GE’s Multilin™ D400 is a secure, substation-hardened gateway that collects metering, status, event, and fault report data from serial or LAN based Intelligent substation devices. The D400 summarizes data from the substation devices and makes it available locally/remotely through a standard secure web browser (HTTPS).
It supports serial and/or LAN connections to SCADA masters. TCP/IP network connections are supported over the built-in Ethernet and the modem interface.
The D400 collects data from substation protection, control, monitoring, RTU, and intelligent devices, pre-processes the data and moves it up to EMS and DMS SCADA systems providing centralized substation management.
The D400 provides the computing platform necessary to automate substation procedures, such that intricate processes are carried out safely and efficiently by creating custom automation programs using IEC 61131 compliant tools and performs basic math functions on data points using the built-in Calculator tool.
Using pass-through connections, users can extract valuable non-operational data such as digital fault recording (DFR) records and event files. The user can also access the historical log files and upload the archived data for trending and analysis.
The D400 allows maintenance and relay engineers to securely access substation devices, locally or remotely, through advanced visualizations and communication tools, increasing productivity.
