The LS2100e is available for both new unit GE heavy-duty gas
turbines and retrofit applications. It can be installed to replace
GE’s aging Direct-o-Matic Plus static starter, or as an LS2100e
Digital Front End (DFE) for modernization of GE’s Innovation Series
Control starters.

Member of the Mark* VIe Family
The LS2100e uses the same controller,
communication architecture, operator interfaces
and ControlST* software suite as the as Mark VIe
family of turbine, generator and plant controls—
simplifying plant operations and maintenance.

Reliability
The LS2100e hardware is designed for high reliability. Reduced
card counts, the ability to quickly remove individual cells, and
other design features help to minimize mean-time-to-repair. The
powerful UCSB controller allows integration of system cooling
control, eliminating the supplemental cooling control PLCs from
prior designs. Improved hardware diagnostics and maintenance
management features help improve staff productivity and insure
starting reliability.

The overall starting reliability of a critical turbine-generator may
be enhanced with the installation of redundant static starters. The
LS2100e is designed to be applied in a one-on-one configuration
or can be configured to support a multiple starter configuration
where redundant starters can be used to start one or more
turbines, allowing improved system flexibility and reliability.

Performance
The LS2100e provides high acceleration torque from turning
gear speed, reducing unit starting times and improving starting
reliability. Since static starters control the generator as a
synchronous motor, there is no need for auxiliaries—saving
space around the turbine base. The turbine start sequencing is
coordinated between the turbine controls, exciter, and the static
starter controls via a reliable high speed unit data highway.
System functions are monitored via the Mark controls Human
Machine Interface (HMI).

Protection
The LS2100e provides a comprehensive set of drive protective
functions:
• Instantaneous overcurrent
• Bridge differential current
• Generator overvoltage
• Source bridge undervoltage and overvoltage
• Ground fault
• Bridge coolant over temperature, low resistivity, low pressure,
functions:
• Instantaneous overcurrent

• Generator overvoltage
• Source bridge undervoltage and overvoltage
• Ground fault
• Bridge coolant over temperature, low resistivity, low pressure,
high or low level
• Shorted thyristor
• No generator field at start
• No generator field at start
Operability
The LS2100e platform features a simplified hardware design and
leverages the power of GE’s ToolBoxST to create a system that
has more capability, but is also easily maintained and operated.
The system is operated and managed through the existing HMIs;
alarms and events are time-stamped at their source by the
LS2100e, then integrated with the rest of the alarm management
system (along with control parameters) in a common time-
coherent database. This enhances alarm resolution and analysis
of the turbine-generator set as a single system. System and
alarm management includes a full set of system and starting
sequence summaries, thermal performance and extensive card
and power converter diagnostics that include cell monitoring.
