Excitation control system is a feedback control system formed by generator end parameters, excitation regulation unit and rectifier unit. The system not only regulates the output voltage of the generator, but also regulates the reactive power, power factor and excitation current of the generator and other important parameters to ensure that the power system under normal operation, the high voltage side voltage of the generator and the voltage of the entire grid are maintained at the same level, and the reactive load between the generators is rationally allocated to improve the stability of the power system.

The hardware components of excitation control system mainly include excitation regulator, power rectifier and degaussing system. Among them, the IS200ESYSH3A excitation regulator is responsible for controlling the size of the excitation current, the power rectifier converts alternating current to direct current to supply the excitation windings, and the deexcitation system is used to quickly cut off the excitation current when the generator is shut down.

In addition, the excitation control system has a variety of functions, such as automatic voltage regulation mode, excitation current regulation mode, constant power factor or constant reactive power operation mode, to meet different operating requirements. At the same time, in order to ensure the safe and stable operation of the power grid and the unit, the excitation system should also attach the necessary restrictions and protection functions, such as overexcitation limit, underexcitation limit, V/Hz limit.

In short, the IS200ESYSH3A excitation control system is an important part of the power system, which plays an important role in improving the stability of the power system and the operation efficiency of the generator. With the development of power electronic technology, the performance and reliability of excitation control system have been continuously improved, which provides a strong guarantee for the safe and stable operation of power system.
