大型异步电动机起动过程的机-网暂态仿真软件研究

Research Software on Machine Network Transient Simulation of Large Capacity Squirrel Motor Starting

建立了集中耦合参数的电网模型和状态方程的电动机数学模型。利用该模型进行仿真，可以得到电动机起动过程中的电流、电压、磁链、传速等值。开发了电网与电动机的接口。利用该接口，用户可以建立自己的电动机模型并编制仿真程序，和已有的网络程序接口。

Mathematical model on power network and squirrel motor is established.A free interface between network and machine is created.simulation results shows the software is effective on machine network transient research.
