Problems solved by technology
[0002] The process layer network is the core part of the entire smart substation network, but the monitoring of the flow information of the switch network has always been blank. Once a problem occurs in the network, it takes a long time to locate the problem and it is difficult to troubleshoot the problem, which brings a lot of trouble to the operators and maintenance personnel.

Embodiment Construction
[0025] In order to facilitate those of ordinary skill in the art to understand and implement the present invention, the present invention will be described in further detail below in conjunction with the examples. It should be understood that the implementation examples described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0026] Such as figure 1 As shown, a smart substation network traffic monitoring and early warning method includes the following steps:
[0027] Step 1. Analyze the SCD file of the smart substation and extract the IED device message parameter information. The above IED device message parameter information includes:
[0028] The SV sampling frequency value in the SV sending control block information of all IED devices;
[0029] The GOOSE transmission control block information of all IED devices, GOOSE transmission control block information includes: heartbeat message interval T0, f...

The invention discloses a process level network traffic monitoring early-warning method based on a smart switch. The method comprises the following steps: extracting message parameter information of IED equipment; extracting VLAN configuration data of a switch port; calculating a traffic volume theoretic value of the IED equipment; calculating a traffic volume theoretic value of the switch port; receiving a statistical message sent by the switch according to a statistical report control block, and recording the real-time value of input traffic volume at the switch port and the real-time valueof the output traffic volume at the switch port; and comparing the warning information and generating warning information. Through adoption of the process level network traffic monitoring early-warning method, the running condition of the whole process level network is monitored; the switch port at which the traffic exceeds a preset error range is warned; the potential safety hazard of the processlevel network is found in time; and stable running of a smart transformer substation network is facilitated.
Description
technical field [0001] The invention belongs to the field of intelligent substations, and in particular relates to a method for monitoring and early warning of process layer network traffic based on an intelligent switch. Background technique [0002] The process layer network is the core part of the entire smart substation network, but the monitoring of the flow information of the switch network has always been blank. Once a problem occurs in the network, it takes a long time to locate the problem and it is difficult to troubleshoot the problem, which brings a lot of trouble to the operators and maintenance personnel. [0003] With the application of new switches in smart substations, the monitoring information previously obtained through the SNMP protocol is now changed to model the switch and obtain switch information in real time through the MMS network, so that monitoring switch equipment is as convenient as monitoring protection equipment. [0004] The present inventio...
