摘要
通过对一起主变差动保护误动原因的分析,介绍了HN-2042型数字式变压器差动保护电流相位校正和幅值平衡补偿的基本原理,对误动原因进行了定性分析和定量计算,从技术和管理方面提出了防范措施。
According to the analysis of reasons of misoperation of differential protection, the basic principles of HN-2042 digital differential protection for transformer current phase correction and balance makeup of amplitude were introduced. Reasons of misoperation was analysed and calculated. The countermeasures were put forward from technology and management.
