Abstract :
The more-electric aircraft concept is a fast-developing trend in modern aircraft power systems and will result in an increase in electrical loads fed by power electronic converters. Finalizing the architectural bus paradigm for the next generation of more-electric aircraft involves extensive simulations ensuring power system integrity. Since the possible number of loads in an on-board power system can be very large, the development of accurate, effective and computational time-saving models is of great importance. This paper focuses on development of a modeling approach based-on functional representation of individual power system units. This provides for possibility of fast simulation of a full generator-load power system under both normal and fault conditions. The paper describes the modeling principle, illustrates the acceleration attainable and shows how the functional representation can handle fault scenarios.
