FUNCTIONAL DESCRIPTION:

DS2020FEBNRP075A is a Field Exciter Module manufactured and designed by General Electric as part of the Mark V Series used in GE Speedtronic Gas Turbine Control Systems. A Field Exciter Module, also known as a field excitation module or field exciter, is a component used in electrical power systems to control the excitation of synchronous generators. Synchronous generators are widely used to produce electricity in power plants, and they rely on a magnetic field to generate electrical power. The Field Exciter Module is responsible for providing the necessary direct current (DC) to the generator's field winding, which creates the magnetic field. By controlling the field current, the output voltage and reactive power of the generator can be adjusted. The module typically consists of electronic components, such as power converters, voltage regulators, and control circuits. It may also include sensors to monitor the generator's performance and feedback signals to ensure stable and reliable operation.

FUNCTIONS OF FIELD EXCITER MODULE:

Excitation Control: It regulates the field current to maintain the desired generator voltage and reactive power output. By adjusting the field current, the module can control the generator's output voltage and reactive power independently.

Voltage Regulation: It stabilizes the generator's output voltage by adjusting the field current based on the feedback signals from voltage sensors. This ensures that the generated voltage remains within acceptable limits, even under varying load conditions.

Reactive Power Control: It enables the generator to supply or absorb reactive power as required by the electrical grid. Reactive power control helps maintain grid stability and voltage levels.

Fault Protection: The module incorporates protective features to detect abnormal conditions, such as overvoltage or overcurrent, and initiates appropriate protective actions to safeguard the generator and the power system.

FREQUENTLY ASKED QUESTIONS:

What is a Field Exciter Module?

A Field Exciter Module is a device used in electrical systems, particularly in generators and motors, to control and regulate the magnetic field. It is responsible for exciting or energizing the field winding, which in turn generates the magnetic field required for the operation of the device.

What is the function of a Field Exciter Module?

The main function of a Field Exciter Module is to control the strength and stability of the magnetic field in a generator or motor. By regulating the excitation current flowing through the field winding, it ensures that the output voltage or speed of the device remains within the desired range.

Can a Field Exciter Module be replaced or repaired?

Depending on the extent of the damage or malfunction, a Field Exciter Module can sometimes be repaired by replacing faulty components or repairing the control circuitry. However, in some cases, it may be more cost-effective or practical to replace the entire module. The best course of action can be determined by an expert after assessing the specific situation.
