The invention relates to a substation electric quantity and electric energy quality integrated management system. The system comprises a plurality of electric energy meters with harmonic monitoring functions for performing electric quantity, voltage harmonic and current harmonic monitoring on three sides or two sides, all incoming lines and all outgoing lines of a main transformer of the substation; a plurality of voltage quality index monitoring devices installed corresponding to the main transformer of the substation and used for performing the voltage type index monitoring on the main transformer of the substation; a server respectively communicated with each electric energy meter and each voltage quality index monitoring device and used for accomplishing the acquisition and management of the electric energy data and the voltage quality data. Each electric energy meter and each voltage quality index monitoring device are connected with the server via an acquisition device and through an electric power local area network. The system disclosed by the invention improves the intensive management level of the substation, capable of reducing the equipment configuration of the substation, and lowering the construction investment of the substation.
