摘要
就BP网络的不足,提出了一种改进的BP神经网络模型,用于汽轮发电机组故障的诊断。经理论和实践证明:该方法有效地提高了故障诊断的精度和可靠度,为旋转机械故障诊断提供了有效方法。
As for the deficiency of BP network, this paper suggests an improved BP nerve network model which can serve in breakdown diagnose of tubine generator set. Proved theoretically and practically, this method increased efficiently the precision and reliability of breakdown diagnose, and provided efficient way for breakdown diagnose of whirling machinery. Figs 2, tables 4 and refs 7.
