Abstract: The excitation control module of synchronous generator is the key equipment for power production

and safe operation，and the localization rate of its key materials is low. Based on the control performance of the

synchronous generator excitation control module，starting from the research of chip independent controllability，

following the basic requirements of reliability，flexibility，and fast response of the generator excitation control

module，a design principle and implementation method of the independent controllable excitation control module

from a hardware perspective was introduced. The autonomous controllable excitation control module has been put

into commercial operation in hydroelectric power plants，and the operation effect is good.

Key words: autonomous control；synchronous generator；excitation；control module
