摘要: An SA (Substation Automation) system based on IEC 61850 is an intelligent substation; it has been receiving considerable attention as a core component of smart grid. The explosive increase threats to cyber security expanded critical national infrastructures including the power Substation Automation also become main target cyber-attacks. Currently, various countermeasures such firewalls, IDS (Intrusion Detection System)s, and anti-virus solutions have developed, but date, these not sufficiently reflected inherent features 61850. This study suggests method anomaly detection for MMS (Manufacturing Message Specification) GOOSE (Generic Object Oriented Events) packets, communication protocols Automation. 3-Phase preprocessing, EM (Expect Maximization), one-class SVM (Support Vector Machine) techniques are applied. effectiveness suggested evaluated through experiments.
