Intelligent electric meter terminal suitable for multiple users and power utilization management method

Abstract

The invention discloses an intelligent electric meter terminal suitable for multiple users and a power utilization management method. The terminal includes a wiring bus, an incoming line and a plurality of outgoing lines, wherein each outgoing line corresponds to a user; the incoming line is connected to the wiring bus through an electric energy general metering module, and each outgoing line is connected to the wiring bus through a subswitch, an electric energy sub metering module and a voltage and current instantaneous value sub sampling module in sequence; the electric energy general metering module and the electric energy sub metering module are connected with a reader-writer; and the reader-writer is used for information on electric cards.

Description

technical field [0001] The invention relates to the field of smart meters, in particular to a smart meter terminal suitable for multiple users and a method for managing electricity consumption. Background technique [0002] A smart meter is an intelligent terminal of a smart grid. It is no longer an electric energy meter in the traditional sense. In addition to the basic electricity consumption measurement function of a traditional electric energy meter, a smart electric meter is designed to meet the development needs of the smart grid and connect a large number of distributed clean energy generation It should also have accurate two-way multi-rate metering function, user-side control function, two-way data communication function of multiple data transmission modes, support for multi-user and multi-scenario use, support for electricity price curve release and time-of-use electricity price Intelligent functions such as billing, real-time collection and transmission of voltage ...

AI Technical Summary

Problems solved by technology

With the increase of user types and the diversification of application scenarios, the metering, billing, management and control functions of existing electric meters cannot meet the requirements, and solutions that meet the needs of multiple users and multiple scenarios must be proposed;

[0005] (2) It does not have perfect real-time acquisition and upload functions of voltage and current instantaneous values

At present, electric meters generally only collect information such as electric energy (including active electric energy and reactive electric energy), voltage frequency, etc., and do not have the real-time uninterrupted sampling function of instantaneous values ​​of voltage and current.
