The structures and basic performances of different phase locked loops (PLLs) are investigated and compared regarding how the PLLs can cope with grids that contain both the positive and negative sequence components and/or even non-periodic disturbances. The delayed signal cancellation (DSC) technique is tested by simulation and experiments. A modified cascaded DSC is developed and tested in laboratory.
