摘　　要：本文运用Matlab/Simulink建立了船舶电力推进系统的数学模型,并对船舶电力推进系统的高机动特性进行了数字仿真。在建模和仿真的过程中,本文采用了分层结构和模块化设计方法,并采用了基于转差频率调速控制策略,对异步电动机的起动过程、加载过程中的电动机转速、电磁转矩、三相电流以及dq轴电流进行了详细仿真分析。此外,在两种常见工况下,分别比较了采用转差频率调速控制策略和不采用该策略时电机的转速变化曲线,仿真结果证明了所建立的模型和仿真方法的准确性和有效性。This paper proposes to establish a mathematical model of marine electric propulsion system via Matlab/Simulink,and carries out simulation on high mobility feature of the system.A hierarchical structure and modular design is adopted in the process.Based on the control strategy of slip speed regulation,the paper analyzes the motor speed,electromagnetic torque,three-phase current and dq-axis current in starting and loading process of the asynchronous motor through simulation.Under two common working conditions,the speed change curves are compared under the condition of using the slip speed regulation control strategy and without using the control strategy.The simulation result proves the correctness and effectiveness of the simulation model and method.
