TECHNICAL SPECIFICATIONS FOR GE - DS3800NMFA

DS3800NMFA is a Motor Field Regulator Board manufactured and designed by General Electric as part of the Mark IV Series used in GE Speedtronic Gas Turbine Control Systems. The Motor Field Regulator (MFR) board is a critical component in the control system of gas turbines. Its main function is to regulate the excitation current of the generator's field winding. The MFR board monitors the output voltage of the generator and adjusts the excitation current to maintain a stable output voltage. The MFR board typically consists of a power amplifier, a feedback circuit, and a control circuit. The power amplifier provides the necessary current to the field winding, while the feedback circuit measures the output voltage and provides a signal to the control circuit. The control circuit then adjusts the power amplifier to maintain the desired output voltage.

FEATURES:

The Motor Field Regulator Board (MFRB) in turbine control systems typically features the following components and functions:

Control Circuitry: The MFRB contains a control circuit that regulates the current and voltage of the turbine's field winding. This circuitry is responsible for monitoring the generator output and adjusting the field current and voltage as necessary to maintain a stable output.

Voltage Regulator: The MFRB contains a voltage regulator that ensures that the voltage supplied to the turbine's field winding remains constant, even as the generator load varies.

Current Regulator: The MFRB contains a current regulator that ensures that the current supplied to the turbine's field winding remains constant, even as the generator load varies.

Protection Features: The MFRB may also include various protection features, such as overvoltage and overcurrent protection, to prevent damage to the turbine and other components in the system.

Communication Interface: In some cases, the MFRB may include a communication interface that allows it to communicate with other components in the turbine control system, such as a supervisory control and data acquisition (SCADA) system.
