Power transformer running state real-time monitoring method based on power consumption detection

The invention discloses a power transformer running state real-time monitoring method based on power consumption detection, and belongs to the technical field of power transformer safety running. The method of the invention is characterized by comprising a monitoring system and including a step 1001 of obtaining current and voltage signals of a power transformer; a step 1002 of obtaining input end active power and output end output power; a step 1003 of obtaining a normal power consumption value; a step 1004 of obtaining a power deviation percentage; a step 1005 of executing a step 1006 if being in a serious state, and executing a step 1007 otherwise; the step 1006 of sending out a tripping command; the step 1007 of executing a step 1009 if being in an abnormal state, and executing a step 1008 otherwise; the step 1008 of executing the step 1009 if running in a critical state, and executing a step 1010 otherwise; the step 1009 of sending out an alarm signal; and the step 1010 of continuing running.
