Description
technical field [0001] The invention relates to the field of excitation control of generator electrodes, in particular to an excitation control system. Background technique [0002] The existing generator excitation controller calculates the control voltage by comparing the generator voltage with the given voltage, and converts the calculated control voltage into the corresponding excitation output current, so as to achieve the purpose of controlling the generator voltage. [0003] The main control unit of the generator excitation controller collects the analog quantity of the working voltage in real time. When an emergency occurs and the generator excitation controller needs to be protected, the excitation controller is ordered to be shut down through the protection software programmed in the main control unit in advance. Power-off protection is performed on the excitation controller. [0004] The disadvantage of the existing generator excitation controller is that the sta...
