Automatic detection system and detection method for digital tester

Abstract

The invention discloses an automatic detection system and method for a digital tester, the system includes a PC terminal installed with automatic detection system software, the PC terminal is connected to a switch through a network cable, and the digital tester and the detection device pass The network cable is connected to the switch; the standard clock source is connected to the detection device through an optical fiber cable for timing the detection device; the detection device is connected to the digital tester through an optical fiber cable to synchronize the time of the digital tester; the digital tester 9‑2 / GOOSE input and output The optical port is connected to the digital tester 9‑2 / GOOSE output and input optical port through an optical fiber cable; the hard contact input and output port of the digital tester is connected to the hard contact output and input port of the detection device through a cable. The system can realize the automatic detection of the digital tester, and improves the detection efficiency of the digital tester.

Description

technical field [0001] The invention relates to the technical field of automatic testing of intelligent substations, in particular to an automatic testing system and testing method for a digital testing instrument. Background technique [0002] With the development of smart substations, digital protection devices using IEC61850-9-2 messages and GOOSE messages have been widely used in smart substations, and digital testers are required for testing digital protection devices. At present, the detection standards of traditional analog testers have been relatively perfect, and the detection standards of digital testers have just been released in recent years. Most of the detection methods for digital testers are manually detected by inspectors, and digital network packet analyzers are required. Record the message output by the tester, and compare the actual voltage and current amplitude, phase, frequency and other data in the message by manual search, not only the operation effic...

At present, the detection standards of traditional analog testers have been relatively perfect, and the detection standards of digital testers have just been released in recent years. Most of the detection methods for digital testers are manually detected by inspectors, and digital network packet analyzers are required. Record the message output by the tester, and compare the actual voltage and current amplitude, phase, frequency and other data in the message by manual search, not only the operation efficiency is low, but also the entire detection process lacks uniform operation standards and specifications, and the test report It takes a long time to sort out, and there is also the risk of misrecording or omission
