摘　　要：七台河电厂采用的伊林公司生产的DRS数字继电器系统,不仅克服了由分立元件和晶体管元件构成的保护反映速度慢、维护量大的主要缺陷,而且具有完备的人机对话功能。对某些特殊的保护进行了详细的阐述,同时对调试过程中发现的问题进行了分析并加以改正。The digital relay system, manufactured by ELIN Co. Ltd, used in Qitaihe Power plant at present, not only overcomes slow response to protection system consisting of discrete component and transistor element and vast maintain work, but also has perfect man -machine dialogue function. Some special protection function was discussed in details, meanwhile some problems occurred in commissioning were analyzed and corrected in the paper.
