摘　　要：针对传统阻感性负载无法满足船舶辅机设备对船用变频启动器启动性能和功率考核的要求,提出一种基于电力电子负载概念模拟电机特性的负载模拟系统。并依据电机本体模型及数学数值计算方法,根据实时仿真技术,将电机动态数学模型转换成可由数字控制器(比如DSP)实时运算的数值运算模型。最后,通过MATLAB/simulink仿真和实验,证明了模拟电机特性的电力电子负载的可行性。The traditional inductive impedance load cannot meet the requirements of the marine auxiliary equipment on the starting performance and power checking of the frequency converter. It is presented a kind of load simulating system with motor characteristics simulation based on the power electrical load concept. On the basis of the motor model and the mathematical numerical calculation method, according to the real-time simulation technology, the dynamic mathematical model of the motor can be converted into the numerical calculation model calculated in real-time by the digital controller （e.g. DSP）. Finally, through MATLAB/simulink simulation, it is proved the feasibility of power electronic load based on motor characteristics simulation.
