Excitation control unit system 151X1235DB15SA03

151X1235DB15SA03 EX2100e excitation control regulator system is GE’s latest advanced control system

for steam, gas or hydroelectric generators, suitable for new units and modified units.

Control hardware and software design are closely coordinated with

GE’s system and control engineering to ensure a true system solution.

Integration between the excitation control system, turbine control system,

static start control system, integrated control system (ICS) and human machine interface (HMI) is

seamless.

For stand-alone retrofit applications, integration with the customer’s distributed control system (DCS) is

supported via serial or Modbus® Ethernet.

This document is specifically for the application of the 35 A and 120 A (nominal) series EX2100e control

regulator systems.

Control Hardware

The 151X1235DB15SA03 EX2100e regulator system is available in multiple configurations to

provide control flexibility for thyristor and regulator systems.

For small regulator systems, two pulse width modulation (PWM) power converter modules

use insulated gate bipolar transistors (IGBTs) to provide up to 35 A or 120 A nominal output.

These systems can support the following applications:

• Saturated current transformer/power voltage transformer (SCT/PPT) regulators

• Brushless exciter regulators

• Direct current (dc) rotary exciter regulators

Features:

. Direction of each 8-bit port is individually programmable

.64 mA sink current capability (15 mA source) .

. Separate board address decoding for control and data registers .

. Built-in test logic for fault detection and isolation .

. Highly reliable DIN-type I/O connectors .

. 8-bit, 16-bit, 32-bit transfers

The VMIVME-2510B is a member of the VMIC Megamodule family, which is designed for universal

programming.

The subsystem can be configured with consecutive I/O addresses to conserve memory.

These products (VMIVME-1110. VMIVME-2120. VMIVME-2130. and VMIVME-2510B) are designed with

two sets of board address switches to provide efficient memory address mapping for CSR and I/O addresses.

The CSR address switches can be configured so that all CSRs on the various boards in the system can be mapped to contiguous memory locations.

Megamodule products are also designed to support 8-bit, 16-bit and 32-bit data transfers.

Specific hardware has been designed into the VMIVME-2510B to support the built-in test functions.

The VMIVME-2510B supports off-line and on-line fault detection and isolation. The front panel Fail LED is used to indicate when a fault exists on this board.

The LED is illuminated at power-up or reset. The LED can be turned off after successfully completing board level diagnostics.

The IC693CPU363 is manufactured by GE Fanuc. This module is a controller

from the Series 90-30 of Programmable Logic Controllers (PLC). 

This controller is responsible for executing the user program stored within its user memory

as well as managed communication exchanges between compatible devices such as programming workstations,

Human Machine Interface (HMI), Supervisory Control and Data Acquisition (SCADA), Databases and other 3rd party hardware and devices.

The IC693CPU363 features a 80386EX processor with clock speed of 25 MHz and typical scan rate of 0.22 ms per 1K of logic for Boolean contacts.

The embedded memory of this controller amounts to 240KB which is internally partitioned

to accommodate different registers and internal functions.

It has Two (2) serial ports, One (1) port having a physical interface of RJ45 while the other port having a 15-pin sub-D connector,

both supporting RS232 and RS485 communication standards.

It also has a tertiary RS485 port which is situated on the power supply.

All these ports allow download, upload of user program, perform commissioning tasks and fine tuning of the program.

These ports operate independently and may be configured for simultaneous operation to accommodate

other data exchange functions such as communication with visualization components.

Other communication protocols supported by the IC693CPU363 are Ethernet, FIP, Profibus, GBC, GCM, GCM+ option modules.

Once programmed by the VMEbus host, the

VMIVME-2540 ICC performs these functions

automatically. The on-board CPU maintains data structures

in shared local memory for buffering measurements and

queueing control commands. Measurement functions are

also supported by a Continuous Measurement Mode in

which measurements are made repeatedly without host CPU

involvement. I/O connections are routed through

high-density connectors located on the front panel with

support for differential and single-ended signal levels. The

user data exchange interface for measurement and

generation modes complies with ANSI/IEEE Standard

754-1985 for 32-bit floating-point arithmetic. Integer modes

operate with two’s complement signed arithmetic and with unsigned arithmetic.

TECHNICAL DESCRIPTION— The VMIVME-2540 ICC is comprised of three sections: the

VMEbus slave DTB interface which arbitrates for the local

CPU resources, the CPU with firmware and support logic,

and the circuitry which implements the measurement and control functions.

PRODUCT OVERVIEW — The VMIVME-2540

Intelligent Counter/Controller (ICC) is a VMEbus slave I/O

module designed to provide high-precision digital

AC Power Source Connections

The Hot, Neutral, and Ground wires from the

20 VAC power source or L1, L2. and

Ground wires from the 240 VAC power source connect to the system through the top three

terminals of the terminal strip on the front of the power supply.

DC Power Source Connections

Connect the + and – wires from the

25 VDC (nominal) power source to the top two

terminals on the terminal connector.  These connections are not polarity-sensitive on an

AC/DC input power supply.  (However, the DC Input-only type supplies, which are

discussed later in this chapter, are polarity sensitive.)

Input Overvoltage Protection Devices

This information applies to all Series 90-30 power supplies except IC693PWR322

and IC693PWR328.  The overvoltage protection devices for this power supply are

connected internally to pin 4 on the user terminal strip.  This pin is normally connected to

frame ground (pin 3) with the supplied jumper strap which is installed at the factory.  If

overvoltage protection is not required or is supplied upstream, this feature can be disabled

by  removing the jumper strap from pins 3 and 4.

Field Wiring Connections for the AC/DC Input Power Supplies

The two AC/DC input power supplies have six terminals for user connections.  These connections

are described below.

AC Power Source Connections

The Hot, Neutral, and Ground wires from the

20 VAC power source or L1, L2. and

Ground wires from the 240 VAC power source connect to the system through the top three

terminals of the terminal strip on the front of the power supply.

The IC693PWR330 High Capacity Power Supply is rated for 30 watts output.  For applications

requiring greater +5V current capacity than is available with the standard supply

(IC693PWR321), this supply allows all 30 watts to be consumed from the +5V supply.  It can

operate from an input voltage source in the range of 85 to 264 VAC or

100 to 300 VDC. This power  supply provides the following outputs:

• +5 VDC output.

• +24 VDC Relay power output which provides power to circuits on Series 90-30  Output Relay

modules.

• Isolated +24 VDC, which is used internally by some modules, can also be used to provide

external power for 24 VDC Input modules.
