摘要
船舶电力系统是一个独立系统,当负载变化时将引起电网电压的剧烈波动。为了研究船舶电力系统在负载变化时的稳定性,利用Matlab/Simulink建立了船舶电力系统的仿真模型,包括同步发电机模型、励磁系统模型、柴油机及调速器模型和负载模型。通过对同步发电机在单机运行状态下突加、突减负载等不同工况进行动态仿真和分析,得到系统参数的变化情况。仿真结果符合"MLT-STD-1399 300章"规定的船舶电力系统界面的电压瞬变特性,为我国船舶电力系统的研究提供了参考依据。
The marine electric power system is an independent system,which can cause the fierce fluctuation of the power grid voltage when its load is varied. In order to research the stability of marine electric power system when its load changes,the simulation model of the system was established by means of Matlab/Simulink,in which the synchronous generator model,excitation system model,diesel engine and speed regulator model,and load model are included. The parameters variation conditions of the system were obtained by dynamic simulation and analysis for the synchronous generator in the single generator operation at different working conditions of sudden load increase or decrease. The simulation results accord with the voltage transient characteristics of the marine electrical power system interface defined in＂300 Section in MLT-STD-1399：AC Power＂,which provides the reference basis for research on marine electric power system in China.
