Design And Control Of Permanent Magnet Synchronized Generator

Abstract

Normally wind mill system is erected in areas where there is more wind flow. Sometimes the velocity of wind may be increased or decreased. When the velocity of the wind is increased or decreased, the speed of rotation of the leaf is also increased or decreased. This may affect the constant power production. This project is developed for producing constant power even if there is change in the velocity of wind. A synchronizing motor is inertly connected with the generator. The wind sensor senses the velocity of the wind and sends signal to the microcontroller. Accordingly, the microcontroller controls the synchronizing motor through driver unit. If the velocity of wind is increased, the speed of the synchronizing motor is increased (in reverse direction) to reduce the speed of the generator. Also if the velocity of wind is decreased, the speed of the synchronizing motor is decreased (in reverse direction) to increase the speed of the generator. Thus the generator is working with constant speed.
