ABB has introduced a new excitation control module, the PCD231B101 3BHE025541R0101, designed for generator excitation systems to ensure that the excitation current and voltage of the generator are maintained at the right level. This module uses a three-phase fully controlled bridge thyristor rectifier circuit to provide DC excitation current to the rotor windings of synchronous motors. It also has a magnetic circuit, which is composed of thyristor and diode in inverse parallel to form a high-power electronic switch to ensure that the rotor excitation winding is neither open nor short circuit during the asynchronous start of the synchronous motor, so as to avoid overvoltage and overcurrent under the excitation winding.

The PCD231B101 3BHE025541R0101 module supports communication interfaces and can exchange data and communicate with other devices, control systems or monitoring systems. It also has current and voltage monitoring functions, and can adjust the excitation current and voltage of the generator to meet the needs of the power system. In addition, the module has protection and security functions, as well as alarm and diagnostic functions.

The introduction of this excitation control module further enriches ABB’s product line in the field of power system automation and provides customers with more choices. Its efficient processing power, modular design, powerful communication functions and high reliability make it an ideal choice for industrial automation. With the continuous progress of industrial automation technology, PCD231B101 3BHE025541R0101 module is expected to play a more important role in the future industrial production.
