The Modeling And Real-time Simulation Of Ship Electric Power System Based On XPE

As the key part of the ship electric power training system, ship electric power real-time simulation system is very strict about the real-time performance except for the basic requirement for the manipulation function of electric power training.Although the dynamic behavior of ship power station can be simulated by using MATLAB graphical modeling simulation tool, the real-time performance of the system is hard to be guaranteed. To solve this problem, based on the real-time simulation technology of RTW, this paper implants the precise timing function into the C++ code which is transformed by the ship power station model. Based on the C++ code, the unction of the ship electric power real-time simulation model can be realized. The main content of this paper is as follows:1. According to the function need of the ship electric power real-time simulation system, the ship power diesel generator model and ship power system model are build by using Matlab/Simulink. The function of ship electric station starting, adjusting load as well as parking and the function of ship power system can be simulated well with the good dynamic features.2. By using RTW real-time simulation technology, the ship electric power model is converted into C++ code which can be analyzed in order to separate the needed real-time treatment code.3. To meet the XPE (Windows XP Embedded) system demand, by means of the high precision timing of C++, the timing way meeting the demand of timing precision is implanted into the C++ code transformed from ship electric power simulation model. Therefore, the MATLAB model code which has no real-time characteristic can be have the good real-time performance.It is showed by tests that ship electric power simulation model based XPE converted by RTW has the good correctness, real-time performance and high reliability.
