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

The protective relaying device Auto-Test System

Technical field

The present invention relates to electric power equipment detection technique field, specifically is a kind of protective relaying device Auto-Test System.

Background technology

The protective device verification test of electric system at present is manual testing's mode completely, has the following disadvantages: can not guarantee that test process carries out by inspection procedure standard (or job instruction) fully; Test result whether artificially judge by qualified needs; In the test process, the record while testing, efficient is low; Artificial error rate height in the test process causes the failure tested easily, under the serious situation even cause accident;

Summary of the invention

The present invention overcomes the deficiency of above technical existence, has developed the higher protective relaying device Auto-Test System of a kind of automaticity.

Technical scheme of the present invention is: the protective relaying device Auto-Test System comprises PW tester, computing machine, POWERTEST test software platform, automatic test template, printer five parts composition.Wherein, the PW tester adopts latest generation DSP Digital Signal Processing and 16 digital-to-analog conversion and 32 numerical evaluation precision.DSP has arithmetic capability at a high speed, adopt advanced DSP technology, make PW series of tests instrument weekly the data point of ripple output bring up to 600 points, improve and improved the transient response speed and the amplitude versus frequency characte of tester greatly, and make proving installation have very powerful real-time closed-loop function.

The PW tester adopts parallel communication mouth (or USB mouth, network interface) to link to each other with computer, and the serial port free time of assurance computer, this serial port just can link to each other with the protective device of being tested like this.While operational testing instrument and tested protective device on a computing machine, particularly protective device manufacturing enterprise is very convenient in test process for this.Simultaneously, parallel port (or USB mouth, network interface) has higher transfer rate, can improve the response speed of proving installation, realizes the real-time control of tester and test fast.

The POWERTEST test software platform is on the basis of former PW series of tests software, adopts new program structure, and application data base and modular construction technology adopt the test template mode to customize test procedure; Automatically test template is the practical test procedure that runs under the POWERTEST test platform software environment; special-purpose relay protection test program at concrete model protective device exploitation; automatically test template software is to tested tissue flow process, normative testing method; non electrical quantity protection test event awards method of testing guidance and safety instruction and test result input interface; electric quantity protective awards wiring and other prompting and finishes test automatically, generates the complete test report that meets the norm standard form after test is finished automatically.

The PW tester has two and overlaps independently self-checking system.One cover is finished voltage source short circuit, current source open circuit, overheated and distorted signals detection by pure hardware.Another set ofly calculate by sampled value (supply voltage and the main frame temperature that comprise proving installation) being carried out discrete fourier (DFT), output valve is carried out mathematical analysis, realize supervision operating condition by software.Two cover systems are separate, for the undesired operating modes such as open circuit, short circuit, overload, externally fed electric voltage exception and tester main frame overtemperature of power supply signal, install and self have the excellent protection function.

When the present invention uses, at first the operational computations machine is opened POWERTEST test software platform master interface, select the path of automatic test template place file, open automatic test template, enter test interface then, the non electrical quantity test: program prompts test event, method of testing and technical requirement, accept the check result that artificial editor imports.Electric quantity test: manually import definite value, crucial test parameters is calculated automatically by definite value and is obtained; Before the electric quantity test, prompting test connection figure, pressing plate are thrown and are moved back, the safety event program, the start button F2 that clicks the POWERTEST test interface begins test, in the process of the test test findings is assessed automatically, click the report button of POWERTEST test interface at last, automatically generate the test report of standard format, and come out by printer prints.

Of the present invention have a suitable effect:

1, increase work efficiency, proving time shorten to have a power failure: according to the standardized work guiding book finish automatically test, automatically assess test result, generate the test report of standard format automatically, comprise the test findings of non electrical quantity;

2, improve inspection quality, reduce artificial error rate: in strict accordance with norm standard and job instruction carry out field test, the test process system points out tester's wiring and throwing to move back information such as pressing plate automatically.
