The invention provides a minor-cycle real-time generation schedule, which comprises the following steps of: S1, determining units participating in real-time generation schedule computing by two stages of dispatching centers; S2, judging whether the difference between a load predicted value Ps used by an intraday generation schedule in the next schedule time and an ultra-short-term load predicted value Ps' used by the intraday generation schedule in the next schedule time is equal to 0 or not, if the difference is equal to 0, executing the step S7, and if the difference is not equal to 0, executing the step S3; S3, respectively working out load deviation values deltaPs,A and deltaPs,B which need to be respectively borne by the units which respectively correspond to the two stages of dispatching centers in the next time; S4, performing statistics adjustable capacity sums deltaPC,A and deltaPC,B of the units which respectively correspond to the two stages of dispatching centers; S5, working out load deviation values deltaPLF,A and deltaPLF,B respectively and finally distributed by the two stages of dispatching centers; S6, working out the adjustment power of every unit of the two stages of dispatching centers; and S7, executing the step S1 after the real-time generation schedule of each unit is obtained. Only the predicted values in the next schedule time are used every time, so that the output of each unit more approaches to the requirement of an actual load.
