The invention belongs to the technical field of electric energy metering and calculation, and particularly relates to a special computer for electric energy metering. The special computer for electric energy metering is characterized in that the special computer consists of a hardware system and a software system, the hardware system consists of six parts, i.e. an automatic calculation part, a keyboard input part, an input quantity and calculation result output and display circuit, a program memory, a calculation intermediate result memory and a clock circuit, and the software system also consists of six parts, i.e. monitoring software, keyboard scanning and processing software, display management software, arithmetical operation software, incorrect wiring type judgment software and correction coefficient solving and processing software. The special computer for electric energy metering has the advantages that the functions of incorrect electric energy correction coefficient solution, incorrect electric energy return and compensation calculation and the like are realized, the working capability of electric energy metering personnel, electricity use inspection personnel, meter reading personnel and other marketing personnel is improved, the electric energy return and compensation operation is standardized, and the economic losses of power supply enterprises and the contradictions between power supply and use parties are reduced.
