摘要

传统的无通信的基于tcc的配电保护运行速度较慢，特别是对于距离电源较近的故障。此外，由于其TCC曲线的公差，可以放置在馈线上的保护装置的数量是有限的。这限制了发生故障时的分段能力。许多现代继电器和馈线保护装置都配备了通信功能。

Fast Communication-Based Protection and Isolation Schemes

Traditional TCC-based distribution protection without communications can be slow to operate, especially for faults closer to the source. Furthermore, the number of protective devices that can be placed on a feeder is limited because of the tolerance of their TCC curves. This limits the segmentation capabilities when a fault happens. Many modern relays and feeder protection devices are equipped with communication capabilities.
