使用频率变化率（ROCOF）来检测配电网络中的不希望的孤岛已经在欧洲的一些国家完成，并且在其他一些国家被认为是可能的。已知ROCOF可改善孤岛检测;然而，从理论观点来看，使用它的好处并不很好理解，并且今天仍然难以量化其实际效果。针对逆变器为孤岛供电的常见情况，通过仿真研究了ROCOF对反孤岛保护非检测区的影响，分析了ROCOF的优点。
Using the rate of change of frequency (ROCOF) to detect undesired islanding in distribution networks is already done in a few countries of Europe and is considered a possibility in some others. The ROCOF is known to improve islanding detection; however, the benefit of using it is not well understood from the theoretical viewpoint and it remains difficult today to quantify its practical effect. The authors focus on the frequent situation where potential islands are powered by inverters, then, based on simulations, this study investigates the benefit of using the ROCOF by studying its effect on the non-detection zone of the anti-islanding protection.
