The invention relates to the field of hydropower station operation control, and provides an improved global gradient method for constant flow simulation of a hydropower station complex pipe network in order to facilitate constant flow simulation of a series hydropower station pipe network system, which comprises the following steps: step 1, assigning initial values to parameters of the hydropower station pipe network system; 2, based on the flow characteristic curve, a water turbine interpolation strategy is adopted, water turbine unit parameters are solved, and water turbine dynamic iteration resistance parameters are formed; 3, calculating an iteration water head vector H (tau + 1), an iteration common pipeline flow vector Q (p tau + 1) and an iteration water turbine flow vector Qt (tau + 1); and 4, judging whether an iteration requirement is met or not according to the Qt (tau + 1), if the requirement is met, exiting iteration, and otherwise, returning to the step 2 for recalculation ...
