A power quality enhanced for the wind turbine with sensorless direct power control under different input voltage conditions

Introduction. The quality of electrical energy is essential during disturbances, at the level power electronic devices will suffer serious operating problems causing dangerous damage. Aim. A new approach to direct control without grid voltage sensor improves and instantaneous active reactive converters. Methodology. First, technique network with a based on switching table, which classic approach, discussed its performance analyzed under increasing decreasing load. In addition, proposed also same circumstances their compared. Originality. method consists nonlinear modulated controller conventional guarantees very good results in polluted network. verified using MATLAB/Simulink. Results. simulation different input conditions show that not only has tracking power, but reduces current total harmonic distortion 1.9 %, lower than requirement for operation.
