Multi-rate cost control system and electric energy meter

Abstract

The invention provides a multi-rate cost control system and an electric energy meter. The electric energy meter comprises a measuring body and a management module; the measuring body conducts time-sharing measurement on electric quantity on the basis of 15 minutes and stores the result in corresponding registers; the management module receives rate configuration parameters on the second day and stores the parameters, after measurement is conducted on the second day, charging is conducted according to the rate configuration parameters, and electric quantity information and charging results which are subjected to time-haring measurement by all the registers on the second day are sent to an electricity information collection system main station through a concentrator and a collector. The multi-rate cost control system divides different time periods of a whole day by taking 15 min as a node, and precise charging of different time periods of every day can be achieved. Accordingly, charginginformation of 360 days can be stored, by means of collection and storing of mass data of a measuring terminal, after the data is transmitted to a main station database, flexible rate configuration can be provided, and data tracing can be achieved. The electric energy meter is simple in structure, and by means of reasonable configuration of the registers, detailed recording of the cost informationcan be achieved.

Description

technical field [0001] The invention relates to a multi-rate tariff control system and an electric energy meter, belonging to the technical field of electric quantity information collection. Background technique [0002] With the transformation of the smart grid, the power industry implements the "full collection, full coverage, and full cost control" of the electricity consumption information system. By 2017, a round of smart grid transformation work will be basically completed, and the smart power consumption information collection system will be very mature. [0003] However, the cost control function of the metering terminal and the system still has the problems of difficult data traceability and inflexible rate setting. For example, in the process of user consumption, there are objections to charges, and because the problem persists for too long, it is impossible to analyze and resolve conflicts from the source. For another example, in order to achieve energy balance,...

[0003] However, the metering terminal and the fee control function of the system still have the problems of difficult data traceability and inflexible rate setting

For example, in the process of user consumption, there are objections to charges, and because the problem persists for too long, it is impossible to analyze and resolve conflicts from the source

For another example, in order to achieve energy balance, the power consumption operation unit needs to modify the rate in different seasons, even in a very special seasonal environment. For example, to adjust the energy consumption balance in the case of ultra-low temperature in winter or ultra-high temperature in summer, it needs to be adjusted in a very short special period Or readjust the rate in the case of random sending, which may increase the number of rates beyond the current rate, may increase to 6 rates, and of course may reduce to 1 rate
