Résumé

In grid-connected wind conversion systems,
traditionally control characterizes by fixed gain Proportional
Integral Derivative (PID) regulators. Conventional PID control
laws provide good results in case of linear systems with constant
parameters. In heather land, these control laws are limited in
robustness and effectiveness especially in cases of non linear
systems. However, in electrical system control, robustness is of
particular very importance. This paper investigates the
performance of fuzzy logic controllers (FLCs) applied in gridconnected wind generator to improve performances of control.
This purpose needed to achieve good performances of reactive
power (Q) compensation. This work at first presents a simple
control algorithm for active (P) and reactive power based on PI
controllers in which an inverter designed can synchronize a
sinusoidal current output with a voltage grid. The controller
feeds maximum active power into grid at unity power factor,
whereas it also allows the adjustment of reactive power injected
into the grid. In the second phase of the study, FLCs changes PIs
regulators for improve performance of power control. Simulation
results confirm that the intelligent control system has good
performances.
