摘要
文章从汽轮发电机失磁保护判据及各项整定计算入手,结合机组进相运行和失磁事故时的机端测量阻抗及低电压特征,提出了能很好地解决机组进相运行前和失磁事故后的验算方法,简单易行,方便运行和保护人员正确认识和分析,以便更好地满足机组安全运行的要求。
This article from loss of field protection criterion and the setting calculation of steam turbine generator, combined with the terminal impedance measurement and low voltage characteristics unit leading-phase operation and loss of field accident, put forward the simple and practicable calculation method, which can well solve the problem run before leading-phase operation and after the accident in the magnetic unit, convenient operation and protect personnel correct understanding and analysis, in order to better meet the requirement of unit operation.
