Problems solved by technology

[0002] At present, the inspection and testing of protection devices in power systems are completely manual testing methods, which have the following shortcomings: it is impossible to ensure that the testing process is completely carried out in accordance with the inspection procedures and standards (or work instructions); human judgment is required to determine whether the test results are qualified; Recording while testing, the efficiency is low; the human error rate is high during the testing process, which can easily lead to the failure of the test, and even cause accidents in serious cases;

Embodiment Construction

[0013] The present invention will be further described below in conjunction with the embodiments. The relay protection device automatic test system includes five parts: a PW tester, a computer, a POWERTEST test software platform, an automatic test template, and a printer. Among them, the PW tester adopts the latest generation of DSP digital signal processing technology, 16-bit digital-to-analog conversion and 32-bit numerical calculation accuracy. DSP has high-speed computing capability. Using advanced DSP technology, the data points of the PW series tester’s weekly wave output can be increased to 600 points, which greatly improves and improves the transient response speed and amplitude-frequency characteristics of the tester, and makes the test device It has a very powerful real-time closed-loop function. The PW tester uses a parallel communication port (or USB port, network port) to connect to the computer to ensure that the serial port of the computer is free, so that the s...

Abstract

The invention relates to an automatic test system of a relay protection device, and the system comprises five parts: a PW tester, a computer, a POWERTEST test software platform, an automatic test template and a printer, wherein the PW tester employs the advanced DSP digit signal processing technology, 16-bit digital-analog conversion and 32-bit value calculating precision. Besides, the tester is connected with the computer through a parallel communication port (or a USB port, a network port). The POWERTEST test software platform, based on original PW series test software, employs a novel program structure, applies database and modular structure technologies, and employs the test template mode to customize a test program. The automatic test template is the practical test program operating on the POWERTEST test software platform. The automatic test system has high degree of standardization, effectively improving work standard and efficiency.

Description

technical field [0001] The invention relates to the technical field of electric equipment testing, in particular to an automatic testing system for a relay protection device. Background technique [0002] At present, the inspection and testing of protection devices in power systems are completely manual testing methods, which have the following shortcomings: it is impossible to ensure that the testing process is completely carried out in accordance with the inspection procedures and standards (or work instructions); human judgment is required to determine whether the test results are qualified; Recording while testing, the efficiency is low; the human error rate is high during the testing process, which can easily lead to the failure of the test, and even cause accidents in serious cases; Contents of the invention [0003] The present invention overcomes the deficiencies in the above technologies, and develops an automatic test system for relay protection devices with a hi...
