The invention discloses a
GOOSE (Generic Object Oriented Substation Event) and SV (Sampled Value) broken link fault positioning method and
system based on a switch, a storage medium and equipment, and the method comprises the steps: firstly detecting the connection state of a switch forwarding
GOOSE and an SV message port, if the connection state is not abnormal, detecting the FCS
packet loss condition of the switch forwarding
GOOSE and the SV message port; if no FCS
packet loss abnormity exists, the forwarding
packet loss condition of a GOOSE and SV
message forwarding port of the switch is detected, if forwarding packet loss occurs in the port, whether switch networking, switch port flow and switch configuration are abnormal or not is further checked, and if no abnormity exists, the
correctness of the GOOSE and SV messages of the device is checked. According to the method, the GOOSE and SV broken link fault range can be quickly and efficiently positioned through rigorous judgment logic by utilizing the existing port state information, the port flow statistical information, the port
MAC address information and the GOOSE and SV message suppression configuration information of the switch, the
engineering field adaptability is high, and the method is suitable for large-scale popularization and application. And the efficiency and the accuracy of
troubleshooting GOOSE and SV broken link faults of the intelligent substation network by engineers are improved.
