| 摘 要： | 为研究定子绕组形式对同步发电机励磁绕组匝间短路稳态电流特征的影响,对一台12 kW、6极同步发电机的定子绕组连接进行了不同形式的变换,利用经过实验验证的多回路分析法分别对不同定子绕组形式的电机所发生的同一种转子匝间短路故障进行了计算,通过傅里叶分解得到了稳态故障电流的谐波特征,并进行了比较分析。计算与分析表明,发生励磁绕组匝间短路故障后,电机定、转子电流会出现不同于机端外部短路、定子内部短路等其它故障的稳态电流谐波特征,且不同定子绕组形式的电机表现的特征也各不相同。对励磁绕组匝间短路故障监测与保护的研究,需建立在科学的故障计算基础上,对不同型号的电机都需具体分析计算,根据实际情况选择用来检测或保护的特征量。

| Abstract: | In order to find out the effects of stator winding configurations on steady-state currents characteristics of field windings under inter-turn short circuits in synchronous generator,stator windings connections of a 12 kW synchronous generator with six poles were changed for several different configurations to calculate the same fault based on the multi-loop method which had been verified by experiments,then through FFT analysis the steady-state currents characteristics were achieved and on which a comparati... |
