Modern countermeasurus to blackouts

摘要

A brief overview of modern transmission technologies and how they may be effectively used to enhance system dynamic performance in response to major system disturbances is presented. In this way, some of the risks of potential cascading outages and islanding of the system can be mitigated. The application of these devices requires proper coordination and tuning of controls to ensure robust performance. The key benefit is the ability to effect fast and automatic response to system disturbances, thereby enhancing damping in power oscillations, transient stability margins, and smooth voltage recovery and regulation following major system disturbances
