Abstract

Disclosed is an automatic testing system for a converter. The automatic testing system for the converter is provided with a power supply module used for supplying power to a to-be-tested device, a testing control module, and a data collection module. The testing control module is connected with the power supply module, and the output end of the data collection module is connected with the input end of the testing control module. The testing control module sets and controls the output parameters of the power supply module according to the testing type of the to-be-tested device; the power supply module sends a regulated and corresponding power supply parameter to the to-be-tested device and provides power supply for the to-be-tested device; the data collection module collects parameters ofthe AC end and the DC end of the to-be-tested device and generates a report; and the data collection module sends the collected parameter information of the AC end and the DC end of the to-be-tested device to the testing control module. According to the automatic testing system for the converter and the usage thereof, different testing requirements can be adapted when in use; meanwhile, the tedious workflow of manual operation such as recording is avoided; the test is more concise; the labor cost is reduced; and the working error is reduced.

Description

technical field [0001] The invention relates to the technical field of power system testing, in particular to an automatic testing system for a converter. Background technique [0002] When testing the efficiency harmonics of energy storage converters and photovoltaic inverters (hereinafter referred to as the equipment under test), it is necessary to separately control the AC source, DC source, and power analyzer. Manually adjust the power of the DC source to make the device under test reach the specified power, then control the power analysis to store the data, wait for the storage to be completed, export the data and manually perform secondary processing and analysis of the data. This process is very cumbersome and wastes manpower time, and the data processing in the process of sorting out data is cumbersome and time-consuming. [0003] Therefore, aiming at the deficiencies of the prior art, it is necessary to provide an automatic test system for converters to overcome th...
