Abstract
With the rapid development of power system,500 kV extra high voltage transmission lines put forward higher requirements for relay protection.Traditional methods are faced with technical challenges such as slow action speed and insufficient reliability.In this paper,artificial intelligence is introduced into 500 kV line protection,and an intelligent relay protection system based on deep learning is designed.The system comprehensively uses intelligent algorithms such as convolutional neural network and long-term and short-term memory network to build a layered and cooperative protection architecture.Experiments show that the system can achieve millisecond fault detection,and it is excellent in fault classification accuracy and adaptability to complex working conditions.
