摘要

提出了一种新的电力摆挡时电网保护方案。当系统恢复正常工作状态时，被阻塞的保护继电器将被释放。该保护方案基于对称元件。EMTP仿真结果表明，本文提出的方案完全适用于现代数字继电器。给出了不平衡故障的实例。

Fault identification during power swings with symmetrical component

This paper presents a novel power network protection scheme during power swing blocking. The blocked protective relays will be released when the system restores to its normal operating conditions. The protection scheme is based on symmetrical components. EMTP simulation results show the proposed scheme in this paper are quite suitable for modern digital-based protective relays. Examples are shown for unbalanced fault cases.
