摘要
本文介绍ASEA公司生产的RAZFE型距离保护振荡闭锁的原理,分析了振荡闭锁回路接线的性能及特点,提出“圆套圆”特性的功率振荡元件应考虑的问题及对RAZFE型距离保护振荡闭锁的改进意见。
The principle of power swing blocking of ASEA's distancerelay type RAZFE is introduced in this paper. The performance andcharacteristics of the swing blocking circuit connection are also analysed.Problems concerning the setting of the power swing element characterizedwith 'two concentric circles' and the improvement of the relay aresuggested.
