Substation Automation Projects: Utility Real-Time Automation Controller

substation Schweitzer Engineering Laboratories SEL

Utility supplies: Schweitzer Engineering Laboratories (SEL) has released the SEL-3555 Real-Time Automation Controller (RTAC). It provides an Intel Core i7 2.5 GHz dual-core or 2.1 GHz quad-core processor. For substation automation projects, it includes an integrated video port and a human-machine interface (HMI) for localized viewing and control. All products in the RTAC line include a real-time operating system and provide 1 ms deterministic automation processing cycle times using an IEC 61131-3 logic engine. For time-critical automation and control projects, the SEL 3555 is up to 55 times faster for large projects that incorporate fast logic and HMI visualization.

Additional features include modular port expansion that offers up to 10 independent Ethernet ports or up to 26 EIA-232/485 serial ports; redundant power supplies that improve availability when connected to two power sources; HTML5 technology that supports enhanced graphics for the Web-based HMI; configuration monitoring functionality that detects and alerts when changes are made to the connected intelligent electronic devices; and a generic flex parser that allows the SEL-3555 to communicate with most any device.

The SEL-3555 provides reliable operation in harsh environments and is designed and tested to withstand vibration, electrical surges, fast transients and extreme temperatures. It also meets or exceeds the requirements of IEEE 1613, Standard Environmental and Testing Requirements for Communications Networking Devices in Electric Power Substations. Configuring the SEL-3555 is intuitive using the included ACSELERATOR RTAC SEL-5033 software, and projects can be exported from one RTAC product to another, simplifying migration of projects to the SEL-3555.
