The invention discloses a coal-fired power plant ash conveying system dynamic energy-saving control method based on actual coal quality parameters. The method comprises the steps: 1) establishing a unit fire coal real-time coal quality parameter model for an ash conveying system; 2) carrying out an optimal ash falling time control test on the ash conveying system by using the real-time coal quality parameter model of the unit fire coal in the step 1) to obtain an ash falling time control curve of the ash conveying system, which adapts to the dynamic ash flow, of each ash conveying unit; 3) automatically setting the ash falling time of each ash conveying unit according to the ash falling time control curve of the ash conveying system in the step 2), the coal quality parameters of each raw coal bunker and the coal quantity of each coal feeder in combination with the ash falling time control curve of the ash conveying system adapting to the dynamic ash flow; 4) if all the ash conveying units operate normally in the ash conveying process, performing the step 3) circularly; and if an abnormal phenomenon occurs in a certain ash conveying unit, stopping ash falling immediately, and directly performing a fly ash conveying program, meanwhile, automatically settting a safety margin coefficient to give an alarm prompt on a monitoring picture.
