摘要

发电机差动保护是同步发电机最重要的电气保护之一。它的工作原理是基于各相绕组的输入电流和输出电流的比较，并允许在电流不相似时跳闸。在许多情况下，由于电流互感器(CTs)饱和，假差动电流会导致不必要的跳闸命令。本文提出的判据可以识别保护区内是外部故障还是内部故障，并可以防止由于ct饱和引起的跳闸命令。

Improvements to generator differential protection based on the criterion of signs of the DC-component

Generator differential protection is one of the most important electrical protections of synchronous generator. Its operation principle is based on the comparison of the input current and output current at each phase winding and it allows the trip when the currents are not similar. In many cases, a false differential current causes unwanted trip commands as a result of the saturation of current transformers (CTs). In this paper, the proposed criterion can identify whether it is an external fault or an internal fault in the protection zone and it allows preventing trip commands which have been caused by the saturation of the CTs.
