GE EX2100 modular

Description

The EX2100e Excitation system is GE Energy’s advanced
platform for generator excitation controls. The EX2100e
builds on the EX2100 experience of over 700 units in gas,
steam, and hydro applications (for new units and upgrades) in
addition to GE’s 50 years of experience with over 6,000
excitation systems in 70 countries.
The EX2100e has enhanced technology, including a new
controller from the Mark* VIe control line and the current
ControlST* software suite. In addition, the EX2100e offers a
35A brushless dual redundant regulator option for cost
effective reliability.
Controllers
Now, excitation shares the same controller with Mark VIe
application-based turbine and plant controls. These singleboard controllers offer flexible, compact packaging and more
computing power for advanced control features to enhance
grid dynamics and generator performance. In addition, the
stand-alone controllers can be easily upgraded for better lifecycle support of the equipment.
I/O Interface
The controllers communicate to the I/O interface through a
100 MB Ethernet I/O network that can be extended for
remote I/O modules. The large, inflexible I/O cables of the
EX2100 are eliminated. Since there are less electronics in an
EX2100e, a smaller spare parts inventory is needed. Similarly,
less active electronics increases the mean-time-betweenfailure (MTBF) and improves system reliability.
Controllers, I/O interface, and the bridge(s) are mounted
inside the EX2100e cabinet. Only an optional touchscreen
panel remains on the door for local control and display of
generator parameters along with alarm history and alarm/
fault help.
