摘　　要：介绍采用电力系统全数字仿真装置对数字线路保护装置进行数字动模试验的电磁仿真模型和试验项目,分析试验中发现的产品重合闸时间脉冲展宽离散、接地距离II段未经零序电流闭锁等问题,提出数字线路保护装置在TA断线后再次发生故障时动作行为的优化建议。This paper introduces the line electromagnetism simulation model and test item of the digital dynamic test for main digital line protection equipment with ADPSS,analyzes some problems found from the detection, such as reclosing time discreteness,zone II of grounding protection failed to be blocked by zero-sequence electric current,puts forward some optimization suggestions of preforming characteristics during the period of TA break and a fault happens in a later time.
