PMG Based Wind Energy Conversion System with Closed Loop Boost Converter
Journal Title: Bonfring International Journal of Power Systems and Integrated Circuits - Year 2012, Vol 1, Issue 1
Abstract
This paper presents a system in which a wind Permanent Magnet Generator (PMG) feeds an isolated load through a Closed Loop Boost Converter (CLBC). The output voltage and frequency of the PMG is variable in nature due to non uniform wind velocities. The fluctuating output is rectified and kept constant by means of a boost converter. The boost converter is provided with a closed loop feedback control, which is designed using a PID controller. In this converter, the output voltage is continuously sensed and duty ratio of the switch is varied to maintain a constant DC output voltage. This converter output is converted to single phase ac using a single phase PWM inverter, which employes PWM unipolar switching to control the output voltage and current. A three-phase ac source, based on a-b-c reference frame is used to simulate the performance of this system. The power converters together with independent control systems can effectively improve the output voltage and frequency of the wind PMG feeding an isolated load.
