隔离开关操作CVT引起二次电压异常的分析研究
摘要
利用电磁暂态仿真软件(EMTP)建立CVT及其所运行的变电站的等值电路模型
仿真计算一次隔离开关操作过程中CVT二次电压情况
并分析铜川330kV变电站CVT一次隔离开关操作过程中主变过励磁保护误动作的原因。
Abstract
This paper establishes equivalent models of CVT and the host substation by EMTP
and simulates secondary voltage during primary disconnect switching
then analyses the reasons for a malfunction of main transformer over-excitation protection in a 330kV substation in Tongchuan.
