摘　　要：结合以往综自化变电站经验,针对智能化变电站差动保护、线路保护、测量、计量二次电流回路在安装、调试过程中出现的极性接反、变比错误、光纤连接错误、内部虚端子关联错误问题,利用变压器短路阻抗进行通流试验,查找出存在问题并进行消缺,确保了设备稳定运行。Combined with previous experience in integrated automation substation,for intelligent subsataion's differential protection,line protection,measuring,measured secondary current loop in installation,commissioning process occurred polarity revesal,ratio error,fiber connection error,internal virtual terminal saaociated error problems,and it found out the existing problems using the transformer short-circuit impedance to flow test,to ensure the equipment's stable operation.
