User ammeter data acquisition state abnormity identification method and system

The invention relates to the technical field of electric power data identification, and discloses a user ammeter data acquisition state abnormity identification method and system, and the method comprises the steps: screening out a user ammeter whose working state is an operation state, judging whether the corresponding user ammeter passes the acceptance check of a metering automation system, and if the acceptance check is passed, executing the step 1; if yes, acquiring load curve data of the user ammeter, if not, acquiring real-time load data of the user ammeter, judging whether the user ammeter is missing or not according to the real-time load data, and judging whether the missing number of the user ammeter is abnormal or not according to the type of the metering point; if yes, voltage class information and load voltage data of the user ammeter are obtained, whether the user ammeter loses voltage or not is judged according to the voltage class information and the load voltage data, and if it is judged that
