Aim to dealing with prognosis health management for electrical equipment or electrical control system, a fault modeling platform which uses the method of directed graph is presented in this paper. At first, hierarchical framework is taken into consideration to represent the relationship of electrical apparatus within a system, the fault topology model is derived based on directed graph with object oriented programming is proposed as design rules, after that, the fault modeling platform is developed based on hierarchical structure, and fault analysis is regarded as main purpose. Secondly, method of decision making is discussed to realize reasonable inference system for the fault model, fault propagation algorithm using fuzzy computation and probability of fault influence degree is proposed and studied based on the developed platform. Finally, power supply system for aerospace is given as a practical example to show the feasibility and validity of the platform.
