| 摘 要： | 为了进一步完善交直流调速技术,提高电力传动系统的调速性能,针对电力传动系统中存在的电机及拖动机械的耦合振动问题,分别从传动机构中的机械非线性与系统变流装置具有的电气非线性角度对系统中的非线性机电耦合现象进行了机理分析研究,这一结论为制定合理的振动控制策略奠定了可靠的研究基础.结果表明,内因和外因的相互作用是造成电力传动系统非线性机电耦合振荡的根本原因.

| Abstract: | In order to futher perfect the AC and DC speed-governing technology and improve the speed-governing performance of power drive system, in light of the coupled vibration of electric machine and drag machine in power drive system, the mechanism of nonlinear electromechanical coupled oscillation is analyzed as viewed respechvely from the mechanical nonlinearity in drive and the electrical nonlinearity in coverter control system. This kind of analysis and research is beneficial to making the reasonable strategy of vibration control. |
