Investigation of small PMSG based wind turbine for variable wind speed

In order to investigate small wind turbines, a comprehensive knowledge of mechanical and electrical parameters is required. Permanent Magnet Synchronous Generator (PMSG) is one of the kinds which are widely used for variable speed and direct driven wind power generating. In order to predict the amount of power that can be extracted by the wind turbine in a concerned area the knowledge of wind speed pattern for that particular location is required. In this paper a case study is selected to study the wind pattern and investigate the performance of the PMSG based wind power generation system for fixed speed and variable speed conditions. Wind power generation system simulated using MATLAB / Simulink consisting of wind turbine, PMSG, diode rectifier, Maximum Power Point tracking (MPPT) controlled boost converter, and DC load is considered. The Hill Climbing Search (HCS) algorithm is implemented using Fuzzy Logic Controller (FLC) for MPPT. The effectiveness of PMSG based wind power generation in the case study is investigated with the environmental conditions recorded at BITS-Pilani, Hyderabad campus, Telangana, India.
