Three phase pre-payment electric energy metered system and electric energy control device

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, and in particular relates to a three-phase prepaid electric energy metering system and an electric energy control device. Background technique [0002] The prepaid electric energy metering devices in the prior art mainly include two types. One is a prepaid electric energy metering device composed of an IC card prepaid controller and an electric energy meter that settles electricity. Its disadvantages are: the use of the electric energy metering device and the Some provisions in the Electricity Law are in conflict; the alarm can only be called before the switch is opened, and the information of the switch cannot be sent 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 electricity price changes, the electricity cannot be adjusted in time. [0003] The other is a GPR...
