Sources Sought SEL-3555

The Naval Facilities Engineering Systems Command, Pacific (NAVFAC Pacific) is conducting a market survey to identify potential sources of supply for a transformer protection relay with equal performance requirements as the SEL-3555, manufactured by Schweitzer Engineering Laboratories (SEL). The required product should have real-time automation controller capabilities, including substation automation, communications gateway, logic and control, data collection and monitoring, and cybersecurity and system integration. Interested parties should submit detailed technical data for evaluation. The key aspects of the job include: • Substation Automation: provide a real-time automation controller to coordinate protection, control, monitoring, and communications between intelligent electronic devices (IEDs), programmable logic controllers (PLCs), human-machine interfaces (HMIs), and supervisory control and data acquisition (SCADA) systems. • Communications Gateway: support protocol conversion and data concentration using industry-standard communications protocols, enabling interoperability between multi-vendor substation equipment and enterprise systems. • Logic and Control: provide programmable compliant logic for implementing substation control schemes, equipment interlocking, automation sequences, alarm processing, and custom control applications. • Data Collection and Monitoring: continuously collect, process, and archive operational data from connected devices, including relay status, metering, alarms, sequence of events, and equipment diagnostics. • Cybersecurity and System Integration: provide secure remote access, user authentication, role-based access control, encrypted communications, and centralized management capabilities to support integration with utility, industrial, and control systems while maintaining cybersecurity requirements.
