Description

3BHE046836R0101 is a product from ABB, with the model number GFD563, which is an excitation controller. Here are its detailed specifications:

Features
Precise Control: Capable of receiving voltage and reactive power signals from the generator, and calculating the target value of the excitation current according to the set excitation control strategy. By controlling the output current of the thyristor rectifier, the excitation current is adjusted to achieve precise control of the generator’s output voltage and reactive power.
Voltage Stabilization: When the generator load changes, the generator terminal voltage can be stabilized by adjusting the magnetic field strength, keeping the output voltage and current of the generator set at the given values.
Reactive Power Distribution: Reasonably distribute reactive power among parallel-running units to improve power system stability, including static stability, transient stability, and dynamic stability.

Fault Protection: When the generator experiences faults such as overvoltage or overcurrent, the excitation controller will immediately send corresponding signals to notify the monitoring system for handling, in order to reduce the extent of fault damage. Signal Acquisition and Processing: Capable of acquiring analog signals from the power system into the control chip, analyzing and calculating based on the current operating conditions, and inputting the calculated excitation control signals into the excitation power module, among other functions.

Application field: This excitation controller is one of the core control devices of hydroelectric generator units, widely used in generator excitation control within power systems, providing important technical support for the stable operation and optimization of power systems.
