Abstract:

This paper presents modeling, analysis, and simulation of a variable-speed wind turbine control. Wind turbine emulator (WTE) based on induction motor (IM) is used to provide a controlled environment for wind power generation system control testing. The permanent magnet synchronous generator (PMSG) is tied to the grid via back-to-back converters. The aim of the study is threefold: the development of the WTE, extracting the maximum power, and feeding captured power to the grid. The methods of maximum power point tracking (MPPT) using Fuzzy logic is used to maximize the wind power capture at different wind speeds. The grid-tied inverter controlled by the fuzzy-PI controller is used for transferring power to the grid and maintaining DC-Link voltage constant. Simulation results performed on the Matlab/Simulink environment, verify the performance of the different control strategies and the usefulness of the approach.<
