The invention discloses a method for controlling the active power of a hydroelectric unit in a single recommended operation area, and belongs to the technical field of hydroelectric power generation control. Divide the automatic power generation control function into the power station-level AGC module, the unit-level PLC module and the unit-level governor module and then assign tasks, determine the parameters, assignment relationships and dependencies; establish all possible distribution modes and corresponding combinations that include AGC control units The intermediate table of the operation interval determines the optimal unit distribution mode of the units put into AGC control, and calculates the single-unit AGC active power distribution value, and performs the active power control of the hydroelectric unit in the single-recommended operation area. It is suitable for hydropower stations where the intervals are divided into vibration zone 1→restricted operation zone→vibration zone 2→recommended operation zone from low to high. It can quickly calculate the single-unit AGC active power of each unit according to the total active power setting value of the hydropower station. The distribution value and the active power setting value of a single unit can meet the operation requirements of the unit avoiding the vibration area and the restricted operation area at the same time.
