摘要
船舶电力系统一般分为发电、配电、输电、用电4个部分。通过研究各部分的运行机理后在MATLAB软件的Simulink环境下,利用模块化的方法,建立了柴油机及其调速系统、发电机励磁系统以及功率负载的仿真模型,进而搭建起船舶电力系统的仿真模型。通过对船舶电站暂态稳定性的特点进行分析,对船舶电力系统的正常运行以及发生的故障的情况进行了仿真并得到仿真结果。结果反映了船舶电站在正常和故障2种状况运行时电网上各部分以及发电机组的电压、电流运行情况,比较准确地反映实际运行中暂态稳定的过程。
Ship power system consists of generation, distribution, transmission, and use.By studying the running mechanism of each part and using modular approach, the simulation models of a diesel engine and its speed regula-ting system, generator excitation systems and power loading are established in the MATLAB/Simulink envirinment. On this basis, the ship power simulation system is built up.Through analysis of the ship power transient stability, the characteristics of the normal and failure operations of the ship power system are simulated.The simulation re-sults reflect the voltage and the current operating conditions under normal and failure opeation states of ship power stations, which actually show the process of transient stability during actual operation.
