Abstract

The invention is applicable to the field of electric energy metrology, and provides a prepaid three-phase electric energy metering system and an electric energy control device. The metering system comprises an electric energy meter for settlement electricity consumption which is used for calculating the actual settlement electricity consumption of a user; and the electric energy control device, which is used for calculating the reference electricity consumption of the actual electricity consumption of the user, monitors the error of the electric energy meter for the settlement electricity consumption based on the reference electricity consumption in a real-time manner, and reports the out-of-tolerance alarm information to a control center when the error of the electric energy meter for the settlement electricity consumption exceeds a set value. The prepaid three-phase electric energy metering system adopts the electric energy control device with the function of calculating the reference electricity consumption to monitor the error of the electric energy meter for the settlement electricity consumption in a real- time manner, and reports the out-of-tolerance alarm information to the control center when the error exceeds the set value, which avoid a dispute about electric power charge caused by the out-of-tolerance error of the electric energy meter.

Description

technical field [0001] The invention belongs to the field of electric energy metering, in particular to a three-phase prepaid electric energy metering system and an electric energy control device. Background technique [0002] The prepaid electric energy metering device in the prior art mainly includes two kinds, one kind is the prepaid electric energy metering device that is made up of IC card prepayment controller and the electric energy meter of settlement electric quantity, and its shortcoming is: the use of this electric energy metering device and Some clauses in the Electric Power Law are in conflict; only the alarm can be called before the switch is turned on, and the switch-off information cannot be delivered to the user in advance; and the information of the device itself (such as: unpacking, out-of-tolerance information, etc.) cannot be actively reported to the control center , when the price of electricity changes, it is impossible to adjust the electricity in tim...
