APF/SVG module automatic calibration testing system and testing method

Abstract

The invention provides an APF / SVG module automatic calibration testing system and testing method. A host computer, after receiving an instruction to start the test, the host computer automatically downloads the program for an APF / SVG module to be tested through a program downloader, and acquires the testing data of the APF / SVG module to be tested through a comprehensive testing device; the comprehensive testing machine provides different AC power, DC power and testing signals to the APF / SVG module to be tested based on the different testing statuses according to the control instruction received from the host computer; and the program downloader receives the program data transmitted by the host computer via a data interface and transmits the program data to the APF / SVG module to be tested. The automatic calibration testing system is simple in operation, one only needs to connect the automatic calibration testing system to the APF / SVG module to be tested, singly clicks the start-test button after the production information is input to the host computer, the next testing and calibration is automatically completed by the automatic calibration testing system, so that the calibration and testing work hours can be greatly shortened, and errors or omissions can be prevented.

Description

technical field [0001] The present invention relates to the field of calibration testing, in particular to an automatic calibration and testing system of an active power filter (APF: Active PowerFilter) / static var generator (SVG: Static VAR Generator) module, which is applied to APF / SVG The module is automatically calibrated, self-diagnosed, and automatically tested during the production process, wherein, the symbols / representations or meanings, the present invention can be applied to. Background technique [0002] With the development of the economy and power system, the problem of power supply quality has become increasingly prominent, and reactive power, harmonics, unbalance and voltage fluctuation have become the main problems affecting the quality of power supply. The demand of power users for power quality control equipment is increasing day by day, and in power quality control equipment, active power filter (APF) and static var generator (SVG) are more and more widely...

AI Technical Summary

Problems solved by technology

In addition, for the problems of the tested products, we should try our best to find them in the early stage, so as not to expose the problems in the later stage, causing the expansion of faults, causing additional production losses and reducing production efficiency

And this requires that the early test should cover all the hardware circuits as much as possible, so the workload of the test is greatly increased. To ensure the test efficiency, it is obviously necessary to use automatic product debugging and testing.
