To cope up with challenges of power demand and supply gap it’s essential to deal with the advancement in the field of renewable energy with highest potential. In country like India where the power sy stem restructuring and advancement in energy sector is taking rise in recent years, so it’s great opportunity to have a system with the isolated operation due to variations in the geographical conditions. In this work a wind mill technology with the isolated operation is presented of 8.5kW, for residential purpose. The direct drive PMSG (permanent magnet synchronous generator) type of generator is used, which is suitable for the variable kind of wind speed. A performance of the PMSG is studied under the different wind speed conditions with the adequate control mechanism. As due to change in the speed of wind the voltage and current changes, these variations are avoided by means of adjusting the control signal PWM provided to the buck boost converter. With the lead acid battery a constant DC voltage level is maintained at the input terminals of inverter.
