In order to reduce the water consumption and improve the power station efficiency on the basis of meeting the power demand,a multi-objective fuzzy programming based load distribution method is studied.In order to minimize the total water consumption under the constraint conditions,a mathematical model for the economic operation of hydropower units is established.The combined dynamic vibration zone of the unit is established by using the mathematical combination theory.The multi-objective fuzzy programming algorithm is used to calculate the water consumption of the unit.I determines the level according to the unit weight and complete the distribution of the operating load of the hydropower unit.Through experimental demonstration and analysis,the proposed method can effectively avoid the vibration area of the unit and the frequent switching of the unit,and has good load distribution effect.The water consumption of the hydro motor unit for load distribution by the proposed method is significantly reduced,and the economic benefits are improved.It proves that the proposed method is more reliable.
