The invention discloses a traction station load prediction method based on a subway operation timetable, and the method comprises the steps: obtaining and building a single-vehicle traction load change curve library of a train based on the speed, braking force and traction force data of a train starting and braking stage, and obtaining and building a single-vehicle auxiliary energy consumption library of the train based on the temperature, passenger flow volume and power consumption data of the train; calculating and superposing a single-train traction load change curve library and a single-train auxiliary energy consumption library of a train in a subway station interval on the basis of station spacing and time table data in train running to form a total traction load power change curve, and distributing the total traction load power change curve among stations to a power supply interval among traction stations; and carrying out superposition calculation and obtaining a total traction load power change curve on each power supply interval, and changing the power change curve on each power supply interval into a power change curve on each traction station by adopting a power average distribution mode on the total traction load power change curve on each power supply interval.
