Wide-Area Adaptive Protection Using Distributed Control and High-Speed Communications

New concepts of wide-area adaptive protection using distributed control and high-speed communications may reduce the likelihood of catastrophic failures in power systems. We suggest a communication and control structure designed to avoid and/or reduce the impact of misoperations of protection devices, for example, from hidden failures. We propose two different operating modes of the system, anticipative and responsive. We also indicate how such a system can respond to emergencies within the time available.
