The invention discloses an automatic debugging system and debugging method for monitoring information. The automatic debugging system for monitoring information mainly comprises an EMS system, a substation module and an automatic debugging main system, wherein the automatic debugging main system is used for generating a debugging task so that the substation module sends warning information to theEMS system and the automatic debugging system, and the automatic debugging main system is used for comparing the warning information so as to complete debugging and generating a debugging report. Thedebugging method comprises the main steps of 1) building a debugging task, and issuing the debugging task to the substation module; 2) generating a driving signal by the substation module according tothe debugging task, and sending monitoring warning content to the EMS system and the automatic debugging main system by a driving master controller according to a monitoring information point table;and 3) comparing monitoring warning content recorded by the EMS system by the automatic debugging main system, performing difference analysis so as to evaluate a signal debugging condition between thesubstation and the EMS system and generate the debugging report. By the automatic debugging system, automatic debugging of substation monitoring information is achieved, and the efficiency is substantially improved.
