Modeling and Simulation of Fault Processing in Helicopter Power Supply System
Instrumentation, Measurement, Computer, Communication and Control（2012）
摘要
With more electrical equipment adopted in helicopter, structure and management of helicopter power supply system becomes more and more complicated, so automatic fault processing function has been widely used in power supply system. As it needs long development cycle and high cost to design power supply system, this paper establishes digital models of voltage/frequency detection module, GCU, TRU, BTB, SSPC and Fault Produce module in power supply system and accomplishes simulation of automatic short circuit fault processing in DC and AC subsystem with MATLAB/SIMULINK. The fault waveform analyses validate that modeling methods of helicopter power supply system is accurate and effective.
