surge voltage

In this paper, the harms of voltage jump and harmonics are emphatically along with precautions against them.

在多种因素的干扰下,会导致电力的诸如电压变异(较长时间的变异和瞬间突变)、非正弦畸变、三相失去平衡等质量问题,本文着重论述了电压突变和谐波的成因、危害及防护对策。

The stator winding open-circiuted and supply voltage sudden change through a real example and the simulation results are also analyzed here.

根据单相永磁同步电动机在d-q-o坐标系下的动态数学模型,编写计算机仿真程序,通过实例对双值电容异步起动单相永磁同步电动机的两种非正常运行过程:电源电压突变、定子绕组断路进行仿真计算,并对仿真结果进行分析。
