Transformer substation link diagnosis device and method based on three-layer signal analysis

The invention relates to a transformer substation link diagnosis device and method based on three-layer signal analysis. The device comprises an automatic acceptance unit, and an SCD and RCD file analysis unit, a point table acquisition unit, a message signal capture unit, a point number selection unit and an automatic acceptance unit which are connected with the automatic acceptance unit. According to the method, the workload of fault point positioning in joint debugging acceptance is greatly reduced, the acceptance speed is increased, the acceptance report is generated according to the actual situation, the problem that the time consumption from problem discovery to defect elimination is too long in the previous acceptance process is fundamentally solved, and the acceptance requirementsof modern intelligent substations can be met. 本发明涉及一种基于三层信号分析的变电站链路诊断装置和方法，该装置包括自动验收单元，以及与自动验收单元连接的SCD与RCD文件解析单元、点表获取单元、报文信号抓取单元、点号选择单元和自动验收单元。本发明极大地减小了在联调验收中定位故障点的工作量，提高验收速度，并根据实际情况生成验收报告，从根本上解决了以往验收过程中从发现问题到消缺耗时过长的问题，能够满足现代
