EN 61334-4-61:1998

Overview

EN 61334-4-61:1998 is a crucial European standard published by CLC that addresses distribution automation using distribution line carrier (DLC) systems. Specifically, this document focuses on the data communication protocols at the network layer, detailing the requirements for a connectionless protocol. The scope encompasses services required by the Data Communication Protocol (DCP) network layer sublayer entity, operating at logical interfaces with both the network user layer and the Logical Link Control (LLC) sublayer. This standard plays an essential role in ensuring reliable, efficient, and interoperable communication across power distribution networks employing carrier systems.

Key Topics

• Distribution Line Carrier Systems: EN 61334-4-61:1998 pertains to automation solutions implemented over existing power distribution lines, utilizing carrier signals for data transmission.
• Network Layer Protocols: The standard specifies the functions and services of the network layer within the DCP, essential for routing and handling of data packets in distribution automation networks.
• Connectionless Protocol: Emphasis is given to connectionless communication, where information is transmitted without the establishment of a dedicated connection, supporting efficient and flexible data exchange.
• Logical Interfaces: Defines the interactions between the network layer, the upper user layer, and the LLC sublayer, promoting modular and scalable network architectures.
• Service Requirements: Covers the requirements for service provision to users and lower protocol layers, aiding implementation and integration efforts.

Applications

EN 61334-4-61:1998 is practically valuable for organizations involved in:

• Power Distribution Automation: Ensuring seamless two-way communication within smart grids and automated substations, enhancing control and monitoring capabilities.
• Telecontrol and Telemetry: Supporting real-time and automated data flows for systems where remote measurement, monitoring, and control of utility networks is required.
• Smart Grid Deployment: Facilitating integration of advanced distribution management technologies, such as demand response, fault location, and distributed energy resource management.
