SEL Real-Time Automation Controller (RTAC)



SEL Real-Time Automation Controller (RTAC)

Automation Platform

The SEL RTAC is a powerful, multifunctional platform designed for the most demanding utility and industrial applications.

With precise, deterministic processing, integrated cybersecurity features, and rugged, industrial-grade hardware, the RTAC ensures reliable performance for critical operations, even in the harshest operating environments.

The RTAC platform offers a range of hardware options, extensive protocol support, and an embedded IEC 61131 logic engine for custom programming—making it a versatile solution for a variety of applications, ranging from data concentration and protocol conversion to comprehensive power management and control.

SCADA Remote Terminal Unit (RTU) and Substation Gateway

Quickly design an integrated substation RTU system that includes protocol conversion, SCADA communications, synchrophasors, time synchronization, data management, custom logic, and remote I/O.

Increase the number of I/O points with as many as 60 SEL-2240 Axion modules or six Axion nodes connected to one RTAC.

Communicate with any device through built-in client and server protocols that include DNP3. Modbus, IEC 60870-5-101/104. LG 8979. SEL Fast Messaging, Mirrored Bits communications, and IEEE C37.118 for synchrophasors.

Convert data between protocols, perform math and logic functions, and execute output logic for real-time control.

Event Report Collection

Collect event data automatically from connected devices through a wide range of supported protocols.

Automatically collect and archive events through the RTAC with the Device Management and Automation (DMA) application suite on SEL Blueframe.

By having all of the information from each intelligent electronic device (IED) processed through the RTAC, you get immediate notification of any issues through the alarms, Sequence of Events (SOE) logs, and/or email messages.

Versatile Control Solution

Deploy the RTAC as a specialized control solution for a range of common industry challenges using optional software extensions.

Turn the RTAC into a synchrophasor vector processor and detect the onset of wide-area oscillations with the Horizon SVP Plus extension. Control distributed energy resources (DERs) and optimize power flow at the point of common coupling with the Grid Connect extension.

Partner with SEL Engineering Services to develop custom solutions for complex problems requiring integration and power system studies.

Detect and de-energize broken overhead distribution lines within milliseconds with the falling conductor mitigation solution.

Ensure grid stability and an uninterrupted power supply with SEL powerMAX Power Management and Control System solutions for microgrids, industrial facilities, and wide-area power systems.

Human-Machine Interface (HMI)

Provide cost-effective local and remote monitoring, control, and annunciation for substations and other processes by installing the optional web-based HMI, available for most RTAC models and the Axion.

acSELerator Diagram Builder SEL-5035 Software includes features for one-line and annunciator panel design and indirect tagging and comes with an integrated SOE viewer for alarm notification.
