In airplane power distribution systems, dc bus voltages are expected to rise as electri cation efforts push power demands higher. Higher bus voltages improve system effciency and reduce the weight of the cabling system. Despite these advantages, electric arcs become a signi cant threat in aircraft when the higher voltage is operated at altitude. Arcs can occur either in series or in parallel with a load. Parallel arcs become near short circuits that release immense energy and pose a severe hazard to aircraft. The onboard Fault Management System (FMS) needs to be able to react quickly and accurately to these high energy faults to ensure system survivability. Series arcs also need to be detected and isolated by the FMS, but the additional series arc impedance results in a load current decrease. Without proper detection methods, this fault can be mistaken for a load transient since the current still falls within normal operating limits. This thesis gives an overview of the key components and objectives of a Fault Management System. This includes an introduction to various fault detection algorithms, fault isolation schools of thought and recon guration strategies used in modern microgrids. Further focus will be given for how the FMS must handle the series arc fault at each stage of the arc timeline. First, series arc modeling is discussed. Impedance-based prevention is then proposed by utilizing a novel arc energy accumulation mechanism to estimate the critical re-ignition energy. Lastly, optimal detection threshold selection and effcacy will be addressed.
