| 摘 要： | 电动机定子绕组单相接地故障是发电机最常见的一种故障,而且往往是更为严重的绕组内部短路故障发生的先兆.本文提出一种在电磁暂态分析软件PSCAD/EMTDC环境中对电动机单相接地故障进行仿真的方法,该方法运用电力系统仿真软件以单相接地故障的数学模型代替实际电力系统,用数值方法对系统进行试验和研究.该模型不仅可以对发电机故障的瞬态和稳态过程进行仿真,而且能够揭示发电机故障瞬态的运行特征及瞬态过程中各个故障量的变化规律.仿真结果表明该方法可以大大降低内部短路故障的发生几率,减少故障造成的损失,从而验证了EMTDC电动机模型和算法的有效性和正确性,为电动机故障诊断和保护的深入研究提供了有效的仿真平台.

| Abstract: | The stator winding single-phase grounding malfunction of motor is one of the most common generator error which often is the sign of the more serious winding internal short problem.This paper proposes a simulation method for motor single-phase grounding in PSCAD/EMTDC software environment.This method uses a mathematical model of single-phase grounding malfunction in the place of real power system,then tests and stuy the system with numerical method.This model can not only simulate the transient state process... |
