With the continuous innovation of intelligent reactive power compensation module and an increasing variety of its products,its processes of debugging and testing are also constantly cumbersome.It is almost impossible to complete large-scale production by hand.In order to solve those problems,this paper designs the automatic debugging and detection system of intelligent reactive power compensation module,using Cortex-M3 single chip microcomputer and power acquisition chip to realize the debugging and detection of different types of modules through the switch of relay,so that it can automatically realize the high-precision calibration of modules and the full-featured detection process.The whole system uses self-designed console,large screen LCD,matrix keyboard,modular interface,highly reliable self-protection measures,automatic data recording,which improves the production efficiency,ensures the safety of production,saves a lot of labor costs.
