APP RTAC: SEL Real-Time Automation Controller (RTAC)

APP RTAC is a highly interactive course that teaches you how to configure a substation communications scheme using the Real-Time Automation Controller (RTAC) model of the SEL-3350 computing platform.  

During this training, you will use a small equipment setup, including the SEL-3350 RTAC and the SEL-751 Feeder Protection Relay, to simulate a larger logical configuration. After learning core concepts from the instructors, you will receive real-world scenarios and work in groups of two to configure a communications scheme. The activities are followed up with discussion and review. 

Note: This class was previously called APP 3530.

Learning Outcomes

At the conclusion of this course, you will be able to:

• Use the RTAC web interface to configure settings, such as user accounts, and for troubleshooting purposes, such as reading status and alarm logs from the RTAC. 
• Use acSELerator RTAC to efficiently manage RTAC settings and to perform common operations, such as reading/sending settings and backing up/restoring them. 
• Configure DNP3, SEL, Modbus, and Mirrored Bits Communications protocol application settings. 
• Configure the RTAC to allow engineering access to connected IEDs. 
• Configure the RTAC to accept and provide time synchronization using a variety of methods, such as IRIG-B and Network Time Protocol (NTP). 
• Create user logic programs and functions with the IEC 61131-3 programming language in Continuous Function Chart, Structured Text, and Ladder Diagram languages. 
• Configure the RTAC to communicate to a DNP3-based SCADA system. 
• Configure the RTAC to communicate to a Modbus-based SCADA system using the Simple Tag Mapper extension. 
• Configure the RTAC HMI for status and control.

Student Background and Knowledge

Before you attend this class, we recommend that you:

• Have experience with acSELerator QuickSet SEL-5030 Software or complete the QuickSet section of CBT 101: Introduction to SEL Relays.
• Have an understanding of power system automation theory and application.
• Have experience with SEL relays.

Course Preparation

Before you attend this course, make sure your laptop has the following features and updated software:

• acSELerator QuickSet SEL-5030 (with all device drivers), acSELerator RTAC SEL-5033, and acSELerator Diagram Builder SEL-5035 Software.
• SEL-C662 USB driver and USB port.
• Google Chrome browser, Wireshark, and Ethernet port.

To operate correctly, acSELerator RTAC requires the specific network TCP ports listed below to be open. You can enable the ports by either turning off or adding exceptions to the firewall and antivirus software on your computer. Please work with your IT department to ensure they are open before attending this course.

• 5432 (TCP incoming): acSELerator RTAC project download/retrieval
• 1217 (TCP incoming): acSELerator RTAC online status monitoring and point forcing
• 5433 (TCP incoming): RTAC firmware upgrades
• 15453 (TCP incoming): Communications traffic monitoring for diagnostics/testing
• 443 (TCP incoming): HTTPS (RTAC web server)
• 80 (TCP incoming): HTTP (RTAC web server)

Please ensure that your laptop does not have any installation blocks before you come to class.
