D200 Substation Automation Platform - GE D20 Technical Overview

GE Grid Solutions

1.5 D200 Substation Automation Platform

The D200 has the computing power and expandability needed to provide substation automation
in larger substations. This is achieved through an innovative design that employs multiple D20
processors, communicating over a VME bus.
The D200 has the processing power to monitor and control thousands of I/O points. It can run
sophisticated automation applications, such as our LogicLinx* programmable logic control,
without compromising performance.
GE Grid Solutions has installed D200 systems with point counts exceeding 80,000. Contact GE
Grid Solutions for further information on engineering large systems.
1.5.1 D200 Features
• RS-232/RS-485 ports support large numbers of host systems and IEDs
• VME bus architecture provides high scalability and performance for adding serial ports,
LAN options, and memory
• Data is integrated and coordinated, so different applications access a single, real-time
database
• Optional redundant configuration for high reliability at critical sites (see section 2.9,
Redundancy)
• Hardened to perform critical control functions in the substation environment, in accordance
with applicable IEEE
