This work presents an efficient control strategy for low voltage ride through (LVRT) and maximum power tracking of a permanent magnet synchronous generator (PMSG) based variable speed grid connected wind turbine generator. Three-level Neutral Point Clamped converters are connected back to back to perform the power conversion. A controller is proposed and implemented for the machine side converter to maximize the power generation and loss minimization under varying wind speed. A controller is also proposed and implemented for the grid side converter to transfer the generated power to a local load and grid by keeping the DC link voltage constant. To test the LVRT capability, a three phase short circuit fault is applied on the grid side. The real time digital simulator results on a 2 MW/4 kV PMSG verify the effectiveness and superiority of the proposed control scheme under different loading and fault conditions.
