Design and Simulation of Windturbine Integration with Grid using Converter Topology

Abstract

The electrical power generated by using wind energy to drive wind turbine. This mechanical power can be converted into electrical power by using induction generator. Induction motor is operated as an induction generator and generates variable voltage variable frequency output. AC output of an induction generator will be fed to converter consist of uncontrolled rectifier and single phase inverter. But in this paper variable voltage source is considered as the AC output of Induction generator. So simulation was carried out considering varying source voltage with open loop control. Buck converter with SG3525 PWM Controller is used to stabilize the DC link constant. Arduino Microcontroller Programme is developed for SPWM method to trigger the gate pulses of Single Phase Inverter. These entire system is simulated on simulation software package. Hardware prototype model will be developed and integrated to the grid or feed to the load.
