Running dispatching diagram drawing method capable of enabling comprehensive benefits of reservoir to be optimal

The invention discloses a running dispatching diagram drawing method capable of enabling comprehensive benefits of a reservoir to be optimal. The method comprises the following steps that 1, all-period breakage-proof water level or water quantity, water supply limiting water level or water quantity and water abandoning prevention water level or water quantity combinations meeting the annual design water supply guarantee ratio are calculated; 2, water supply quantity value indexes of all periods are set; 3, the water supply quantities of all periods within the year of the water supply quantity combinations meeting the annual design water supply guarantee ratio are multiplied by the value indexes of the corresponding periods; 4, the combination with the maximum whole-year water supply quantity value is extracted from all the combinations in the step 3. The problem that in tradition typical year method calculation, due to the fact that typical years and year number selection vary with each individual, different design persons draw different dispatching diagrams is solved, and the problem that the whole breakage year is removed through a breakage year removal method, and the water supply guarantee ratio samples of all periods within the year are reduced is solved. Water resources can be fully utilized, the running safety and reliability of the reservoir are improved, and the difference of the water supply quantities within different periods can be reflected.
