Hydropower Station Equipment Solution

Excitation System：The main function of the excitation system is to supply current to the rotor windings of the hydrogenerator to establish a magnetic field. Direct current (DC) is typically used to create this magnetic field.

Main Functions of the Excitation System：

(1) To supply excitation current to the synchronous generator and adjust the excitation current.

(2) To provide forced excitation, enhancing the stability of the power system.

(3) To perform forced de-excitation of the generator, limiting overvoltage.

(4) To carry out de-excitation in the event of a short circuit.

(5) To distribute the reactive power of generators when multiple units are operating.
