The invention discloses a method for identifying electricity meters in a transformer area of an electrical power system, which belongs to the technical field of power line communication. The method comprises the following steps that: a coordination unit controls a voltage pulse transmitter to send a voltage pulse signal carrying a transformer area mark of a transformer area where the coordination unit is located to a subordinate power transmission network of the transformer area and queries identification marks separately acquired by each station unit from the voltage pulse signal in the power transmission network in a power line carrier communication manner; the transformer area mark of the transformer area is compared with the identification marks fed back by the station units so as to determine whether the station units are in the transformer area; and if the station units are in the transformer area, electricity meters corresponding to the station units are determined to be in the transformer area, and a
