磁阀式电机软起动装置的研制

Development of Magnetic Saturation Controllable Soft Starter for Motors

本文提出一种新型磁控电机软起动方案,在电动机定子回路串入磁阀式可控电抗器来实现电机的软起动,能保证电动机在负载要求的起动特性下平滑起动,有效地降低对电网系统的冲击。用MATLAB进行了仿真,并与实际波形比较分析。

A new scheme of magnetic control for the soft starting of motors is introduced in this paper. Magnetic saturation controllable reactor is connected in series with stator of the motor to realize soft start. It can make the motor start smoothly according to the starting characteristic required by the load, and reduce the strike to the power system. Emulated results by MATLAB are compared with the real waves.
