Transmission and Distribution Electrical Engineering

Electric power transmission , the tools and means of moving electricity far from where it is generated, date back to the late 19th century. They include the movement of electricity in bulk formally called " transmission " and the delivery of electricity to individual customers " distribution ". In the beginning, the two terms were used interchangeably. Prior to electricity, various systems had been used for transmission of power across large distances. Chief among them were telodynamic cable in motion , pneumatic pressurized air , and hydraulic pressurized fluid transmission. Pneumatic transmission was used for city power transmission systems in Paris, Birmingham, Rixdorf, Offenbach, Dresden and Buenos Aires at the beginning of the twentieth century. Cities in the 19th century also used hydraulic transmission using high pressure water mains to deliver power to factory motors.

Transmission and distribution refers to the different stages of carrying electricity over poles and wires from generators to a home or a business. The primary distinction between the two is the voltage level at which electricity moves in each stage. After electricity has been generated, a system of electrical wires carries the electricity from the source of generation to our homes and businesses. It refers to the part of electricity delivery that moves bulk electricity from the generation sites over long distances to substations closer to areas of demand for electricity. Transmission lines move large amounts of power at a high voltage level — a level that is too much to be delivered directly to a home or business. Explore the history and value of the transmission system. In most cases, the power moving through the transmission system must be reduced to lower voltage levels by electricity distributors before it can be delivered to a residence or business.

Such system studies necessitate a thorough understanding of network parameters and generating plant characteristics for the correct input of system data and interpretation of results. A background to generator characteristics is therefore included in Section 1. It is now recognized that harmonic analysis is also a major system study tool. This is discussed separately in Chapter Reliability studies are considered in Chapter The analysis work, for all but the simplest schemes, is carried out using tried and proven computer programs. The application of these computer methods and the specific principles involved are described by the examination of some small distribution schemes in sufficient detail to be applicable to a wide range of commercially available computer softwares.

Premium Membership. Learn from experienced power engineers. The purpose of the electric transmission system is the interconnection of the electric energy producing power plants or generating stations with the loads. A three-phase AC system is used for most transmission lines. The operating frequency is 60 Hz in the U. Electrical energy, being a very convenient form of energy, has become fully pervasive in the modern world.

Electric power distribution is the final stage in the delivery of electric power ; it carries electricity from the transmission system to individual consumers. Distribution transformers again lower the voltage to the utilization voltage used by lighting, industrial equipment and household appliances. Often several customers are supplied from one transformer through secondary distribution lines. Commercial and residential customers are connected to the secondary distribution lines through service drops.
