摘要： Electrical distribution networks (9) are provided between an electrical power source (10, 42, 43, 50, 65) and electrical loads (11, 12, 13) in the form of a number of connections (A to G). Faults can occur within the electrical distribution network (9) resulting in fault electrical currents which may damage the network (9). An electrical protection arrangement comprises fault current flow detectors (A' to G', AA, BB, AAA to DDD) in a hierarchy of levels defined by cascades of connections it is possible to utilise a controller to actively trip a circuit breaker associated with a respective fault current flow detector (A' to G', AA, BB, AAA to DDD). In such circumstances by considering the level response from each fault current flow detector (A' to G', AA, BB, AAA to DDD) against a threshold, typically in a binary format, the controller determines by sequential movement along a fault path (31, 62) at which level in the hierarchy of levels the circuit breaker should be tripped to isolate parts of the electrical distribution network (9). Generally, the lowest level within a hierarchy of levels is tripped to isolate the minimum amount of the electrical distribution network (9) leaving the remainder of the electrical distribution network (9) operational.

摘要： A hybrid power system for an aircraft comprises a gas turbine connected to a generator for generating electrical power; an electrical storage device configured to output electrical power; a propulsor; a motor operable to drive the propulsor using electrical power from either or both of the generator and the electrical storage device; and a controller. The controller, to meet a propulsor power demand, is configured to control (i) an amount of electrical power generated by the generator, and (ii) an amount of electrical power outputted by the electrical storage device. In a first control mode coinciding with an increase in the propulsor power demand sufficient to cause a transient excursion of the operating point of a compressor of the gas turbine from a steady state working line, the controller is further configured to temporarily increase the amount of electrical power outputted by the electrical storage device such that the transient excursion is reduced.
