【摘要】 针对大功率潜水电泵用大功率三相异步电机运行时的启动问题,基于坐标变换可以推导出在(d,q)两相旋转坐标系下的大功率三相异步潜水电机的动态数学模型,将Matlab/Simulink中的基本模块和Sfunction结合,构建大功率三相异步潜水电机的仿真模型,同时对该模型在全压启动电压下进行仿真分析。仿真分析结果表明,全压启动具有足够大的启动转矩,能够保证大功率三相异步潜水电机的正常启动。更多还原

【Abstract】 To the start - up problem of the three - phase submersible motor for high - power pump,dynamic mathematical model for three - phase asynchronous submersible motor can be derived in the two-phase rotating reference frame(d,q) on the basis of coordinate transformation.This paper combines the basic module of MATIAB/SIMULINK with S -function,structuring the simulation model for three -phase asynchronous motor,and emulation analysis for it in the voltage of line starting.The simulation results demonstrate that line starting has large starting torque enough to guarantee that the three - phase asynchronous three - phase submersible motor for high - power can start normally.更多还原
