Primary Sources of Electrical Energy
We can produce electrical energy by converting different energies available in nature. So we should look into various natural sources of energy which we use to produce electricity. Some common sources of energy are The Sun The Wind The Water Head The Fuel The Nuclear Energy Out of five above listed sources of energy we…

Electric Power Generation
We divide the power system into three parts; power generation, transmission, and distribution. In this article, we will discuss power generation. Actually, in power generation, one form of energy gets converted into electrical energy. We produce electrical energy from various natural sources. We classify these sources into two types renewable sources and non-renewable sources. In…

What is MHD Generation
The MHD generation or, also known as magneto hydrodynamic power generation is a direct energy conversion system which converts the heat energy directly into electrical energy, without any intermediate mechanical energy conversion, as opposed to the case in all other power generating plants. Therefore, in this process, substantial fuel economy can be achieved due to…

Power Plant: What Are They? and types
What is a Power Plant? A power plant (also known as a power station or power generating station), is an industrial location that is utilized for the generation and distribution of electric power on a mass scale. Many power stations contain one or more generators, a rotating machine that converts mechanical power into three-phase electric…

Types of DC Generators
DC generators are classified based on how their fields are excited (i.e. produced). There are three methods of excitation, and thus three main types of DC generators: Permanent Magnet DC Generators – Field coils excited by permanent magnets Separately Excited DC Generators – Field coils excited by some external source Self Excited DC Generators – Field coils excited…

Working Principle of DC Generator
Before we can explain the working principle of a DC generator, we need to cover the basics of generators. There are two types of generators–DC generators and AC generators. Both DC and AC generators convert mechanical power to electrical power. A DC generator produces direct power, while an AC generator produces alternating power. Both of…

Parallel Operation of DC Generators
In modern power system, power is usually supplied by many synchronous generators connected in parallel which helps to maintain continuity of plant operations. Now a day’s, isolated one large generator is outdated. When we connect two generators in parallel, they have a tendency to remain in step. By doing some changes in their armature current…

Construction of Alternator
The construction of an alternator consists of field poles placed on the rotating fixture of the machine. An alternator is made up of two main parts: a rotor and a stator. The rotor rotates in the stator, and the field poles get projected onto the rotor body of the alternator. The armature conductors are housed…

Working Principle of Alternator
The working principle of an alternator is very simple. It is just like the basic principle of DC generator. It also depends upon Faraday’s law of electromagnetic induction which says the current is induced in the conductor inside a magnetic field when there is a relative motion between that conductor and the magnetic field. For…

Alternator Synchronous Generator
What is an Alternator? An alternator is defined as a machine which converts mechanical energy to electrical energy in the form of alternating current (at a specific voltage and frequency). Alternators are also known as synchronous generators. Where is an Alternator Used? Alternators produce the power for the electrical systems of modern vehicles. Previously, DC generators or dynamos were…
