一种新型感应电动机调速装置—控制模型

A NOVEL ADJUSTABLE SPEED EQUIPMENT FOR INDUCTION MOTOR DRIVES—CONTROL MODEL

新型感应电动机的恒转矩控制装置,经实验和现场运行证明它能用于中、大功率、低同步转速感应电动机拖动风机类和许多非风机类负载系统。本文用定磁场控制原理,论述了感应电动机控制模型和去耦控制方法;最后,提出了整个控制系统线路方案。

A novel adjustable speed equipment of constant torque for indu- ction motor drives have been proved in Lab.and practice that can suit for fans or centrifugal pumps of mechanical loads and lots of non-fan pumps of mechanical loads in the middle and high power range. This paper develops a control model and decoupled control me- thod of induction motor on the principle of Field Oriented Control. In the end,the control configuration of full system is presented.
