| 英文摘要: |
In this paper, the rough set theory and neural network technology are applied to transformer fault diagnosis, through reduction algorithm with rough set reduction as the pre-unit of neural network.
duction algorithm and its implementation are discussed in detail.
e actual training data and test results show that rough set reduction algorithm reduces the number of input samples, improves the training speed and efficiency and accuracy of fault diagnosis.
conclusion, the application of rough set reduction algorithm to fault diagnosis system of power transformers is feasible and effective. |
