Learning system and method for IED equipment in intelligent substation

The invention discloses a learning system and method for IED equipment in an intelligent substation. The method comprises the steps that a network coprocessor performs message type identification on areceived message; and based on the message type identification result and a set processing rule, the network coprocessor extracts and manages the feature information of the IED equipment to completethe learning of the IED equipment in an intelligent substation. According to the method, the information of the IED equipment connected with a switch interface is learned in real time; errors caused by configuration and wiring can be quickly found and positioned; the debugging efficiency is improved; potential safety hazards are eliminated; and safe operation of a power system is guaranteed. 本发明公开了一种智能变电站中IED设备的学习系统及方法，所述方法包括网络协处理器对接收到的报文进行报文类型识别；基于报文类型识别结果及设定的处理规则，网络协处理器提取和管理IED设备的特征信息，完成智能变电站中IED设备学习。本发明实时学习交换机接口所连接的IED设备信息，能够快速查找定位出由于配置及接线导致的错误，提高调试的效率，消除安全隐患，保障电力系统安全运行。
