调压不当导致主变压器后备保护动作分析

Analysis of Main Transformer Backup Protection Caused by Improper Implementation of Voltage Regulation Measures

    摘要
  • 摘要: 针对一起调压措施执行不当导致的主变后备保护动作案例,梳理主变分接头档位调节过程,剖析档位调节后主变后备保护误动机理,分析了事故原因,并通过PSCAD对分析结果进行了仿真验证。

     

    Abstract: In view of a case of backup protection of main transformer caused by improper implementation of voltage regulation measures, this paper combs the process of the shift adjustment of main transformer joint, analyzes the mechanism of the backup protection maloperation of main transformer after the shift adjustment, and analyzes the fault causes. At last the results are verified by simulation with PSCAD.
