In order to meet the 21st century customer requirements for power quality, to allow access to various forms of power generation, to operate power markets and to optimize assets, countries around the world are moving towards smart grids. Smart grids are based on high-speed and bi-directional communication, advanced sensing and measurement technologies, control methods, and decision support systems to achieve reliability, security, economy, and efficiency to achieve information, digitalization, automation, and interaction.
Smart grid consists of Advanced Measurement System AMI, Advanced Distribution Operation ADO, Advanced Transmission Operation ATO, and Advanced Asset Management AAM. smart meters, as the most important component of Advanced Measurement System AMI, have higher requirements and greater responsibilities. Compared with traditional meters, smart meters have increased functional modules such as two-way communication with the grid, user information management, metering information management, and electricity consumption monitoring. The framework functions of smart meters are the same in all countries and regions, but the focus on specific functions will be different; some focus on anti-tamper, some focus on data timeliness, some focus on the integrity of historical records, etc., and the communication methods used vary according to the environment of each country. The appearance of smart meters used in national power bureaus are mainly wall mounted or ANSI standard round meters. The wall mounted or ANSI standard round meter is large in many places with limited installation space. For this point in the market, Yongtailong conventrate on the field of din rail meter over 20 years, developed a series of din rail mounted smart meter. This series of rail type smart meters combine the advantageous functions of China National Grid Meter, EU Smart Meter and Africa Smart Meter in terms of function, and meet the certification requirements of CPA and MID in terms of performance.
Din rail type smart meter function features.
1、Single-phase and three-phase din rail mounted smart meters with small size and easy installation.
2、Communication mode: RS485, 4G; communication protocol supports Modbus, DLT645 dual protocol
