Modeling and design of a micro wind energy system with a variable-speed wind turbine connected to a permanent magnet synchronous generator and a PWM rectifier

This work proposes a methodology to design a micro wind energy conversion system (μWECS) based on the steady state characteristics of the wind turbine, permanent magnet synchronous generator (PMSG) and PWM rectifier. The aerodynamic control behavior is analyzed and included in the modeling procedure since it influences the system operation modes. The aerodynamic control limits the power at the generator axis in order to properly operate the system. This type of power limitation poses constraints to an optimized design of the WECS and is considered in the proposed methodology. The steady state and dynamic models of the employed wind turbine, PMSG and power converter are presented with a detailed systematic procedure to analyze the system. A complete WECS simulation model is presented and the obtained simulation results are used to validate the results.
