Real-time Deep Neural Networks for internet-enabled arc-fault detection

A method and an apparatus (90) detect series and/or parallel arc faults in AC (50) and DC (40) systems. The method according to one embodiment inputs an AC current signal (S201); extracts a fundamental component (S204, S211) of the AC current signal and monitors an amplitude variation profile for the fundamental component, thereby generating a first arc fault detection measure; detects non-stationary changes (S207, S214) in the AC current signal by applying at least one measure of order higher than one, thereby generating a second arc fault detection measure; and determines (S217, S221) whether an arc fault exists based on the first arc fault detection measure and the second arc fault detection measure.

The proposed system has a plurality of generator systems, each generator system having an alternating current generator directly connected to a rectifier. The alternating current generator is rotationally coupled to a prime mover, wherein, upon operation of the prime mover, the alternating current generator produces an alternating current output , is de-synchronized to further ones of the plurality of generator systems and has a variable generator speed. The rectifier directly connected the alternating current generator is adapted to convert the alternating current output of the alternating current generator into a direct current output. A direct current distribution bus is coupled to the direct current outputs from each of the rectifiers. The system further has a plurality of inverters adapted to receive power from the direct current distribution bus, the output of each inverter being adapted to drive an alternating current motor.

Power distribution system and method thereof

A power generation and distribution system utilizes two or more AC generators each of which may be driven by a separate prime mover such as a turbine. The generators may be driven at different rotational speeds. AC power from the generators may be rectified and applied to a common DC bus. Electrical loads may be applied to the common bus and may establish an electrical power requirement. Allocation of electrical power requirement may be made among the generators based on power available from the turbines.
