Abstract

The invention discloses a pulverizing system optimal distribution method based on a self-adaptive chaos particle swarm. The pulverizing system optimal distribution method belongs to the field of power system optimal distribution, calculates to obtain a total coal feed quantity of coal pulverizers according to given load of a unit, and distributes the total coal feed quantity to the N coal pulverizers of the unit reasonably so that the total unit consumption of pulverizing is minimal. The pulverizing system optimal distribution method is characterized by comprising the steps of: calculating a coal feed quantity of the unit according to unit load, and then determining different operation modes of the N coal pulverizers according to an output range of each coal pulverizer; and adopting a self-adaptive chaos particle swarm algorithm to calculate unit consumption of pulverizing of each operation mode, and determining the operation mode for the coal pulverizers according to the minimal unit consumption of pulverizing. The pulverizing system optimal distribution method can solve the unit start-up and shut-down problem of an intelligent optimization algorithm and the equality constraint problem of the particle swarm algorithm.
