Tracking Control of the Maximum Power Point (MPPT) In A Small Wind Turbine (SWT) For Isolated Residential Applications
Authors: , , , ,
Abstract: This work shows the design, analysis, simulation and implementation of a tracking control Maximum Power Point (MPPT) in a Small Wind Turbine (SWT) with fixed angle α. The MPPT controller extracts the maximum available kinetic energy of the wind V, which is converted to mechanical power Pm by the wind rotor shaft, followed by an electrical power Pe . Permanent Magnet Synchronous Generator, (PMSM), and a current three-phase rectifier alternating AC-DC, direct current, voltage Vr generated converter is regulated by a reducer to DC-DC optimal load to maintain a deep cycle battery, using a Proportional Integral controller (PI) and equations relate V, Mn, Vr and angular velocity of the wind rotor W optimizing the output voltage Vr * to maintain maximum energy extraction from the wind at any speed and load demand. A DC-DC boost converter with a PI controller and DC-AC inverter provides AC voltage with low harmonic distortion for residential applications.
