Enhancement low-voltage ride through capability of permanent magnet synchronous generator-based wind turbines using interval type-2 fuzzy control
TLDR
In this paper, a lowvoltage ride through (LVRT) scheme for the permanent magnet synchronous generator (PMSG) variable speed wind turbine at grid faults is proposed, where the machine side converter controller is used to control the dc-link voltage using interval type-2 fuzzy logic control.Abstract:
Increased penetration level of the wind power generation has brought new issues and challenges of power quality. One of these issues is low-voltage ride through (LVRT). This study proposes an LVRT scheme for the permanent magnet synchronous generator (PMSG) variable speed wind turbine at grid faults. The machine side converter controller is used to control the dc-link voltage using interval type-2 fuzzy logic control taking into account the non-linear relationship between the generator speed and the dc-link voltage. Under grid faults, there is a power mismatch between the generated active power and the active power delivered to the grid. This excess power is stored in the generator inertia to keep the dc-link voltage constant. To validate the proposed control strategy, simulation results for 1.5 MW PMSG-based wind energy conversion system are carried out by MATLAB-Simulink under symmetrical and asymmetrical faults.read more
