摘要
基于多回路数学模型,对异步电动机定子绕组匝间短路故障瞬变过程做了数字仿真,并完成了相关物理实验。在此基础上,对定子绕组匝间短路故障的典型特征进行灵敏度与可靠性评定,遴选出定子负序视在阻抗低通滤波值这一可靠兼具良好灵敏度的定子绕组匝间短路故障特征,从而为定子绕组匝间短路故障的灵敏、可靠检测奠定了基础。
The transient numeric simulation and relevant experiments of stator winding inter-turn short circuit fault of asynchronous motor are conducted using multi-loop mathematic model. Based on the simulation and experimental results, the sensitivity and reliability of the typical fault features of stator winding inter-turn short circuit are evaluated. It is concluded that the low-pass-filtered stator negative sequence apparent impedance is the most robust and reliable fault feature.
