| Abstract |
The aim of this paper is to propose a solution set to
improve the converter behaviour for the system perturbations. A
current controller of VSCs connected to the grid through an
LCL-filter is presented. The proposed algorithm controls the
grid current using only two sensor sets. Other variables are
obtained with a state estimator, and the possible disturbances of
the system are attenuated with active damping. Besides, other
algorithms complementary to the current controller are
presented. The control algorithms have been tested by
simulation for different disturbances, such as temporal
variations in the components of the model and perturbations in
the grid, and also with linear and non-linear models of the
converter. |
