基于Simulink的船舶电力系统仿真研究

针对传统用C++语言编写船舶电力系统模型的方法较为复杂的特点，将 Simulink仿真与C++语言相结合，建立船舶电力系统基本模型。根据Simulink仿真发电机模块与算法的特点，结合模拟训练中实时性的要求,对基本模型进行改进，构建两种适用于不同算法的船舶电力系统仿真模型。仿真结果表明，定步长算法下的仿真模型可满足模拟训练实时仿真的要求；变步长算法下的仿真模型结合多项式拟合算法，可得到与实时仿真基本相同的结果。因此，两种仿真模型均适合于基于模拟训练的船舶电力系统。

Real-time Simulation of Ship Power System with Simulink

The traditional method to build the ship power system model with C++ language is somewhat complex, so Simulink and C++ were combined to build the basic model. On the basis of the characteristics of the model and the algorithm in Simulink simulation and the requirements for real-time performance in simulation training, two different algorithms of ship power system models were constructed with the improvement of the basic model. The simulation results show that the model with fixed step size algorithm can meet the requirements of real-time simulation training, and the model with variable step size algorithm, combined with polynomial fitting algorithm, can get basically the same results as the real time simulation. Therefore, simulation models are both suitable for real-time simulation in ship power system simulation training.
