Intelligent terminal goose port independence detection system and method

Abstract

The embodiment of the present invention discloses a system and method for detecting the independence of GOOSE ports of an intelligent terminal, which are used to detect the independence of GOOSE ports of an intelligent terminal under test. The detection system includes: a digital relay protection tester, a A network performance tester and a message capture device; wherein, the network performance tester sends invalid background data to the first GOOSE port of the tested smart terminal, and the digital relay protection tester sends the second GOOSE port of the tested smart terminal Valid GOOSE data and control commands, test the execution time of control commands, and determine the impact of invalid background data of the first GOOSE port on the performance of the second GOOSE port; the network performance tester sends valid background data to the first GOOSE port of the smart terminal under test , restart the intelligent terminal under test, and determine the independence between the first GOOSE port and the second GOOSE port according to whether the message grabbing device grabs the valid background data during the restarting 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...

Problems solved by technology

[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
