Network Security Device—Make the SEL-3530 or the SEL-3530-4 Real-Time Automation Controller (RTAC) the secure access point into your substation or plant. Implement Lightweight Directory Access Protocol (LDAP) central authentication and role-based user authentication, project passwords, web upload features, access logs, and secure engineering access via Secure Shell (SSH). Map security tags into SCADA reports for industry-leading integration of security technologies.

SCADA Remote Terminal Unit (RTU)—Quickly design an integrated substation RTU system that includes protocol conversion, SCADA communications, synchrophasors, time synchronization, data management, and custom logic.

Data Concentration—Communicate with any device through built-in client and server protocols. Exchange data through DNP3, Modbus, IEC 60870-5-101/104, LG 8979, SES-92, 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.

Substation Controller—Create your logic solutions in the embedded IEC 61131 logic engine, which comes standard with every RTAC. Build custom user logic. Access all system tags, including diagnostics, contact I/O, protocol data, and communications statistics, to provide unparalleled control flexibility.

IEC 61850 Integration—Integrate modern intelligent electronic devices (IEDs) into control and automation schemes with IEC 61850 GOOSE and the manufacturing message specification (MMS) client and server.

Operation Supporter/Regulator—Meet or exceed IEEE 1613 and protective relay specifications for harsh environments. The RTAC is designed to withstand vibration, electrical surges, fast transients, and extreme temperatures.

Event Collection—Detect, filter, and collect event data automatically from connected SEL relays. Fault location, fault current, and other data are populated into tags for easy retrieval through SCADA protocols. Automatically collect and archive events through the RTAC with acSELerator Team SEL-5045 Software.

Integrate Power Management With Industrial Control—Provide a powerful gateway between the substation and the factory using EtherNet/IP. This popular industrial protocol facilitates reliable communication between electronic devices in industrial automation systems. Use the RTAC EtherNet/IP adapter to exchange critical data for real-time monitoring, process control, and power system integration.

Substation 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 the RTAC and SEL-2240 Axion. acSELerator Diagram Builder SEL-5035 Software easily maps the RTAC tag database to reduce screen development time.

Updates

New RTAC Libraries

  • Fault Location: Calculate the impedance-based fault location for Axion SEL-2245-42 COMTRADE files to accurately locate the distance to faults on electric lines and extend the functionality of your digital fault recorder with the FaultLocation Library.
  • Condition Monitoring: Configure the ConditionMonitoring library to assess CT/PT health and extract specialized asset health reports from connected IEDs. This library is used for condition-based monitoring of power system assets that can assist in NERC PRC-005 compliance.
  • Grid Connect: The new release of the Grid Connect inverter-based control solution allows for a 5 MW system limit at an economic price point that includes support for loads behind meters, solar smoothing, peak shaving, time-shifted generation, and automatic charging of storage assets. 
  • Combine the EmailPlus library with the Report Generator library to generate professionally formatted reports that incorporate real-time tag data, and email those reports by integrating with secure mail systems. The EmailPlus library enables the RTAC to use mail servers that require a username and password.
  • Configure the FTPSync library to specify content to be monitored and synced automatically with a File Transfer Protocol (FTP) server. This library monitors specified folders and IEDs to detect when files are added or modified and sends those files to the FTP server.

  • Update tag and device names using the new refactoring feature. The changes will reflect through the entire acSELerator RTAC project, including the Tag Processor.

Firmware R142

Compare two RTAC configurations in acSELerator RTAC SEL-5033 Software to detect setting differences.

Firmware R141

  • Create custom user roles with relevant granular permissions to restrict access to need-to-know information.
  • Easily download a complete password report for IED communications protocol passwords to get access to connected relays in emergencies.
  • Provide indefinite access to the RTAC HMI by using the new infinite timeout option.

Firmware R140

Combine multiple oscillography event files generated by Axion modules into one substation event report.

Firmware R139

  • Easily access user-generated files, dynamic disturbance recorder records, collected oscillography files, and more using the RTAC’s S/FTP server.
  • Generate COMTRADE or CSV files with data from the RTAC’s logic engine, which can include synchrophasor, protection, or SCADA data.
  • Manage in-service RTACs through the web interface with Live Data viewing and forcing, firmware upgrades, project uploads, and communications capture collections.
  • Easily configure engineering access with the SEL Protocol Server and support for YMODEM file transfer, the acSELerator QuickSet SEL-5030 Software HMI, and enhanced access commands.
