FUNCTIONAL DESCRIPTION:

DS200FECBG1A is a Field Exciter Control Board manufactured and designed by General Electric and is part of the EX200 Series used in GE Excitation Turbine Control systems. A Field Exciter Control Board is a critical component in the control and regulation of the excitation system for generators, particularly in turbine-driven power generation systems. Its primary function is to manage the generator's field excitation, which directly influences the voltage output and stability of the generator during various operational states. This control is essential for maintaining the generator’s performance and ensuring the stability of the electrical power it produces.

FEATURES:

• Voltage Regulation: The board controls the field voltage of the generator's excitation system, adjusting the generator’s output voltage to maintain consistent power levels. This ensures that the generator's voltage is stable, even under varying load conditions.

• Microprocessor-Based Control: The Board utilizes advanced microprocessor technology to manage control algorithms, enabling precise and real-time adjustments to the excitation system. This contributes to faster dynamic response and higher efficiency in voltage regulation.

• Fault Detection and Protection: The board is equipped with fault detection capabilities, and monitoring parameters such as over-voltage, over-current, and over-excitation. In case of abnormal conditions, it triggers protective actions, such as reducing the excitation or shutting down the generator, to prevent equipment damage.

• Integrated Diagnostics: Self-diagnostic routines continuously monitor the board’s performance, ensuring early detection of potential issues. This feature helps reduce downtime and facilitates preventive maintenance.

• Communication Interface: The Board communicates with the turbine control system (Mark V or Mark VI systems) through a digital communication network. This ensures synchronization between generator excitation and the overall turbine operation.

• Analog and Digital I/O: The board has both analog and digital inputs and outputs to interface with various sensors, actuators, and other control modules in the system, ensuring comprehensive control over the excitation process.

FREQUENTLY ASKED QUESTIONS:

What is a Field Exciter Control Board?

The Field Exciter Control Board regulates the excitation system of a generator, controlling the flow of current to the rotor to maintain stable voltage output and enhance dynamic response to load changes.

What are the typical voltage and current ratings for the Field Exciter Control Board?

The Field Exciter Control Board typically operates within a voltage range of 24V to 48V DC for control power, while the excitation output can be in the range of 100V to 400V, depending on the generator’s specifications. The output current is generally rated between 5A to 20A, but this can vary by model.

How does the Field Exciter Control Board implement voltage regulation?

The board employs a closed-loop feedback control system, measuring the generator’s output voltage and adjusting the excitation current accordingly. This allows it to compensate for load changes in real-time, ensuring that the output voltage remains within specified limits.
