description The invention provides an intelligent monitoring method and system for a generator de-excitation system, and the method comprises the steps: collecting the de-excitation current of each branch through a Hall sensor, obtaining the energy consumption of a de-excitation resistor of each branch through the integral operation, and carrying out the transverse comparison of the current and the energy consumption of each branch, if the deviation between a certain branch and other branches exceeds a set value, an alarm is given; and longitudinally comparing the historical data of each branch, and giving an alarm if the deviation between a certain branch and the historical data exceeds a set value. Through transverse comparison of each branch and longitudinal comparison of current and energy consumption of the same branch at different time, intelligent monitoring of the de-excitation resistor and the de-excitation system is realized, and current-sharing and energy-sharing coefficients of each branch are maintained, the
