On-line monitoring method and device for power utilization safety of power consumer

The invention discloses an online monitoring method and device for power utilization safety of power consumers. The method comprises the following steps: collecting historical power utilization data of all consumers; establishing an analysis model of historical data and a reference threshold value, and discriminating overload power consumption data; comparing and analyzing the maximum value of the overload data, matching the time corresponding to the value according to a time correlation function, and determining a platform data wide table display item; based on the overload data of the user, and in combination with the type, the importance level and the electric energy metering device classification, identifying the power utilization potential safety hazard level of the user; on the basis of the maximum value and time of overload, electricity utilization early warning data of the user on the day are generated to form electronic evidence; and the user potential safety hazard data and information are sent to a
