Automation and Integration
SEL information processors enable you to design and implement both simple and complex intelligent electronic device (IED) integration solutions. Supported peer-to-peer technologies include SEL’s patented Mirrored Bits® communications and IEC 61850.
Real-Time Automation Controller
The RTAC can act as a data concentrator by using protocols such as IEC 61850 MMS client, Modbus®, DNP3, IEC 61850 GOOSE or MIRRORED BITS® communications to integrate both serial and Ethernet IEDs. Enable logging on any system or IED tag to view and archive a station-wide event record.
The RTAC Ethernet connection provides a means to remotely access the system to monitor logs and diagnostics. First establish a remote connection with any IED connected to the RTAC through Engineering Access communications channels. Then use the ACSELERATOR QuickSet® SEL-5030 Software suite to manage protection and control settings for these relays remotely.
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.
SEL Mirrored Bits Communications
SEL developed Mirrored Bits communications to provide high-speed, secure, point-to-point communication of real or virtual contact-status bits. Protection applications include directional element-based bus protection and replacement of tone-channel equipment for communications-assisted blocking, unblocking, permissive, and transfer trip schemes. Automation applications include high-speed sectionalizing, restoration and interlock schemes, and replacement of large bundles of field wiring with several small optical fibers, lowering costs and improving reliability.
- 55 times faster than other RTACs, providing powerful computing for large-scale automation projects.
- Increases cybersecurity by using exe-GUARD™ whitelist antivirus technology to allow only authorized applications to run.
- 1 ms deterministic processing intervals for time-sensitive protection and automation control.
- Eliminates the need for a PC in the substation due to an integrated video port and easy-to-use HMI.
