Parts of a diesel generator and their functions.

We all know that a diesel generator is used as a source of backup when supply of power is not constant. They have assumed great importance and have almost become a necessity for households and companies in areas where there is a shortage of electrical supply. Given the promising nature of a diesel generator, we all have at some point used it or at least have known its merits. But have we ever tried to understand what are the various parts that power the diesel generator and help it function?

Let us look at some of the main components of a diesel generator and their functions:

1.       Engine – The heart of the system

The function of the engine is to create the mechanical energy that the diesel generator converts into electricity. The design of the engine is aimed at generating a maximum supply of electrical current by running on diesel or other alternate fuels.

2.       A comprehensive fuel system

Generators that run on diesel or any other fuel, have a fuel system that stores and pumps it to the engine. The tank stores a good amount of fuel to power the generator for several hours at a stretch. A fuel pipe in the system connects the tank to the engine while a return pipe connects the engine to the fuel tank for the return of fuel. A fuel pump moves fuel from the tank through fuel pipe and to the engine. There is a fuel filter which filters out debris from the fuel, if any before delivering it to the engine. A fuel injector atomizes and injects the fuel directly into the combustion chamber of the engine.

3.       An alternator

The alternator in a diesel generator converts mechanical energy produced by the engine into electrical current. It comprises of the stator and the rotor (or armature). The stator is stationary and contains a set of coils that conduct electricity. The rotor moves to create a constantly rotating electromagnetic field around the stator.

4.       Voltage Regulator

The alternator may generate electrical voltage but the level of voltage needs to be regulated that is suitable for practical use. Voltage regulator is an electrical regulator that maintains a constant level of voltage.

5.       Impeccable cooling and exhaust systems

The temperature of a diesel generator must be regulated to prevent overheating while being used. Generators can use a fan, coolant or both to control the temperature of the generator at work. The internal combustion engines are usually cooled by passing engine coolant through the engine block. The generator also produces exhaust as the combustion chamber converts fuel. There are exhaust systems that dispel harmful gases emitted.

6.       Lubrication system

A diesel generator comprises of various moving parts. These parts need to be oiled for their smooth functioning. The lubrication system ensures that the parts are well oiled and functioning at their best.

7.       Acoustic Enclosure

Being a mechanical product with many moving parts, a diesel engine makes lot of noise during its operation. In order to control the noise emission, the engine and alternator assembly is housed in a soundproof canopy having sound absorbent material from inside. As per Central Pollution Control Board (CPCB), the maximum noise emission from a generator should not exceed 75 dBA from 1 m distance from the canopy.

Difference Between Blackout and Brownout.

When it comes to electricity flow, things aren’t black and white always. However, they can be termed as black or brown. It is possible that you know of a blackout in the past, but have you experienced a brownout? And what is the difference between the two phenomena?

A blackout can be defined as a complete loss of power affecting many users of electricity spread throughout a large area over an extended span of time. Residents and businesses lose electricity power and the entire area experiences a blackout.

A brownout is bit different in the sense it is a somewhat measured power reduction or loss of electricity to pockets of consumers. Brownouts can be caused due to the state of ‘poor power quality’ in which utilities may reduce line voltage to deliver more electricity for increased power demand. Factory equipment that requires a stable supply of energy can be severely damaged or even destroyed due to these voltage fluctuations.

Brownouts can cause issues with electrical devices that function on certain specific voltage levels, like computers. On the other hand, blackouts denote major equipment failure or weather related issues leading to a complete loss of electric power.

Sometimes, rolling blackouts are put into place by power companies to balance out an increase in power demand that cannot be met by the existing system output. The demand for electricity can be increased by heat waves and prompt the requirement for a rolling blackout.

HOW CAN YOU PREVENT THESE VOLTAGE FLUCTUATIONS?

Sadly, there are only a few ways to avoid this situation. In case you absolutely need to keep your equipment running always, you could consider power backups.

An intense upsurge in electricity demand does not occur often, but if you want to ensure that your business is geared for any possible threats, it is worth investing in dg sets lest you may be left out in the dark.

Indian Power Scenario 2013

Electric energy occupies the top grade in energy hierarchy. It finds innumerable uses in home, industry, agriculture and even in transport. The fact that electricity can be transported practically instantaneously, almost pollution-free, at the consumer level and that its use can be controlled very easily, makes it very attractive as compared to other form of energy.

The per capita consumption of electricity in any country is; index of the standard of living of the people in that country. As per the latest figures, the annual per capita consumption of electrical energy in some of the countries is: USA—11,920 kWh, Canada— 16,020 kWh Japan—6,750 kWh, UK- 5,467 kWh, Russia-6,017 kWh and India – 498 kWh in 2012.

The electric energy demand in India during the past 20 years was higher than the gross generation as a result 
of which there were massive power-cuts. Monsoons are another reason for the increase in these power cuts. The load-shedding has been in force for the last several months as the water level in reservoirs depleted drastically due to deficient rainfall last year. There are several issues that characterize India's energy scenario today. These can be briefly listed as follows:

The present installed capacity in our country is about 225.133 GW as on May 2013 and the largest share in power generation is contributed by thermal power plants, which account for about 78.7 percent of the total power generated in country. Hydel power contributes about 18.5 percent while nuclear power accounts for only 2.7 percent. The rest being accounted for by diesel, wind, solar and gas plants.

In December 2011, over 300 million Indian citizens had no access to electricity. Over one third of India's rural population lacked electricity, as did 6% of the urban population. Of those who did have access to electricity in India, the supply was intermittent and unreliable. In 2010, blackouts and power shedding interrupted irrigation and manufacturing across the country.

The problem of rising power cuts can be resolved by adopting the following technologies which have been invented for the same purpose:

One type of technology includes inducting micro-turbines using natural gas that could enable individual households and shops to generate their own power cheaply, keeping grid as a backup.

Another such technology would be the construction of a Km long tower with saline or brackish water being poured from top so that as it hurtles down, the water reaches velocity of 70 km/h, good enough to drive turbines and generate electricity. Apart of this electricity would be used to pump water up and the remaining be utilized for consumption. Another device that could be used is a UPS (also called an inverter); a power storage device is a silent solution to power cut problems.
