比例制动和增量比例制动差动继电器的性能比较

Performance comparison of differential relays with rate restraint and fault component rate restraint

比例制动差动继电器和增量比例制动差动继电器在电力系统母线保护中都得到了应用 ,这两种继电器既有共同点 ,又存在一些差别。本文就这两种差动继电器原理和特点加以分析和比较 。

Both rate restraint differential relay and fault compoment rate restraint differential relay are used for bus protection in power system. They have many features in common, but there are also some differences betwween them. The principles and features of these two differential relays are analyzed and compared in this paper.
