SEL Accelerates Automation System Design
IEC 61850 was created to be an internationally standardized method of communication and integration and to support systems built from multivendor intelligent electronic devices (IEDs) that are networked to perform protection, monitoring, automation, metering, and control. Combine IEC 61850 technology, Ethernet networking, and SEL high reliability to perform station computing and protection, automation, and control for distance, current differential, distribution, transformer, bus, motor, and bay control applications.
- Features and Benefits
- Streamline Configuration With acSELerator Architect® SEL-5032 Software
Easily configure and document IEC 61850 communications between devices from multiple suppliers.
- Easily Change Relay Message Configuration
Only SEL relays accept Configured IED Description (CID) files to change the configuration of the IEC 61850 messages, as called for by the standard. Devices from other suppliers use the CID files to document the messages, but require firmware changes or nonstandard settings methods to modify message configuration.
- Combine Multiple Ethernet Technologies
Merge appropriate new Ethernet technologies with existing, proven best engineering practices.
- Enhance Information Flow
Increase reliability with mission-critical IEDs, integrated within the bay and throughout the station via Ethernet networks.
- Decrease Maintenance Costs
Reduce initial cost and maintenance using highly reliable devices with sophisticated self-testing and diagnostics.
- Example Installations
La Venta II Substation in Mexico
Wind Park La Venta II is the world's first substation to show IEC 61850 in action within protective relays for a wide variety of vendors and to prove interoperability among these devices.
Thirty-Substation Modernization Project in Brazil
This project includes the complete modernization of 30 distribution substations belonging to Elektro Eletricidade e Serviços S.A., a large electric distribution utility in Brazil.
PPL Next-Generation Substations
Replacing hard-wired connections with digital communications over Ethernet networks requires new engineering and testing practices. PPL Electric Utilities Corporation designed, installed, and tested a new high-voltage substation using next-generation relay and control equipment. This next-generation substation is based on networked Ethernet IEDs communicating via IEC 61850.
RTU Replacement in the United States
An electric utility distribution group replaced pad-mounted switch remote terminal units with SEL-2411 Programmable Automation Controllers communicating via IEC 61850 links. They needed various I/O types and an easily scalable solution to support the different I/O requirements for each of three types of switches.
