[0005] However, the existing detection method has the following defects: if the two ports are not independent of each other, there can be data interaction, then after the data enters the GOOSE port, the flow direction of the data can be controlled by the program, so that the data entering the port does not Re-entering other ports may cause the smart device under test to control the data through the program to achieve the illusion of port independence

[0030] The detection of the independence of the GOOSE port in the present invention is carried out in two parts. The first part is the detection of the impact of a large amount of invalid background data in other GOOSE ports on the performance of the tested GOOSE port, and the second part is the detection of whether the tested GOOSE port captures valid background data in other GOOSE ports.
[0031] 1. Detect the impact of a large amount of invalid background data in other GOOSE ports on the performance of the tested GOOSE port
[0032] (1) Build a test platform, as attached figure 1 .
[0033] (2) Set the MAC=0x010CCD010001, APPID=0x0001 of the GOOSE1 subscribed by the smart terminal under test; use the network performance tester to send a large number of invalid background messages to the first GOOSE port of the smart terminal under test, and set the MAC of the background GOOSE2 =0x010CCD0100FF, APPID=0x00FF. According to the performance of different devices, it generally ...

The invention discloses an intelligent terminal GOOSE port independence detection system and a method which are used for detecting independence of GOOSE ports of a detected intelligent terminal. The detection system comprises a digital relay protection tester, a network performance tester and message grabbing equipment, wherein ineffective background data is sent by the network performance tester to a first GOOSE port of the detected intelligent terminal, effective GOOSE data and a control command are sent by the digital relay protection tester to a second GOOSE port of the detected intelligent terminal, execution time of the control command is tested, influence of the ineffective background data of the first GOOSE port on the second GOOSE port is determined, effective background data is sent by the network performance tester to the first GOOSE port of the detected intelligent terminal, the detected intelligent terminal restarts, and independence between the first GOOSE port and the second GOOSE port is determined according to whether the message grabbing equipment grabs the effective background data in the restart process.
Description
technical field [0001] The present invention relates to the technical field of power system substation automation, in particular to the detection field of smart terminals in smart substations, specifically a system and method for detecting the independence of the GOOSE port of a smart terminal device for judging the status of the device under test Whether the GOOSE port independence meets the standard requirements. Background technique [0002] As a new type of IED equipment in substations, smart terminals are suitable for various primary switch bays or transformer bays in smart substations. Its two main functions are: 1) Receive the control command of the process layer network or the direct control command of the relay protection device, and drive the corresponding exit circuit to complete the control function of the primary equipment; 2) Collect the position signal of the primary equipment , Alarm signals and other real-time data are published to the process layer network...
