摘　　要：针对船舶电力负荷中的电动机,给出了基于变阻抗负荷数学模型的新概念,提出了新的电动机仿真模型.利用Simulink提供的模块构造仿真模型,并进行了计算机仿真,给出了全压及星三角起动过程的定子电流、转矩等仿真曲线.仿真结果符合实际起动的情况,同时也验证了所建模型的正确性.A new concept of variable impendent for induction motor is presented for the induction motor, and the new mathematic model of the motor is put forward. The simulation model is constructed with model supplied by Simulink, and simulation is carried out to obtain stator current and torque simulation curves during full voltage and star-triangle starting process. The result corresponds to the situation of practical starting process, and also proves correctness of the simulation model.
