本文演示了使用扩展等面积准则（EEAC），以确定是否孤岛电力系统保持暂态稳定后，网络已分裂。受控系统孤岛已被提出作为避免系统范围停电的最后手段。这种方法通常基于一些最小割集和/或最小功率干扰准则，但没有特别考虑暂态稳定性。通过开发先验暂态稳定性指标，可以使任何分裂方法更鲁棒，因为所提出的岛将满足静态（负载、发电平衡）以及暂态约束。如果所提出的割集导致瞬时不稳定的孤岛，则可以将其反馈到分裂方法，并提出新的割集和孤岛配置。
This paper demonstrates the use of the Extended Equal Area Criterion (EEAC) to determine if islanded power systems remain transiently stable after the network has been split. Controlled system islanding has been proposed as a method of last resort to avoid a system-wide blackout. Such methods are usually based on some minimum cutset and/or minimum power disturbance criterion but do not specifically take transient stability into account. By developing an a priori transient stability indicator, any splitting methodology can be made more robust as the proposed islands will satisfy static (load, generation balance) as well as transient constraints. If the proposed cutsets result in islands that are transiently unstable, this can be fed back to the splitting methodology and a new cutset and islanding configuration proposed.
