NASA AREAL Testbed and UE Power Quality Testing

A large number of electrified aircraft propulsion systems currently in development consist of high-voltage direct current (HVDC) power systems and utilization equipment (UE). There is a need for industry consensus standards and guidelines in order to support the development and verification of these rapidly maturing systems, user equipment, and associated technologies. To support the aforementioned need, the National Aeronautics and Space Administration (NASA) Revolutionary Vertical Lift Technology (RVLT) Project is performing ongoing power quality testing on HVDC power systems and associated UE. The testing described in this paper describes the UE testing completed to date in the NASA Advanced Reconfigurable Electrified Aircraft Lab (AREAL).
