Abstract

The invention discloses an abnormal traffic detection device of an energy internet information support network, which realizes identification of abnormal traffic by performing traffic sampling, feature extraction and classification on the information support network. According to the method, frequency-domain features of uplink traffic and downlink traffic data between a server and a core switch are extracted based on a wavelet packet analysis theory, an energy Internet information support network traffic time-frequency domain mixed feature set is constructed, and an artificial bee colony optimized support vector machine is used as a classification model. According to the device, support is provided for accurate and rapid verification of traffic anomaly and security situation awareness of the communication network of the intelligent substation and guarantee of stable operation of an information physical tight coupling power system.
