Abstract
This project presents an advanced control strategy for the operation of a direct-drive synchronous generator- based stand-alone variable-speed wind turbine. The control strategy for the generator-side converter with maximum power extraction is presented. The stand-alone control featured is constant output voltage and frequency that is capable of delivering to variable load. The main attention is dc link voltage control deals with the chopper control for various load condition.And also a battery storage system with converter and inverter has to be used to deliver continuous power at the time of fluctuated wind.The simulation results show this control strategy gives better regulating voltage and frequency under sudden varying load conditions. Dynamic representation of dc bus and small signal analysis are presented. The dynamic controller shows very good performance.
