同步电机励磁装置避免误投的方法

Method of Avoiding Excitation by Mistake in Synchronous Motor Excitation Device

同步电机广泛应用于冶金、水利、石化、建筑、矿山、电力等工业领域,完善的励磁控制系统是其不可缺少的重要部分。本文通过对众多泵站的多种励磁控制系统应用状态研究以及对大量故障诊断分析,指出现有励磁装置产生误投的原因,并提出了改进方案。

Synchronous motors are widely used in metallurgy,water conservancy,petrochemical,construction,min- ing,electric power and other industrial fields.Perfect excitation control system is an indispensable part of the mo- tors.In this paper,through the research on the application status of various excitation control systems in many pumping stations and the analysis,of a large number of fault diagnosis,the causes of misoperation of existing ex- citation devices are pointed out and the improvement scheme is put forward.
