A Novel Approach to Power Quality Assessment: Real Time Hardware-in-the-Loop Test Bed

A novel approach to power quality assessment based on real-time (RT) hardware-in-the-loop (HIL) simulation is proposed. The RT-HIL platform is being used for power quality studies of NAVY all-electric ships. The sensitivity for power quality deviations of a variable speed drive controller card was tested in the platform. The successful experiment has contributed to the conceptual design of a universal power quality test bed, which would have the function of testing the immunity of electric components and equipment and the consequent impact on ac distribution systems.
