choice for a variety of applications, including prime power for remote locations, backup power for businesses, and emergency power for hospitals and other critical infrastructure.

Diesel generators are available in a wide range of sizes, from small portable generators that can be used to power a few appliances to large stationary generators that can power entire buildings or even small towns.

Diesel generators are typically powered by four-stroke diesel engines. Diesel engines are known for their reliability and fuel efficiency, making them a good choice for applications where long-term operation is required.

Diesel generators work by burning diesel fuel in the engine, which drives a generator to produce electricity. The electricity generated by the generator can then be used to power lights, appliances, and other electrical devices.

Diesel generators are a valuable source of backup power in the event of a power outage. They can also be used as a primary source of power in remote locations where there is no access to the electrical grid.

Here are some of the benefits of using a diesel generator:

• Reliable: Diesel generators are very reliable and can operate for long periods of time without any problems.
• Fuel-efficient: Diesel generators are fuel-efficient, which can save you money on operating costs.
• Durable: Diesel generators are built to last and can withstand harsh operating conditions.
• Versatile: Diesel generators can be used in a variety of applications, from prime power for remote locations to backup power for businesses and critical infrastructure.

If you are considering purchasing a diesel generator, be sure to do your research and choose a generator that is the right size and type for your needs. You should also consider the cost of fuel and maintenance when making your decision.
