UAD149A0001-3BHE014135R0001 is an excitation system, refers to the supply of synchronous generator excitation current of the power supply and its ancillary equipment. It is mainly composed of two main parts: excitation power unit and excitation regulator. The excitation power unit is responsible for providing the excitation current to the rotor of the synchronous generator, while the excitation regulator controls the output of the excitation power unit according to the input signal and the given regulation criteria. In addition, the excitation system also includes a magnetic disconnection device, which can quickly weaken the rotor magnetic field and reduce the fault loss when there is a failure inside the generator.

The main functions of the UAD149A0001-3BHE014135R0001 include:

According to the change of the generator load, the excitation current is adjusted to maintain the machine terminal voltage at a given value.

Control reactive power distribution among generators running in parallel.

Improve the static and transient stability of generators running in parallel.

When there is a fault inside the generator, the magnetic field is removed to reduce the fault loss.

In addition, according to the operation requirements, the excitation system can also implement the maximum excitation limit and the minimum excitation limit of the generator.

Excitation system has great influence in power system and plays an important role in the safe and stable operation of power system and generator itself. With the development of technology, the modern excitation system is developing in the direction of digital and adaptive regulation to better meet the needs of the power system.
