Specifications

Description

IS200EDCFG1ADC is an Exciter DC Feedback Board developed by GE. It is a part of EX2100e excitation system. The board plays a critical role in the EX2100e control system by measuring field current and field voltage at the SCR (Silicon-Controlled Rectifier) bridge.It establishes a vital link with the EISB in the control panel, facilitating communication over a high-speed fiber-optic link.This advanced communication method offers key advantages, including voltage isolation and high noise immunity ensuring reliable and accurate data transfer between the boards.

Applications

Power Industry: GE EX2100 excitation cabinets for thermal power plants (coal-fired/gas turbines) and hydroelectric power plants.

Heavy Industrial Power Plants: Excitation control for large synchronous motor drive systems in steel mills, aluminum plants, etc.

Marine Propulsion: Power system monitoring for chemical-engineered ships or large cruise ships using all-electric propulsion systems.

Key Features

1 Measurement of Field Current and Voltage: The board is equipped with the capability to precisely measure both field current and field voltage at the SCR bridge. This information is crucial for monitoring and controlling the excitation process in power generation systems.

2 Communication via Fiber-Optic Link: The board establishes communication with the EISB board through a high-speed fiber-optic link. This communication method provides several advantages, including high data transfer rates, electrical isolation, and immunity to electromagnetic interference (EMI).

3 Voltage Isolation: The fiber-optic link ensures voltage isolation between EDCF and the EISB board. This is essential for maintaining electrical safety and preventing potential issues related to voltage differences.

4 High Noise Immunity: The utilization of fiber optics enhances the system's noise immunity. It minimizes the impact of electrical noise and interference, contributing to the overall reliability of the communication link.

5 Two-Fiber Configuration: The communication link utilizes two fibers—one for field current and one for field voltage. This dual-fiber configuration allows for independent transmission of each signal, ensuring accurate and uncompromised data transfer.

6 Fiber Types for Different Distances: It supports two types of fibers, each suitable for different distances: Plastic Type Fiber designed for distances up to 10 meters, and Hard Clad Silica Type suitable for longer distances, reaching up to 90 meters.

7 Minimum Bending Radius: The minimum bending radius for these fiber-optic cables is specified at 1.5 inches. Adhering to this requirement ensures optimal performance and longevity of the cables.

8 Fiber Types and Distances: Plastic Type Fiber is ideal for shorter distances, providing reliable communication up to 10 meters, while Hard Clad Silica Type is suited for longer distances, extending the communication range to up to 90 meters.

Benefits of the Field Voltage Feedback Circuit

Scalability: The selector settings enable scalability, accommodating diverse bridge applications.

Precision: The differential amplifier enhances precision by amplifying voltage differentials.

Dynamic Response: The VcO ensures a dynamic response to changes in field voltage, offering real-time monitoring capabilities.
