变压器间及其与电流互感器暂态交互作用分析和保护对策

Analysis of Transient Interaction between Transformer and Current Transformer and Protection Countermeasures

变压器间与电流互感器之间的暂态交互作用对配电系统故障的判别存在较大的难度,如由于暂态交互作用而造成的故障判断时间较长等,造成安全问题的发生,影响其运行。基于此,结合实际情况,从变压器间及其与电流互感器暂态交互作用出发,对其相关问题进行了讨论,并提出了保护对策,其目的在于优化配电网络管理及提供供电安全性能。

The transient interaction between transformer and current transformer is difficult to distinguish the fault of distribution system,for example,the fault judgment time caused by transient interaction is longer,which results in the occurrence of security problems.Affect its operation.Based on the actual situation,from the point of view of the transient interaction between transformers and current transformers,the related problems are discussed,and the protection countermeasures are put forward,which aims at optimizing the management of distribution network and providing power supply security performance.
