Problems solved by technology

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

Abstract

The invention discloses an automatic detection system and method for a digital tester, and the system comprises a PC end which is provided with automatic detection system software, the PC end is connected with a switch through a network cable, and the digital tester and a detection device are respectively connected to the switch through network cables. A standard clock source is connected with a detection device through an optical fiber cable and is used for timing the detection device; the detection device is connected to the digital tester through an optical fiber cable to perform time synchronization on the digital tester; the digital tester 9-2 / GOOSE input / output optical port is connected to a digital tester 9-2 / GOOSE output / input optical port through an optical fiber cable; and a hardcontact input / output port of the digital tester is connected to a hard contact output / input port of the detection device through a cable. According to the system, automatic detection of the digital tester can be realized, and the detection efficiency of the digital tester is improved.

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...
