摘要
通过对短路匝磁势进行傅里叶分解得到各次谐波分量,各次谐波分量在定转子绕组中产生附加谐波电势。认为定子绕组中1/2次谐波电流和励磁绕组中的3/2次谐波电流可作为判断发电机转子是否存在匝间短路的依据。
Resolves the magnetic potential of rotor’s short circuited wind into harmonic waves by Fourier Transform,which cause harmonic electric current in the winds both of rotor and stator.Considers that the 1 /2th harmonic current in stator wind and the 3 /2th harmonic current in rotor wind might be the criterion for knowing whether the short circuit detection of generator rotor’s wind is existing.
