Generator excitation system tasks:
(1) Before the generator is connected to the grid, adjust the terminal voltage output by the generator;
(2) After the generator is connected to the grid, adjust the reactive power borne by the generator;
(3) Improve the static and dynamic stability of parallel operation of synchronous generators
Static stability: The use of a sensitive and fast excitation regulation system can improve the stability of the generator under small disturbances (static stability);
Dynamic stability: The excitation regulation system with fast response and high peak voltage can improve the stability of the generator under large disturbances (dynamic stability, transient stability);
(4) In the event of a generator accident, the rotor winding is demagnetized quickly to protect the safety of the generator
