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.
