摘　　要：提出基于感应电动机的出厂数据(如额定功率、额定功率因数、最大转矩倍数和转子转速等)估算适用于电力系统机电暂态仿真的电动机单笼模型参数的方法。该算法充分考虑了电动机的转矩–滑差物理机制特性,其收敛特性好、鲁棒性强。通过计算15台实际电动机的单笼模型参数,分析它们的电磁转矩–滑差特性,并与其出厂数据值进行对比,结果表明,根据算法计算的模型参数用于模拟电动机的机电暂态特性具有较高的精度,证明了算法的有效性。最后通过动模实验与数值仿真对比,进一步验证了所提算法的有效性和适用性。An algorithm to estimate the single-cage model parameters of induction motors for power system electromechanical transient simulation is based on the routine manufacture data： rated power, rated power factor, maximum torque, rotor speed, etc. The proposed method considers the torque-slip characteristics of induction motors, and has good convergence and robustness. The single-cage model parameters of 15 actual induction motors are calculated and tested through analyzing and comparing their torque-slip physical mechanical characteristics with the manufacture data. For further verifying the effectiveness and adaptability of the proposed method, the numerical simulation results using single-cage models are compared with the physical simulation experiment results using the actual induction motors.
