There are over 4,000 first andsecond generation GE digitalexcitation controls operating in60 countries.

The EX2100e Excitation Control Regulator system is GE's most recent state-of-the-artcontrol system for steam, gas, or hydro generators for both new and retrofit units. Controlhardware and software design is closely coordinated between GE's system and controlsengineering to ensure delivery of a true system solution. Integration is seamless betweenExcitation Control systems, Turbine Control systems, Static Starter Control systems,Integrated Control Systems (ICS), and the Human-machine Interface (HMI). Forstand-alone retrofit applications, integration with customer distributed control systems(DCS) through serial or ModbuseEthernet is supported. This document specificallyaddresses applications for the 35 A and 120 A (nominal) series of EX2100e Control

Regulator systems.

2 Control Hardware

The EX2100e Regulator system is available in several configurations to provide controlflexibility for Thyristor and Regulator systems. For small Regulator systems, twopulse-width modulated (PWM) power converter modules use Insulated Gate BipolarTransistors (IGBT) to provide up to 35 A or 120 A nominal output. These systems cansupport the following applications:

Saturable Current Transformers / Power Potential Transformers (SCT/PPT) regulator

Brushless exciter regulator

Direct current (dc) rotating exciter regulator

In the SCT/PPT regulator and de rotating exciter regulator applications, the EX2100eRegulator system can de-sensitize the effect of the exciter time constant. It incorporatesdirect measurement of the generator field voltage and field current to enhance speed ofresponse to system transients.

The architecture is a single control with a single Power Control Module (PCM) or dualcontrol with dual PCM, including a customer interface sub-system, optional diagnosticlocal operator interface (touchscreen), optional control operator interface (COI) remotetouchscreen interface, control power input module, and PCM. The PCM consists of abridge interface sub-system, power bridge, optional ac and dc filter networks, andalternating current (ac) and/or de isolation devices. For expanded input and output (I/O)capability, either VersaMaxe or Mark* VIe control IONet I/O modules may be added.

The EX2100e Regulator system supports Ethernet local area network (LAN)communication to the following:

Turbine controls and ICS, HMI, Proficy-based Historian, Programming Interface(PI-based) Historian, Onsite Monitoring System (OSM), and COI

Extended I/O modules using the Ethernet Global Data (EGD) protocol

Customer DCS through Ethernet or Modbus Ethernet remote terminal unit (RTU)

ToolboxST application

GE Onsite Support* for monitoring and diagnostics
