Electricity transmission, generation and distribution | PPT

The document discusses distribution systems. It defines distribution systems as the part of the power system that distributes electricity from substations to consumers. It then classifies distribution systems based on factors like voltage level (primary vs secondary), current type (AC vs DC), construction method (overhead vs underground), and

Electricity generation, distribution and transmission | PPT

A distribution substation transfers power from the transmission system to the distribution system of an area. It is uneconomical to directly connect electricity consumers to the main transmission network, unless they use large amounts of power, so the distribution station reduces voltage to a level suitable for local distribution.

What is electric power distribution?

Electric power distribution is the portion of the power delivery infrastructure that takes the electricity from the highly meshed, high-voltage transmission circuits and delivers it to customers. Some also think of distribution as anything that is radial or anything that is below 35 kV.

What matrices are used in electrical distribution networks?

• Features of electrical distribution networks • Ill-conditioned Jacobian matrix in Newton-Raphson method • Power flow calculations in distribution systems • Forward/Backward sweep method • Kirchhoff’s formulation • BIBC & BCBV matrices • Dist-flow formulation • Linearized Dist-flow formulation • Extension to three-phase systems

What are the components of a distribution line?

The key components of distribution lines are identified as feeders, distributors, and service mains. AC and DC distribution are further explained, including methods to obtain 3-wire DC systems. Various connection schemes like radial, loop and interconnected are also summarized along with their advantages and disadvantages.

What is the main function of a distribution substation?

Voltage transformation: The primary function of a distribution substation is to reduce the voltage down to the distribution voltage level. In Figure, only one transformer is shown. Other substation designs will call for two or more three-phase transformers. There are many “standard” distribution voltage levels.
