A method for remote diagnosis of abnormal equipment based on telemetry relates to a diagnosis method. At present, the real-time performance of power grid automation system and the eradication of hopping cannot be taken into consideration simultaneously. The invention comprises a telemetry invariance diagnosis, a telemetry overrun diagnosis, a main transformer bus power flow unbalance diagnosis anda transformer temperature rise abnormal diagnosis. The technical scheme solves the problem that the abnormal situation of the equipment can be detected without affecting the operation performance ofthe EMS by means of using an external plug-in system; deep patrol automatically identifies the data of power network operation at fixed period, searches out the problem information, and displays it through charts and graphs. Monitoring information analysts can analyze the current information obtained through the depth patrol, also can query the historical patrol information and form the same period, ring comparison results
