Extra High Voltage Transmission Line

ABSTRACT

Power system is the fencing of the entire electrical power network in the whole world. It consists of generation, transmission and distribution. Power system is the primary part in the electrical power system from where electrical energy is generated. Power station is responsible only for generation of the power. Electrical energy is transmitted through national grid from the power station to different substation and then to the consumers with various designs of transmission lines.

Transmission lines are of two types: Underground cables and Overhead transmission lines. Generally, transmission lines are the main components come after generation in the electrical power system. For the smooth operation and efficient transmission of the power, many factors are to be considered for the transmission line design. Design of inter connecting transmission line deals with frequency, phases, voltage and also diameter, area of cross-section, length, resistance, inductance, capacitance etc.

Here in this project will be made to design a transmission line using C-language because C-language has many advantages over other computer languages. It is one of the most versatile and powerful computer language ever developed and easy to understand.

Turbo Alternator

Introduction:

An alternator is an electromechanical device that converts mechanical energy to alternating current electrical energy.

In principle, any AC electrical generator can be called an alternator. Generally large alternators in power stations which are driven by steam turbines are called turbo-alternators.

TYPES ON THE BASIS OF CONSTRUCTION:

1. Salient Pole Type: Hydro Generators

2. Non Salient Type: Turbo Alternator

APPLICATIONS:

Turbo alternators are high speed alternators among all other alternators ever developed and are

used in all thermal power stations e.g., gas power stations, steam power stations, nuclear power

stations etc. Their generating ranges are from 30MW-1000MW depends upon capacity

requirement.

Turbo Alternator:

These are the high speed machines among all other alternators which are driven by steam turbines and gas

turbines. They have maximum speed of 3000 rpm. They can generate up to 1000MW.
