Smart grid and energy system solutions include a broad portfolio of products, software and tools for grid infrastructure, utility metering, grid communication and smart home or building energy automation.
At the heart of any smart meter is the basic energy measurement function. It is critical that utilities and consumers can rely on the accuracy, security and reliability of this metering capability. Energy-measurement products from Texas Instruments are designed to meet all
of the requirements of ANSI C12.20 and IEC 62053 accuracy for Class 0.2 and Class 0.5 meters across the entire temperature range and with a full 2000:1 dynamic input range. Protecting meter integrity is a key to reducing non-technical losses in the field. TI’s electric meter metrology solutions include sophisticated anti-tampering protection.
Meter host processors must be able to support the multiple applications and external interfaces required in smart meters today. Meter data management applications such as DLMS/COSEM and communications stacks such as ZigBee® Smart Energy and Wireless MBus are all evolving to require larger amounts of memory and processor performance that TI delivers.
AMI networks require robust communications between the individual meters and the data concentrators which aggregate meter data in a neighborhood area before sending that information to the utility’s central office through a backhaul link. AMI networks are either RF (mesh or star topology) or power line communications (PLC). The choice between RF or PLC networks is usually driven by grid topology and geographical environment because these factors have enormous influence on network performance and infrastructure cost. TI’s solutions for AMI networks span both RF and PLC. These solutions also support most industry standards, including IEEE-802.15.4g, PRIME, G3, IEEE-P1901.2 and ITU-G.990x.
With leading innovations and expertise in metrology, power management, and wireless communication for the Smart Grid, TI works with customers to deliver compliant, cost-effective, and power-efficient solutions for gas, water, and heat meters.
