Description
Summary:Wind energy is an inexhaustible clean energy source. However, its cost is still too high to compete with traditional fossil sources. The yield of a conversion system depends on different parameters: the power of the wind, the conversion system curve and the generator ability for responding the fluctuations in the wind. In this paper, a sensorless controller based on Doubly-Fed Induction Generator (DFIG) mathematical model and vector control using MPPT strategy is presented. The proposed control can directly ensure the position speed via simple mathematical equation by measuring the stator voltage, the rotor and stator currents. The principle of speed estimation is described and simulated by using Matlab/Simulink software. The simulation results demonstrate the feasibility of the control strategy based on the measurement of the output power and it is offered to maximize the power delivered to network despite all the parameter changes via MPPT strategy.
