The Research And Application Of Remote Centralized Meter-reading System

The research and application of remote centralized meter-reading system is an important direction for future development of grid companies, which composes the main part the smart grid. Since the 1990s, the discovery and development of remote meter-reading system is always on its way. We are to further perfect system and application,now.The centralized meter-reading system mainly consists of power meter, energy terminal unit, communication network, main station. The system is designed to permit visual remote reading of metered energy usage, energy metering, and line loss analysis, excluding remote billing and connect/ dis-connect function that needs to be further furnished.Firstly, the paper introduces the components and general architecture of remote centralized meter-reading system, illustrates the components of the system.The paper mainly introduces the key parts of the system, devices of energy data terminal unit from six different producers and their application range, and different schemes of remote meter-reading.Secondly, the paper introduces the software design and development of remote centralized meter-reading system on information software platform. Introduceing two master station platform of software in detail,one is the previously developed of the terminal factory:COM3000 energy automatic metering-reading management system;another is a new development of the unified national technical standard for smart grid:customers' energy usage information collection system.In the end. the paper elaborates the characteristics of integrating development between The remote centralized meter-reading system and markrting system in the smart grid. Through the unified interface specifications and interface technology,realize to connection with the Marketing and management business applications. Receive the information of collection task,Control tasks,Assembly and Disassembly tasks.etc. Provide data support and back-office protection of marketing business for meter-reading management,Orderly power management, electricity collection, electricity inspection and so on. This system can also connect with other business applications, data sharing.
