Grid Metering Processes Commercial process Billing System Energy values (kWh, kvarh) Grid Meter Network Management System Network values (U, I, P, Q) Operational process
Grid Metering Measurement Measurement quality exceeds Class 0.2S requirements. Measurement system 5 times faster as for industrial meters. Intergrated billing power quality for voltage dips and interruptions. Easy adaption for primary values. Scalable meter functionality.
Grid Metering Communication Modular communication separated from measurement. Standard protocol DLMS (IEC 62056-53). Open for other standard protocols for network management. Data traceability DLMS = Device Language Message Specification
Grid Metering Standards Secure data Commercial process TC13 IEC 61850 IEC 62056 (DLMS) Billing System IEC 870-5-102 proprietary protocols e.g. SCTM Grid Meter Concen-trator Network Management System IEC 61850 Operational process TC57 TC13
