摘　　要：对微机型发变组保护在定值设置方面存在的较多问题进行了原因分析,说明引起保护误动的原因通常并不是定值的数值整定出现错误。提出在定值整定时,不仅要设置保护数值,还要设置TA(TV)参数、变压器参数和保护元件的运算方式等非传统定值量。According to the problems of microprocessor-based protection settings for generator-transformer unit,it is explained that the causes of protection mal-operation is not always the wrong fixed-value setting.Not only the protection value but also TA,TV data,transformers data,algorithm of protection devices should be set during value setting,which are the non-traditional settings.
