As the important support of the national economy, the safe operation of the power grid provides an endless motivations for the economic development. At the same time, the safe operation of the transmission lines is facing increasing challenges. To master the real-time state of transmission line, an intelligent monitoring system for the recognition of the hazards of transmission line, which is based on the theory of depth learning, is proposed. The monitoring system mainly includes： signal-acquisition equipment, the optical network, server control center, as well as the display terminal. The transmission line hazards intelligent identification algorithm which is in the server and control center, is the core of the system. First, the recognition algorithm uses characteristics by the sparse self-coding to train the neural network. Second, it employs the operator of convolution and pooling for feature dimension reduction. Finally,the softmax regression is utilized to solve the problem of hazard classification. The experiments confirm that the hazards identification algorithm based on deep learning, hazards can be accurate to discriminate. Then, the results will be transferred to computer terminal to fully control the whole operation, and all kinds of emergencies can be handled in time to ensure the safe operation of the power system.
