We develop an efficient snapshot algorithm that needs no control messages and does not require channels to be first-in-first-out. We also show that several stable properties (e.g., termination, deadlock) can be detected with uncoordinated distributed snapshots. For such properties, our algorithm can be further simplified.
The more-electric aircraft (MEA) is one major trend for future aircraft. With increased number of power electronic converters (PECs) and electrical loads, the system performance and the power management for on board electrical loads are therefore key issues and need to be addressed during the design process. The increased amount of PECs makes the… (More)
This paper investigates application of dynamic phasors for accelerated study of electric power system dynamics. Four different modelling techniques are applied to simulate the example system that includes synchronous generator, transmission line and load, under both normal and faulty operation. Effectiveness of dynamic phasor concept for electric power… (More)

Starting an aircraft engine with an electrical machine has been one of the major trends for future aircraft. This paper studies the stability of a permanent-magnet machine (PMM) based aircraft starter/generator (S/G) system. Using control-to-output transfer functions, the stability analysis of this S/G system is thoroughly studied. The impact of the key… (More)
