矿井提升系统的稳定校正

Correction for the Stability of Mine Hoisting System

在用于矿井提升的发电机—电动机系统中存在着由于发电机励磁饱和引起的自持振荡 ,这种自振现象必须控制在允许范围内 ,否则将留下安全隐患。本文论述了将稳定变压器作为校正环节 ,用以限制该系统自振幅值 ,使其保持在技术条件允许的范围内 ,以保证该系统的稳定性。

In the generator motor system for hoisting in mine exists self sustaining oscillation caused by the excitation saturation of generator.This self sustaining oscillation must be controlled within permissible range,otherwise it will leave hidden troubles for safety.This paper discussed the stabilizing transformer as a corrected link,which was used to restrict the range value of the self sustaining oscillation of the system and keep it in the permissible range of technical conditions so as to guarantee the stability of the system.
