摘要:
 摘要:为了研究双馈风力发电机转子静偏心故障和转子绕组匝间短路故障频谱特性的区别,避免
静偏心导致对转子绕组匝间短路故障的误诊断。依据有限元理论,建立双馈风力发电机转子绕组
匝间短路模型和计及静偏心的模型,对转子绕组匝间短路、计及静偏心的转子匝间短路故障进行了
仿真。以转子线电流和定子线电压为研究对象,从频谱特性角度,对各组的仿真结果进行了对比研
究。分析结果表明,静偏心的存在会导致定子线电压中出现与转子绕组匝间短路故障相同的特征
频率,可能导致误诊断;同时对转子线电流和定子线电压以及定子线电压的高频段进行监测,能够
有效区分静偏心与转子绕组匝间短路故障,避免静偏心导致对转子绕组匝间短路故障的误诊断。
Abstract:
 Abstract:Differences of doubly-fed induction generator(DFIG)spectral characteristics between rotor
windings inter-turn short fault and rotor static eccentric were studied,in order to avoid misdiagnosis of ro-
for windings inter-turn short fault leading by rotor static eccentric. Based on the finite element theory,
model of rotor windings inter-turn short fault and the model considering static eccentric were built,and
these different situations were simulated. Taking rotor line current and stator line voltage as research ob-
jects,the simulation results for each group were compared from the perspective of spectral characteristics.
The results show that the presence of static eccentric can cause the same frequency as rotor windings in-
ter-turn short fault in stator voltage,it may cause false diagnosis. While monitoring rotor line current,
stator line voltage and high frequency of stator voltage could distinguish between rotor static eccentric and
rotor windings inter-turn short fault effectively,and avoid misdiagnosis of rotor windings inter-turn short
fault caused by rotor static eccentric.
