Research on transformer protection configuration suitable for overseas power grid
本文对海外市场变压器保护配置方案进行研究,给出包括主保护、后备保护及非电量保护的完整配置方案;对海外电网变压器继电保护相关的差动曲线整定、零序反时限保护、中性点接地、非电量保护电流闭锁、IEC 61850 ed2.0 等进行研究并给出具体的解决方案.
This paper studies the transformer protection configuration schemes in overseas market,and gives a complete protection configuration scheme,including main protection,backup protection and non-power protection.It also studies some special problems of transformer relay protection in overseas grid,such as differential curve setting,zero-sequence inverse time-limit protection,neutral grounding,non-electric protection current locking,IEC 61850 ed2.0,and gives specific solutions.
