摘　　要：针对发电机定子局部放电故障,提出了基于DSP+ARM双核的风电机组状态监测系统,对发电机局部放电信号进行实时在线监测。给出了系统硬件和软件的设计方案,为上位机进一步诊断和预测风电机组的故障提供可靠的数据。结果表明,能够良好的、有效的对发电机绝缘状况进行故障诊断。For partial discharge fault of generator stator, this paper proposes a state monitoring system of dual-core wind generator, based on DSP ＋ ARM, so as to make real-time on-line monitoring of the local discharge signal of the generator. It also presents the hardware and software design schemes, to provide reliable data for further diagnosis of upstream PC and for prediction of wind generator fault. The results show that the system is good and effective to make fault diagnosis of generator insulation.
