Simulation and Evaluation of High-Voltage Power Systems for Civil Aircraft

摘要

A status report of the modelling and simulation work that is being undertaken as part of the TIMES (Totally Integrated More Electric Systems) project is presented. Dynamic power quality simulations have been used to asses the performance of the electrical system of a EMA-based actuation system for an Airbus A330-size aircraft, for both low-voltage 115 V, and high-voltage 230 V three-phase AC systems. The high-voltage system is shown to have benefits in terms of power quality and reduced size and weight of equipment.
