| 摘 要： | 在分析交交变频器-多相同步电动机调速系统运行的基础上,提出将多相同步电动机的d、q轴变量分解为低频分量(含非周期分量)和高频分量分别加以处理,并忽略转子回路对高频分量的电阻和阻尼绕组对低频分量的作用的分析方法,建立了适合于交交变频器-多相同步电动机系统稳态和似稳态分析的等效电路模型.试验结果证明了该模型的正确性.

| Abstract: | This paper proposes a new analysis approach for analytic study of the cycloconverter-fed multiphase synchronous motor, based on the analysis of its operation characteristics. That is, the d-and q-axis variables of multiphase synchronous motor are decomposed to low-frequency components (including aperiodic components) and high-frequency components, which can be treated separately. In this case, the resistance of rotor circuits to high-frequency components and the effect of damper winding on low-frequency components are negligible. And the equivalent circuit model of cycloconverter-fed multiphase synchronous motor system for steady-state and quasi-steady-state analysis is established. The experiment results are provided to verify the validity of the equivalent circuit model. |
