Fault Simulation of Aircraft AC Power System Based on Bi-enabling Petri Net

Combined with fault injection method, Bi-enabling Petri Net model is proposed for fault simulation of Aircraft AC Power System. In the new model, add fault input and state-transition set to the traditional Petri net system, redefine the transition rules, and give its relation matrix description. Then, based on the relation matrix, a dynamic algorithm is proposed to establish the Bi-enabling Petri Net model of the components. Finally, through sharing composition of Petri net, get the integral model of AC Power System. Examples and simulation results show that this model can achieve the real-time control of AC BUS output and simulate the impacts of fault disturbances under various power configurations.
