| 摘 要： | 实现变压器纵差保护,首要解决的技术问题就是在正常工况下,使差动保护各侧电流的相位相同或反相,使由变压器各侧电流互感器二次流入差动保护的电流产生的效果相同。通过对国电南自变压器保护装置PST-1202和南京南瑞变压器保护装置RCS-978采用的相位补偿方法进行了详细分析比较,对两种补偿方法有了更清晰的认识。

| Abstract: | To implement transformer differential protection, first it needs to solve the technical problem in normal condition, that each side current differential protection should be the same or reversed so that the transformer from each side into the secondary differential current transformer to protection are the same. The phase compensations of protection device PST-1202 of Nanzi and protection devices RCS-978 of Nari are compared in detail.The two methods of compensation can be understood clear. |
