摘要
由于大功率电力电子器件的电磁兼容问题还没有很好解决,变流机组在同时需要高品质的交流电和直流电的混合供电船舶中还占据举足轻重的地位。由于目前相关仿真研究还较少,变流机组的运行工况比较复杂,是系统仿真的难点之一,根据变流机组在船舶电力系统的运行特点和要求,建立了变流机组电机模型和励磁系统模型,仿真结果表明该模型比较准确地模拟了变流机组各种工况下的运行特性,说明数学模型和仿真方法正确,为设备的进一步设计分析与完善提供参考,同时为系统分析提供了一定的基础。
Because of the still existing EMC problem of high - power power electronic element, converter unit is still used as an important equipment on ships requiring high quality AC＆DC supply systems, Because of the special structure, various running patterns and complex operational control, the converter unit system is difficult to be simulated, and therefore, there is rare simulating study on it. On the basis of the performances and requirements of the operating converter unit embedded in a ship＇s power system, a complete set of mathematical models for the unit, including machine models and excitation system models, are established. The results of the simulation indicates that the models are fairly accurate in simulating operational behaviors of converter unit under various working conditions, which testifies the validity of the model and provides reference for further analysis and improvement of the equipment. It also sets up the foundation for the analysis of the whole power system .
