An Improved Vector Control Integrated DPC Scheme for Effective Ride Through of PMSG during Grid Distortions

When a Permanent Magnet Synchronous Generator (PMSG) is linked to the utility grid and operating under grid disturbances, the grid side active and reactive power, grid currents and DC link voltage will have pulsations. The controller design must be taken into account to minimize these pulsations in grid side power and DC link voltage. This study proposes a simple Vector Control (VC) integrated Direct Power Control (DPC) method for calculating the power pulsations in a grid-connected PMSG when the grid is distorted. To verify the effect of grid distortion in a 2.5kW, the tool used is PSCAD/EMTDC.
