摘要: 针对油田三相异步电动机控制精度低、响应速度慢,及基本的SVPWM( Space Vector Pulse Width
Modulation) 计算时间长且计算量大等问题,提出一种改进的SVPWM 的控制算法。通过旋转部分扇区的参考矢
量,计算扇区1 和扇区6 的作用时间,从而节省计算其他扇区的作用时间,简少了计算量。通过搭建异步电机
的矢量控制模型,针对抽油机上的负载特性进行仿真分析,结果验证了其转速跟踪性强,超调较小,磁链振荡
小,尤其对负载突变的应用场景具有一定的优越性。

Abstract: An improved SVPWM( Space Vector Pulse Width Modulation) control algorithm is proposed for the oil
field three-phase asynchronous motor with low control precision,slow response,and large calculation of basic
SVPWM calculation time. The fan is calculated by rotating the reference vector of some sectors. The action time
of the zone 1 and the sector 6 save the calculation of the action time of other sectors and simplify the calculation
amount. By constructing the vector control model of the asynchronous motor,the simulation analysis of the load
characteristics on the pumping unit verifies that the speed tracking is strong,the overshoot is small,and the flux
linkage is small,especially for the application scenarios with sudden load changes it has certain superiority.

Key words: three-phase asynchronous motor, vector control, improved space vector pulse width modulation
( SVPWM) control algorithm
