THE MAGNETIC ELECTRICITY GENERATOR AND ITS APPLICATION IN WIND TURBINES

Abstract

A permanent magnet synchronous generator (PMSG) is a device that converts mechanical energy to electrical energy. Permanent magnet generators generate electricity with the inside magnets that can be used to power other electric devices. A PMSG is a generator, where the excitation field is provided by a permanent magnet instead of a winding coil. In this generator/device the rotor windings have been replaced with permanent magnets. Its rotor is consisting of the permanent that generates a field for excitation and replaces the external supply source for the generator. In most of power generation plants, the synchronous generator is used. Now days synchronous generator is used in all types of turbines for e.g. steam turbine, gas turbine and hydro turbine etc. The Permanent Magnet Generator uses the magnetic field generated by a permanent magnet to convert mechanical energy into electrical power. It can be able to generate an AC current, with which it can able to power the whole engine and charge the battery. This study helps to understand the working and application of Permanent Magnet Generator in a windmill turbine.
