Embodiment Construction

[0028] Such as figure 1 As shown, all the meters in a substation are connected to the same data acquisition system through RS485 communication

[0029] On the terminal, the aforementioned data collection terminal can be one or more, and different types of data collection terminals can be connected to different numbers of ammeters. A general data collection terminal can be connected to 32 ammeters, so the number of data collection terminals can be based on Configure specific needs and situations. The other end of the data acquisition terminal is connected to the communication front-end processor through a network cable (or optical fiber or wireless GPRS, CDMA), and the communication front-end processor is connected to the data server through the TCP / IP protocol. The data collected by the data collection terminal is sent to the data server through the communication front-end processor and stored in the database.

[0030] The network server is connected to the data server throu...

Abstract

A metering and charging system of electric energy consists of four parts of data collection, data management, network browse and electronic report. It is featured as using data collection unit and data management unit to form databank for application, using network browse unit to browse data in databank and using electronic report unit to print out required data. The system has unified data platform being able to obtain remote electric energy data and it can ensure uniqueness, completeness and correctness of the data.

Description

technical field [0001] The invention relates to a system for measuring and monitoring various physical quantities of terminal equipment in an electric power system, specifically an electric energy metering and billing system, which belongs to the electric power industry automation control category. Background technique [0002] The electric power industry is an important pillar industry of the national economy, and electric power, as a special commodity, plays a pivotal role in the market economy. With the implementation of the Electric Power Law and the system reform of the electric power industry, the operation and management of the power grid is gradually moving towards commercialization. The construction of the electric energy metering system began with the development of electric power commercial operation and the emergence of diversified investment subjects in power plants. The main task of the electric energy metering system is to collect,...
