摘要
对三相绕组Y接法单相电容电动机的瞬态过程进行仿真分析。为了得到瞬态特性,提出了三相绕组Y接法单相电容电动机在αβ坐标系下的瞬态数学模型,并通过实例对该电动机的瞬态过程进行仿真计算,对仿真结果进行了分析。该电动机能否在最小不平衡条件下运行,与电容的数值密切相关。用对称分量法分析了三相绕组单相电容电动机最小不对称运行时需要满足的条件,并由此初步计算电容的数值,然后通过计算机仿真较准确地加以确定电容的数值。
The transient analysis of tri-winding single-phase capacitance motor with star-connected,introducing the math model of single-phase operation of three-phase induction motors with the star-connected in αβ coordinate to get the transient property was presented in this paper.MATLAB language was used to develop the computer simulation program.The program was applied to emulate transient process of tri-winding single-phase capacitance motors with star-connected through example.Symmetrical components method was employed in the analysis the minimum asymmetrical operation condition of tri-winding single-phase capacitance motors with star-connected.Emulation results were also studied here.
