摘　　要：变流机组是交直流混和供电舰船的重要设备,它结构特殊、运行控制复杂,是系统仿真的难点之一,在电力系统仿真的文献中很少有关于其仿真方面的报道,为此根据变流机组在交直流混和供电系统的运行特点和要求,建立了一套完整的数学模型:电机模型,控制模型和网络模型,并给出了仿真实现方法,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,它为整个交直流供电系统的分析提供了一定的基础。Converter unit is an important equipment in AC＆DC supply systems of ship. Because of its special structure and complex operational controls, it is one of those points in power systems, which are difficult to handle in simulation. There has been rare discussion of its simulation in all the available literatures about simulation of power systems. According to its characteristics and operational requirements in AC＆DC supply system, a complete set of mathematical models for converter unit were established, which include machine models, control models, and network models. The methods of conducting its simulations were proposed The results show that the models are fairly accurate in simulating operational behaviors of converter unit under various working conditions, which provide certain foundation of analysis of the whole AC＆DC supply system.
