矿井提升系统有给定自持振荡分析

AN ANALYSIS OF MINEHOISTING SYSTEM WITH SETTING SELF-SUSTAINED OSCILLATION

在采用发电机－电动机组合的矿井提升系统中，由于发电机励磁饱和非线性变化，将引起系统的自持振荡；自持振荡的严重程度是与系统各环节的元件配置和参数确定相互制约和密切关联的，也就是说，要使自持振荡稳定在允许范围之内，就必须要求系统有一组合理的元件和参数与之相匹配，这就是研究自持振荡的目的所在。本文研究矿井提升系统有给定条件下的自持振荡，它与本刊第１４卷第３期发表的“矿井提升系统无给定自持振荡分析”相对应，构成了对于矿井提升系统有、无给定自持振荡研究的完整体系。这一研究成果，对于矿井提升系统的设计和应用无疑是大有稗益的。

Due to a nonlinear variation of generator in saturation magnetization, a self-sustained oscillation will occur in the mine hoisting system with combined generator andmotor. The extent of the self-sustained oscillation is mutually constrained by and closelyrelated to both elements configuration and parameters determination of the mine hoistingsystem,in other words, keeping a self-sustained oscillation within allowable limits needthat the system is provided with a gruop of matchable elements and rational parameters,inwhich the aim of the self,sustained oscillation study lies. Pairing up with the paper titled “An Analysis of Mine Hoisting System Without Set-ting Self-sustained Oscillation”(in Mining Research&DeveIopment, Vol. 14, No.3),this paper can compose a complete system on the study of mine hoisting system witborwithout setting self-sustained oscillatioh. Undoubtedly,the resuIts of study are very usefulto the design and operation of the mine hoisting system.
