Example Embodiment
[0021] The present invention will be further described below in conjunction with embodiments.
[0022] Such as figure 1 As shown, a method for fault diagnosis of a physical link at the process layer of an intelligent substation includes the following steps:
[0023] S1. Analyze the SCD file to obtain the starting point and end point information of the logical link of the process layer of the whole station, mainly including the sending device, sending port, receiving device, receiving port and other information; obtain the whole station process layer switch configuration information from the SCD file, the switch The configuration information mainly includes the name of the switch, the number of each port, and the equipment connected to each port and the corresponding port; information such as soft pressure plate and broken link signal related to the logical link of the process layer is obtained. The switch configuration information parsed from the SCD file is separately stored in a...
