结合供电管理部门提出的“利用人工神经网络进行大型电力变压器故障诊断的研究”科研课题中遇到的实际问题，针对ＢＰ网络及其算法本身的缺陷，提出新的改进方法，并应用于解决工程中的实际问题。计算结果证明了这种办法的有效性和实用性。
Combined with the practical problems encountered in the scientific research project “Research on fault diagnosis of large power transformers using artificial neural networks” proposed by the power supply management department, aiming at the defects of the BP network and its algorithm itself, a new improved method is proposed and applied to solve the problems of engineering In the actual problem. The calculation results prove the validity and practicability of this method.
