摘要
本文将复数力矩系数法推广用于多机系统HVDC引起的轴系扭振问题分析,并导出了完整的数学模型.通过对一多机ac/dc系统阻尼特性的研究,阐明了HVDC引起发电机轴系扭振的机理及直流控制参数和方式对轴系扭振的影响.文章还将复数力矩系数法和特征根分析法的结果进行了比较说明二种方法的一致性.
In this paper, the complex torque ccofficient analysis method is popularized to analyse
the HVDC-caused shaft torsional oscillations in multimachine system. the complete sys-
tem model is deduced. By analysid or thr damping characteristics of a multimachine ae/de
system, the mechanism of the HVDC-caused thaft torsional oscillations and the effccts of
de control manners and parameters on thec HVDC-caused shaft torsional oscillauons are
expiained. The comparison between the complex torque ecofficient method and the
eigen-analysis method is carried out, the same results are obtained.
