Simulation system model of independent power-supply based on reusable object-oriented technology

The research of Prognostic and Health Management (PHM) for Independent Power-supply System (IPSS) is an important step to ensure the safety for the complex system of moving devices. The simulation platform for IPSS is a powerful tool for these study works. In this paper, the structure and function of IPSS were analyzed first, and the weakness of existing simulation system were pointed out, then a development method based on the reusable object-oriented technology for IPSS simulation platform was presented. The simulation software model for IPSS was described by Use case Diagram, Class Diagram and Activity diagram of UML (Unified Modeling Language). And failure mode description was designed in class library of simulation model, which made it easy to develop simulation program integrating with modeling and fault simulating for different IPSS. With the proposed method, a simulation program for an aircraft power system was developed, which steady-state simulating and fault transient simulating had been realized. The validity of the developed system model is verified by the experimental results.
