Abstract

The invention discloses a data mining method of the neural network based on nearest neighbor clustering. An improved nearest neighbor clustering learning algorithm is used to train the neural network, so that on the premise that the precision requirement is met, the number of nodes of a hidden layer is reduced, the network structure is simplified, the learning speed of the neural network is increased, and the learning efficiency and precision of the neural network are further improved; and further data mining is carried out on the neural network, and the mining efficiency for a database of a large practical power system via the neural network is further improved. The data mining method aims at ensuring the safe, stable, high-quality and economical operation of the power system, and satisfying higher requirements for mass data of the digital power system and reliability, consistency and sharing performance of data.
