摘要：

Major blackouts are rare events, but their impact can be catastrophic. A study of significant disturbances indicates that protective relays are involved in one way or another in 75% of major disturbances. A common scenario is that the relay has an undetected (hidden) defect that was exposed due to the condition created by other disturbances. Given the importance of hidden failure modes in traditional relaying systems, intervention by computer-based rational control schemes is proposed. Relays with high-vulnerability indices can be identified, and their vulnerable functions and failure modes identified. Countermeasures to reduce or eliminate the likelihood of the hidden failure of key relays can be provided.
