Design of Automatic Detection System for Relay Protection Tester Based on Lab VIEW
Aiming at the problems of existing relay protection testers such as complex testing procedures,low automation,and low efficiency of point-to-point debugging,an automatic testing system of relay protection tester based on LabVIEW is proposed.As main control chip,the system hardware of STM32F407ZGT6 is chosen to develop the output conversion device of the relay protection tester,and the automatic control tester and standard apparatus are connected into test circuit instead of manual disconnecting and wir-ing behavior.By taking LabVIEW as a development platform,the system software is developed including the modules of instrument communication,automatic detection,report generation,compulsory selection of measuring points,etc.,realizing the automatic detec-tion of the relay protection tester.By testing a type of relay protection tester,the results show that the system runs stably,it can re-alize one-click automatic detection,has a friendly user interface,can replace the complex manual detection method,and has a certain engineering application prospect.
