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.
Figure 6 D200 Substation Automation Platform
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.
